Deprecation of file_client_args in favor of backend_args +4. Added a new MMOCR tutorial notebook + +To know more about the updates in MMOCR 1.0, please refer to [What's New in MMOCR 1.x](https://mmocr.readthedocs.io/en/dev-1.x/migration/news.html), or +Read [Changelog](https://mmocr.readthedocs.io/en/dev-1.x/notes/changelog.html) for more details! + +## Introduction + +MMOCR is an open-source toolbox based on PyTorch and mmdetection for text detection, text recognition, and the corresponding downstream tasks including key information extraction. It is part of the [OpenMMLab](https://openmmlab.com/) project. + +The main branch works with **PyTorch 1.6+**. + +
+ +
+ +### Major Features + +- **Comprehensive Pipeline** + + The toolbox supports not only text detection and text recognition, but also their downstream tasks such as key information extraction. + +- **Multiple Models** + + The toolbox supports a wide variety of state-of-the-art models for text detection, text recognition and key information extraction. + +- **Modular Design** + + The modular design of MMOCR enables users to define their own optimizers, data preprocessors, and model components such as backbones, necks and heads as well as losses. Please refer to [Overview](https://mmocr.readthedocs.io/en/dev-1.x/get_started/overview.html) for how to construct a customized model. + +- **Numerous Utilities** + + The toolbox provides a comprehensive set of utilities which can help users assess the performance of models. It includes visualizers which allow visualization of images, ground truths as well as predicted bounding boxes, and a validation tool for evaluating checkpoints during training. It also includes data converters to demonstrate how to convert your own data to the annotation files which the toolbox supports. + +## Installation + +MMOCR depends on [PyTorch](https://pytorch.org/), [MMEngine](https://github.com/open-mmlab/mmengine), [MMCV](https://github.com/open-mmlab/mmcv) and [MMDetection](https://github.com/open-mmlab/mmdetection). +Below are quick steps for installation. +Please refer to [Install Guide](https://mmocr.readthedocs.io/en/dev-1.x/get_started/install.html) for more detailed instruction. + +```shell +conda create -n open-mmlab python=3.8 pytorch=1.10 cudatoolkit=11.3 torchvision -c pytorch -y +conda activate open-mmlab +pip3 install openmim +git clone https://github.com/open-mmlab/mmocr.git +cd mmocr +mim install -e . +``` + +## Get Started + +Please see [Quick Run](https://mmocr.readthedocs.io/en/dev-1.x/get_started/quick_run.html) for the basic usage of MMOCR. + +## [Model Zoo](https://mmocr.readthedocs.io/en/dev-1.x/modelzoo.html) + +Supported algorithms: + +

However, these methods cannot well cope with OCR tasks because of the difficulty in both instance-level text encoding and image-text pair acquisition (i.e. images and captured texts in them). This paper presents a weakly supervised pre-training method, oCLIP, which can acquire effective scene text representations by jointly learning and aligning visual and textual information. Our network consists of an image encoder and a character-aware text encoder that extract visual and textual features, respectively, as well as a visual-textual decoder that models the interaction among textual and visual features for learning effective scene text representations. With the learning of textual features, the pre-trained model can attend texts in images well with character awareness. Besides, these designs enable the learning from weakly annotated texts (i.e. partial texts in images without text bounding boxes) which mitigates the data annotation constraint greatly. Experiments over the weakly annotated images in ICDAR2019-LSVT show that our pre-trained model improves F-score by +2.5% and +4.8% while transferring its weights to other text detection and spotting networks, respectively. In addition, the proposed method outperforms existing pre-training techniques consistently across multiple public datasets (e.g., +3.2% and +1.3% for Total-Text and CTW1500). + +

Conventional template matching based approaches fail to generalize well to document images of unseen templates, and are not robust against text recognition errors. In this paper, we propose an end-to-end Spatial Dual-Modality Graph Reasoning method (SDMG-R) to extract key information from unstructured document images. We model document images as dual-modality graphs, nodes of which encode both the visual and textual features of detected text regions, and edges of which represent the spatial relations between neighboring text regions. The key information extraction is solved by iteratively propagating messages along graph edges and reasoning the categories of graph nodes. In order to roundly evaluate our proposed method as well as boost the future research, we release a new dataset named WildReceipt, which is collected and annotated tailored for the evaluation of key information extraction from document images of unseen templates in the wild. It contains 25 key information categories, a total of about 69000 text boxes, and is about 2 times larger than the existing public datasets. Extensive experiments validate that all information including visual features, textual features and spatial relations can benefit key information extraction. It has been shown that SDMG-R can effectively extract key information from document images of unseen templates, and obtain new state-of-the-art results on the recent popular benchmark SROIE and our WildReceipt. Our code and dataset will be publicly released. + +

Text Detection with Differentiable Binarization](https://arxiv.org/abs/1911.08947) + + + +## Abstract + +Recently, segmentation-based methods are quite popular in scene text detection, as the segmentation results can more accurately describe scene text of various shapes such as curve text. However, the post-processing of binarization is essential for segmentation-based detection, which converts probability maps produced by a segmentation method into bounding boxes/regions of text. In this paper, we propose a module named Differentiable Binarization (DB), which can perform the binarization process in a segmentation network. Optimized along with a DB module, a segmentation network can adaptively set the thresholds for binarization, which not only simplifies the post-processing but also enhances the performance of text detection. Based on a simple segmentation network, we validate the performance improvements of DB on five benchmark datasets, which consistently achieves state-of-the-art results, in terms of both detection accuracy and speed. In particular, with a light-weight backbone, the performance improvements by DB are significant so that we can look for an ideal tradeoff between detection accuracy and efficiency. Specifically, with a backbone of ResNet-18, our detector achieves an F-measure of 82.8, running at 62 FPS, on the MSRA-TD500 dataset. + +

Fusion](https://arxiv.org/abs/2202.10304) + + + +## Abstract + +Recently, segmentation-based scene text detection methods have drawn extensive attention in the scene text detection field, because of their superiority in detecting the text instances of arbitrary shapes and extreme aspect ratios, profiting from the pixel-level descriptions. However, the vast majority of the existing segmentation-based approaches are limited to their complex post-processing algorithms and the scale robustness of their segmentation models, where the post-processing algorithms are not only isolated to the model optimization but also time-consuming and the scale robustness is usually strengthened by fusing multi-scale feature maps directly. In this paper, we propose a Differentiable Binarization (DB) module that integrates the binarization process, one of the most important steps in the post-processing procedure, into a segmentation network. Optimized along with the proposed DB module, the segmentation network can produce more accurate results, which enhances the accuracy of text detection with a simple pipeline. Furthermore, an efficient Adaptive Scale Fusion (ASF) module is proposed to improve the scale robustness by fusing features of different scales adaptively. By incorporating the proposed DB and ASF with the segmentation network, our proposed scene text detector consistently achieves state-of-the-art results, in terms of both detection accuracy and speed, on five standard benchmarks. + +

reasoning graph network for arbitrary shape text detection](https://arxiv.org/abs/2003.07493) + + + +## Abstract + +Arbitrary shape text detection is a challenging task due to the high variety and complexity of scenes texts. In this paper, we propose a novel unified relational reasoning graph network for arbitrary shape text detection. In our method, an innovative local graph bridges a text proposal model via Convolutional Neural Network (CNN) and a deep relational reasoning network via Graph Convolutional Network (GCN), making our network end-to-end trainable. To be concrete, every text instance will be divided into a series of small rectangular components, and the geometry attributes (e.g., height, width, and orientation) of the small components will be estimated by our text proposal model. Given the geometry attributes, the local graph construction model can roughly establish linkages between different text components. For further reasoning and deducing the likelihood of linkages between the component and its neighbors, we adopt a graph-based network to perform deep relational reasoning on local graphs. Experiments on public available datasets demonstrate the state-of-the-art performance of our method. + +

Most of existing methods model text instances in image spatial domain via masks or contour point sequences in the Cartesian or the polar coordinate system. However, the mask representation might lead to expensive post-processing, while the point sequence one may have limited capability to model texts with highly-curved shapes. To tackle these problems, we model text instances in the Fourier domain and propose one novel Fourier Contour Embedding (FCE) method to represent arbitrary shaped text contours as compact signatures. We further construct FCENet with a backbone, feature pyramid networks (FPN) and a simple post-processing with the Inverse Fourier Transformation (IFT) and Non-Maximum Suppression (NMS). Different from previous methods, FCENet first predicts compact Fourier signatures of text instances, and then reconstructs text contours via IFT and NMS during test. Extensive experiments demonstrate that FCE is accurate and robust to fit contours of scene texts even with highly-curved shapes, and also validate the effectiveness and the good generalization of FCENet for arbitrary-shaped text detection. Furthermore, experimental results show that our FCENet is superior to the state-of-the-art (SOTA) methods on CTW1500 and Total-Text, especially on challenging highly-curved text subset. + +

and general framework for object instance segmentation. Our approach efficiently detects objects in an image while simultaneously generating a high-quality segmentation mask for each instance. The method, called Mask R-CNN, extends Faster R-CNN by adding a branch for predicting an object mask in parallel with the existing branch for bounding box recognition. Mask R-CNN is simple to train and adds only a small overhead to Faster R-CNN, running at 5 fps. Moreover, Mask R-CNN is easy to generalize to other tasks, e.g., allowing us to estimate human poses in the same framework. We show top results in all three tracks of the COCO suite of challenges, including instance segmentation, bounding-box object detection, and person keypoint detection. Without bells and whistles, Mask R-CNN outperforms all existing, single-model entries on every task, including the COCO 2016 challenge winners. We hope our simple and effective approach will serve as a solid baseline and help ease future research in instance-level recognition. + +

Accurate Arbitrary-Shaped Text Detection with Pixel Aggregation Network](https://arxiv.org/abs/1908.05900) + + + +## Abstract + +Scene text detection, an important step of scene text reading systems, has witnessed rapid development with convolutional neural networks. Nonetheless, two main challenges still exist and hamper its deployment to real-world applications. The first problem is the trade-off between speed and accuracy. The second one is to model the arbitrary-shaped text instance. Recently, some methods have been proposed to tackle arbitrary-shaped text detection, but they rarely take the speed of the entire pipeline into consideration, which may fall short in practical this http URL this paper, we propose an efficient and accurate arbitrary-shaped text detector, termed Pixel Aggregation Network (PAN), which is equipped with a low computational-cost segmentation head and a learnable post-processing. More specifically, the segmentation head is made up of Feature Pyramid Enhancement Module (FPEM) and Feature Fusion Module (FFM). FPEM is a cascadable U-shaped module, which can introduce multi-level information to guide the better segmentation. FFM can gather the features given by the FPEMs of different depths into a final feature for segmentation. The learnable post-processing is implemented by Pixel Aggregation (PA), which can precisely aggregate text pixels by predicted similarity vectors. Experiments on several standard benchmarks validate the superiority of the proposed PAN. It is worth noting that our method can achieve a competitive F-measure of 79.9% at 84.2 FPS on CTW1500. + +

However, there still exists two challenges which prevent the algorithm into industry applications. On the one hand, most of the state-of-art algorithms require quadrangle bounding box which is in-accurate to locate the texts with arbitrary shape. On the other hand, two text instances which are close to each other may lead to a false detection which covers both instances. Traditionally, the segmentation-based approach can relieve the first problem but usually fail to solve the second challenge. To address these two challenges, in this paper, we propose a novel Progressive Scale Expansion Network (PSENet), which can precisely detect text instances with arbitrary shapes. More specifically, PSENet generates the different scale of kernels for each text instance, and gradually expands the minimal scale kernel to the text instance with the complete shape. Due to the fact that there are large geometrical margins among the minimal scale kernels, our method is effective to split the close text instances, making it easier to use segmentation-based methods to detect arbitrary-shaped text instances. Extensive experiments on CTW1500, Total-Text, ICDAR 2015 and ICDAR 2017 MLT validate the effectiveness of PSENet. Notably, on CTW1500, a dataset full of long curve texts, PSENet achieves a F-measure of 74.3% at 27 FPS, and our best F-measure (82.2%) outperforms state-of-art algorithms by 6.6%. The code will be released in the future. + +

A Flexible Representation for Detecting Text of Arbitrary Shapes](https://arxiv.org/abs/1807.01544) + + + +## Abstract + +Driven by deep neural networks and large scale datasets, scene text detection methods have progressed substantially over the past years, continuously refreshing the performance records on various standard benchmarks. However, limited by the representations (axis-aligned rectangles, rotated rectangles or quadrangles) adopted to describe text, existing methods may fall short when dealing with much more free-form text instances, such as curved text, which are actually very common in real-world scenarios. To tackle this problem, we propose a more flexible representation for scene text, termed as TextSnake, which is able to effectively represent text instances in horizontal, oriented and curved forms. In TextSnake, a text instance is described as a sequence of ordered, overlapping disks centered at symmetric axes, each of which is associated with potentially variable radius and orientation. Such geometry attributes are estimated via a Fully Convolutional Network (FCN) model. In experiments, the text detector based on TextSnake achieves state-of-the-art or comparable performance on Total-Text and SCUT-CTW1500, the two newly published benchmarks with special emphasis on curved text in natural images, as well as the widely-used datasets ICDAR 2015 and MSRA-TD500. Specifically, TextSnake outperforms the baseline on Total-Text by more than 40% in F-measure. + +

ABINet + +> [Read Like Humans: Autonomous, Bidirectional and Iterative Language Modeling for Scene Text Recognition](https://arxiv.org/abs/2103.06495) + + + +## Abstract + +Linguistic knowledge is of great benefit to scene text recognition. However, how to effectively model linguistic rules in end-to-end deep networks remains a research challenge. In this paper, we argue that the limited capacity of language models comes from: 1) implicitly language modeling; 2) unidirectional feature representation; and 3) language model with noise input. Correspondingly, we propose an autonomous, bidirectional and iterative ABINet for scene text recognition. Firstly, the autonomous suggests to block gradient flow between vision and language models to enforce explicitly language modeling. Secondly, a novel bidirectional cloze network (BCN) as the language model is proposed based on bidirectional feature representation. Thirdly, we propose an execution manner of iterative correction for language model which can effectively alleviate the impact of noise input. Additionally, based on the ensemble of iterative predictions, we propose a self-training method which can learn from unlabeled images effectively. Extensive experiments indicate that ABINet has superiority on low-quality images and achieves state-of-the-art results on several mainstream benchmarks. Besides, the ABINet trained with ensemble self-training shows promising improvement in realizing human-level recognition. + +

In particular, perspective text and curved text are common in natural scenes and are difficult to recognize. In this work, we introduce ASTER, an end-to-end neural network model that comprises a rectification network and a recognition network. The rectification network adaptively transforms an input image into a new one, rectifying the text in it. It is powered by a flexible Thin-Plate Spline transformation which handles a variety of text irregularities and is trained without human annotations. The recognition network is an attentional sequence-to-sequence model that predicts a character sequence directly from the rectified image. The whole model is trained end to end, requiring only images and their groundtruth text. Through extensive experiments, we verify the effectiveness of the rectification and demonstrate the state-of-the-art recognition performance of ASTER. Furthermore, we demonstrate that ASTER is a powerful component in end-to-end recognition systems, for its ability to enhance the detector. + +

In this paper, we investigate the problem of scene text recognition, which is among the most important and challenging tasks in image-based sequence recognition. A novel neural network architecture, which integrates feature extraction, sequence modeling and transcription into a unified framework, is proposed. Compared with previous systems for scene text recognition, the proposed architecture possesses four distinctive properties: (1) It is end-to-end trainable, in contrast to most of the existing algorithms whose components are separately trained and tuned. (2) It naturally handles sequences in arbitrary lengths, involving no character segmentation or horizontal scale normalization. (3) It is not confined to any predefined lexicon and achieves remarkable performances in both lexicon-free and lexicon-based scene text recognition tasks. (4) It generates an effective yet much smaller model, which is more practical for real-world application scenarios. The experiments on standard benchmarks, including the IIIT-5K, Street View Text and ICDAR datasets, demonstrate the superiority of the proposed algorithm over the prior arts. Moreover, the proposed algorithm performs well in the task of image-based music score recognition, which evidently verifies the generality of it. + +

However, such methods suffer from attention-drift problem because high similarity among encoded features leads to attention confusion under the RNN-based local attention mechanism. Moreover, RNN-based methods have low efficiency due to poor parallelization. To overcome these problems, we propose the MASTER, a self-attention based scene text recognizer that (1) not only encodes the input-output attention but also learns self-attention which encodes feature-feature and target-target relationships inside the encoder and decoder and (2) learns a more powerful and robust intermediate representation to spatial distortion, and (3) owns a great training efficiency because of high training parallelization and a high-speed inference because of an efficient memory-cache mechanism.

Existing methods mainly adopt recurrence or convolution based networks. Though have obtained good performance, these methods still suffer from two limitations: slow training speed due to the internal recurrence of RNNs, and high complexity due to stacked convolutional layers for long-term feature extraction. This paper, for the first time, proposes a no-recurrence sequence-to-sequence text recognizer, named NRTR, that dispenses with recurrences and convolutions entirely. NRTR follows the encoder-decoder paradigm, where the encoder uses stacked self-attention to extract image features, and the decoder applies stacked self-attention to recognize texts based on encoder output. NRTR relies solely on self-attention mechanism thus could be trained with more parallelization and less complexity. Considering scene image has large variation in text and background, we further design a modality-transform block to effectively transform 2D input images to 1D sequences, combined with the encoder to extract more discriminative features. NRTR achieves state-of-the-art or highly competitive performance on both regular and irregular benchmarks, while requires only a small fraction of training time compared to the best model from the literature (at least 8 times faster). + +

However, it performs poorly on contextless texts (e.g., random character sequences) which is unacceptable in most of real application scenarios. In this paper, we first deeply investigate the decoding process of the decoder. We empirically find that a representative character-level sequence decoder utilizes not only context information but also positional information. Contextual information, which the existing approaches heavily rely on, causes the problem of attention drift. To suppress such side-effect, we propose a novel position enhancement branch, and dynamically fuse its outputs with those of the decoder attention module for scene text recognition. Specifically, it contains a position aware module to enable the encoder to output feature vectors encoding their own spatial positions, and an attention module to estimate glimpses using the positional clue (i.e., the current decoding time step) only. The dynamic fusion is conducted for more robust feature via an element-wise gate mechanism. Theoretically, our proposed method, dubbed \\emph{RobustScanner}, decodes individual characters with dynamic ratio between context and positional clues, and utilizes more positional ones when the decoding sequences with scarce context, and thus is robust and practical. Empirically, it has achieved new state-of-the-art results on popular regular and irregular text recognition benchmarks while without much performance drop on contextless benchmarks, validating its robustness in both contextual and contextless application scenarios. + +

In this work, we propose an easy-to-implement strong baseline for irregular scene text recognition, using off-the-shelf neural network components and only word-level annotations. It is composed of a 31-layer ResNet, an LSTM-based encoder-decoder framework and a 2-dimensional attention module.

While there have been great advances in STR methods, current methods still fail to recognize texts in arbitrary shapes, such as heavily curved or rotated texts, which are abundant in daily life (e.g. restaurant signs, product labels, company logos, etc). This paper introduces a novel architecture to recognizing texts of arbitrary shapes, named Self-Attention Text Recognition Network (SATRN), which is inspired by the Transformer. SATRN utilizes the self-attention mechanism to describe two-dimensional (2D) spatial dependencies of characters in a scene text image. Exploiting the full-graph propagation of self-attention, SATRN can recognize texts with arbitrary arrangements and large inter-character spacing. As a result, SATRN outperforms existing STR models by a large margin of 5.7 pp on average in "irregular text" benchmarks. We provide empirical analyses that illustrate the inner mechanisms and the extent to which the model is applicable (e.g. rotated and multi-line text). We will open-source the code. + +

This hybrid architecture, although accurate, is complex and less efficient. In this study, we propose a Single Visual model for Scene Text recognition within the patch-wise image tokenization framework, which dispenses with the sequential modeling entirely. The method, termed SVTR, firstly decomposes an image text into small patches named character components. Afterward, hierarchical stages are recurrently carried out by component-level mixing, merging and/or combining. Global and local mixing blocks are devised to perceive the inter-character and intra-character patterns, leading to a multi-grained character component perception. Thus, characters are recognized by a simple linear prediction. Experimental results on both English and Chinese scene text recognition tasks demonstrate the effectiveness of SVTR. SVTR-L (Large) achieves highly competitive accuracy in English and outperforms existing methods by a large margin in Chinese, while running faster. In addition, SVTR-T (Tiny) is an effective and much smaller model, which shows appealing speed at inference. + +

+In MMOCR, all the datasets are processed via different Dataset classes based on [mmengine.BaseDataset](mmengine.dataset.BaseDataset). Dataset classes are responsible for loading the data and performing initial parsing, then fed to [data pipeline](./transforms.md) for data preprocessing, augmentation, formatting, etc. + +
+ +![Flowchart](https://user-images.githubusercontent.com/22607038/225302639-c65888c5-cda0-4df7-ac79-1348fe16d44a.png) + +
+ +In this tutorial, we will introduce some common interfaces of the Dataset class, and the usage of Dataset implementations in MMOCR as well as the annotation types they support. + +```{tip} +Dataset class supports some advanced features, such as lazy initialization and data serialization, and takes advantage of various dataset wrappers to perform data concatenation, repeating, and category balancing. These content will not be covered in this tutorial, but you can read {external+mmengine:doc}`MMEngine: BaseDataset ` for more details. +``` + +## Common Interfaces + +Now, let's look at a concrete example and learn some typical interfaces of a Dataset class. +`OCRDataset` is a widely used Dataset implementation in MMOCR, and is suggested as a default Dataset type in MMOCR as its associated annotation format is flexible enough to support *all* the OCR tasks ([more info](#ocrdataset)). Now we will instantiate an `OCRDataset` object wherein the toy dataset in `tests/data/det_toy_dataset` will be loaded. + +```python +from mmocr.datasets import OCRDataset +from mmengine.registry import init_default_scope +init_default_scope('mmocr') + +train_pipeline = [ + dict( + type='LoadImageFromFile'), + dict( + type='LoadOCRAnnotations', + with_polygon=True, + with_bbox=True, + with_label=True, + ), + dict(type='RandomCrop', min_side_ratio=0.1), + dict(type='Resize', scale=(640, 640), keep_ratio=True), + dict(type='Pad', size=(640, 640)), + dict( + type='PackTextDetInputs', + meta_keys=('img_path', 'ori_shape', 'img_shape')) +] +dataset = OCRDataset( + data_root='tests/data/det_toy_dataset', + ann_file='textdet_test.json', + test_mode=False, + pipeline=train_pipeline) + +``` + +Let's peek the size of this dataset: + +```python +>>> print(len(dataset)) + +10 +``` + +Typically, a Dataset class loads and stores two types of information: (1) **meta information**: Some meta descriptors of the dataset's property, such as available object categories in this dataset. (2) **annotation**: The path to images, and their labels. We can access the meta information in `dataset.metainfo`: + +```python +>>> from pprint import pprint +>>> pprint(dataset.metainfo) + +{'category': [{'id': 0, 'name': 'text'}], + 'dataset_type': 'TextDetDataset', + 'task_name': 'textdet'} +``` + +As for the annotations, we can access them via `dataset.get_data_info(idx)`, which returns a dictionary containing the information of the `idx`-th sample in the dataset that is initially parsed, but not yet processed by [data pipeline](./transforms.md). + +```python +>>> from pprint import pprint +>>> pprint(dataset.get_data_info(0)) + +{'height': 720, + 'img_path': 'tests/data/det_toy_dataset/test/img_10.jpg', + 'instances': [{'bbox': [260.0, 138.0, 284.0, 158.0], + 'bbox_label': 0, + 'ignore': True, + 'polygon': [261, 138, 284, 140, 279, 158, 260, 158]}, + ..., + {'bbox': [1011.0, 157.0, 1079.0, 173.0], + 'bbox_label': 0, + 'ignore': True, + 'polygon': [1011, 157, 1079, 160, 1076, 173, 1011, 170]}], + 'sample_idx': 0, + 'seg_map': 'test/gt_img_10.txt', + 'width': 1280} + +``` + +On the other hand, we can get the sample fully processed by data pipeline via `dataset[idx]` or `dataset.__getitem__(idx)`, which is directly feedable to models and perform a full train/test cycle. It has two fields: + +- `inputs`: The image after data augmentation; +- `data_samples`: The [DataSample](./structures.md) that contains the augmented annotations, and meta information appended by some data transforms to keep track of some key properties of this sample. + +```python +>>> pprint(dataset[0]) + +{'data_samples': +) at 0x7f735a0508e0>, + 'inputs': tensor([[[129, 111, 131, ..., 0, 0, 0], ... + [ 19, 18, 15, ..., 0, 0, 0]]], dtype=torch.uint8)} +``` + +## Dataset Classes and Annotation Formats + +Each Dataset implementation can only load datasets in a specific annotation format. Here lists all supported Dataset classes and their compatible annotation formats, as well as an example config that showcases how to use them in practice. + +```{note} +If you are not familiar with the config system, you may find [Dataset Configuration](../user_guides/dataset_prepare.md#dataset-configuration) helpful. +``` + +### OCRDataset + +Usually, there are many different types of annotations in OCR datasets, and the formats often vary between different subtasks, such as text detection and text recognition. These differences can result in the need for different data loading code when using different datasets, increasing the learning and maintenance costs for users. + +In MMOCR, we propose a unified dataset format that can adapt to all three subtasks of OCR: text detection, text recognition, and text spotting. This design maximizes the uniformity of the dataset, allows for the reuse of data annotations across different tasks, and makes dataset management more convenient. Considering that popular dataset formats are still inconsistent, MMOCR provides [Dataset Preparer](../user_guides/data_prepare/dataset_preparer.md) to help users convert their datasets to MMOCR format. We also strongly encourage researchers to develop their own datasets based on this data format. + +#### Annotation Format + +This annotation file is a `.json` file that stores a `dict`, containing both `metainfo` and `data_list`, where the former includes basic information about the dataset and the latter consists of the label item of each target instance. Here presents an extensive list of all the fields in the annotation file, but some fields are used in a subset of tasks and can be ignored in other tasks. + +```python +{ + "metainfo": + { + "dataset_type": "TextDetDataset", # Options: TextDetDataset/TextRecogDataset/TextSpotterDataset + "task_name": "textdet", # Options: textdet/textspotter/textrecog + "category": [{"id": 0, "name": "text"}] # Used in textdet/textspotter + }, + "data_list": + [ + { + "img_path": "test_img.jpg", + "height": 604, + "width": 640, + "instances": # multiple instances in one image + [ + { + "bbox": [0, 0, 10, 20], # in textdet/textspotter, [x1, y1, x2, y2]. + "bbox_label": 0, # The object category, always 0 (text) in MMOCR + "polygon": [0, 0, 0, 10, 10, 20, 20, 0], # in textdet/textspotter. [x1, y1, x2, y2, ....] + "text": "mmocr", # in textspotter/textrecog + "ignore": False # in textspotter/textdet. Whether to ignore this sample during training + }, + #... + ], + } + #... multiple images + ] +} +``` + +#### Example Config + +Here is a part of config example where we make `train_dataloader` use `OCRDataset` to load the ICDAR2015 dataset for a text detection model. Keep in mind that `OCRDataset` can load any OCR datasets prepared by Dataset Preparer regardless of its task. That is, you can use it for text recognition and text spotting, but you still have to modify the transform types in `pipeline` according to the needs of different tasks. + +```python +pipeline = [ + dict( + type='LoadImageFromFile'), + dict( + type='LoadOCRAnnotations', + with_polygon=True, + with_bbox=True, + with_label=True, + ), + dict( + type='PackTextDetInputs', + meta_keys=('img_path', 'ori_shape', 'img_shape')) +] + +icdar2015_textdet_train = dict( + type='OCRDataset', + data_root='data/icdar2015', + ann_file='textdet_train.json', + filter_cfg=dict(filter_empty_gt=True, min_size=32), + pipeline=pipeline) + +train_dataloader = dict( + batch_size=16, + num_workers=8, + persistent_workers=True, + sampler=dict(type='DefaultSampler', shuffle=True), + dataset=icdar2015_textdet_train) +``` + +### RecogLMDBDataset + +Reading images or labels from files can be slow when data are excessive, e.g. on a scale of millions. Besides, in academia, most of the scene text recognition datasets are stored in lmdb format, including images and labels.

Users usually do not need to understand or manually modify the internal implementation of the evaluation metric. However, to facilitate more customized requirements, this document will further introduce the specific implementation details and configurable parameters of the built-in metrics in MMOCR. + +### HmeanIOUMetric + +[HmeanIOUMetric](mmocr.evaluation.metrics.hmean_iou_metric.HmeanIOUMetric) is one of the most widely used evaluation metrics in text detection tasks, because it calculates the harmonic mean (H-mean) between the detection precision (P) and recall rate (R). The `HmeanIOUMetric` can be calculated by the following equation: + +```{math} +H = \frac{2}{\frac{1}{P} + \frac{1}{R}} = \frac{2PR}{P+R} +``` + +In addition, since it is equivalent to the F-score (also known as F-measure or F-metric) when {math}`\beta = 1`, `HmeanIOUMetric` is sometimes written as `F1Metric` or `f1-score`: + +```{math} +F_1=(1+\beta^2)\cdot\frac{PR}{\beta^2\cdot P+R} = \frac{2PR}{P+R} +``` + +In MMOCR, the calculation of `HmeanIOUMetric` can be summarized as the following steps: + +1. Filter out invalid predictions + + - Filter out predictions with a score is lower than `pred_score_thrs` + - Filter out predictions overlapping with `ignored` ground truth boxes with an overlap ratio higher than `ignore_precision_thr` + + It is worth noting that `pred_score_thrs` will **automatically search** for the **best threshold** within a certain range by default, and users can also customize the search range by manually modifying the configuration file: + + ```python + # By default, HmeanIOUMetric searches the best threshold within the range [0.3, 0.9] with a step size of 0.1 + val_evaluator = dict(type='HmeanIOUMetric', pred_score_thrs=dict(start=0.3, stop=0.9, step=0.1)) + ``` + +2. Calculate the IoU matrix + + - At the data processing stage, `HmeanIOUMetric` will calculate and maintain an {math}`M \times N` IoU matrix `iou_metric` for the convenience of the subsequent bounding box pairing step. Here, M and N represent the number of label bounding boxes and filtered prediction bounding boxes, respectively. Therefore, each element of this matrix stores the IoU between the m-th label bounding box and the n-th prediction bounding box. + +3. Compute the number of GT samples that can be accurately matched based on the corresponding pairing strategy + + Although `HmeanIOUMetric` can be calculated by a fixed formula, there may still be some subtle differences in the specific implementations. These differences mainly reflect the use of different strategies to match gt and predicted bounding boxes, which leads to the difference in final scores. Currently, MMOCR supports two matching strategies, namely `vanilla` and `max_matching`, for the `HmeanIOUMetric`. As shown below, users can specify the matching strategies in the config. + + - `vanilla` matching strategy + + By default, `HmeanIOUMetric` adopts the `vanilla` matching strategy, which is consistent with the `hmean-iou` implementation in MMOCR 0.x and the **official** text detection competition evaluation standard of ICDAR series. The matching strategy adopts the first-come-first-served matching method to pair the labels and predictions. + + ```python + # By default, HmeanIOUMetric adopts 'vanilla' matching strategy + val_evaluator = dict(type='HmeanIOUMetric') + ``` + + - `max_matching` matching strategy + + To address the shortcomings of the existing matching mechanism, MMOCR has implemented a more efficient matching strategy to maximize the number of matches. + + ```python + # Specify to use 'max_matching' matching strategy + val_evaluator = dict(type='HmeanIOUMetric', strategy='max_matching') + ``` + + ```{note} + We recommend that research-oriented developers use the default `vanilla` matching strategy to ensure consistency with other papers. For industry-oriented developers, you can use the `max_matching` matching strategy to achieve optimized performance. + ``` + +4. Compute the final evaluation score according to the aforementioned matching strategy + +### WordMetric + +[WordMetric](mmocr.evaluation.metrics.recog_metric.WordMetric) implements **word-level** text recognition evaluation metrics and includes three text matching modes, namely `exact`, `ignore_case`, and `ignore_case_symbol`. Users can freely combine the output of one or more text matching modes in the configuration file by modifying the `mode` field. + +```python +# Use WordMetric for text recognition task +val_evaluator = [ + dict(type='WordMetric', mode=['exact', 'ignore_case', 'ignore_case_symbol']) +] +``` + +- `exact`๏ผšFull matching mode, i.e., only when the predicted text and the ground truth text are exactly the same, the predicted text is considered to be correct. +- `ignore_case`๏ผšThe mode ignores the case of the predicted text and the ground truth text. +- `ignore_case_symbol`๏ผšThe mode ignores the case and symbols of the predicted text and the ground truth text. This is also the text recognition accuracy reported by most academic papers. The performance reported by MMOCR uses the `ignore_case_symbol` mode by default. + +Assume that the real label is `MMOCR!` and the model output is `mmocr`. The `WordMetric` scores under the three matching modes are: `{'exact': 0, 'ignore_case': 0, 'ignore_case_symbol': 1}`. + +### CharMetric + +[CharMetric](mmocr.evaluation.metrics.recog_metric.CharMetric) implements **character-level** text recognition evaluation metrics that are **case-insensitive**. + +```python +# Use CharMetric for text recognition task +val_evaluator = [dict(type='CharMetric')] +``` + +Specifically, `CharMetric` will output two evaluation metrics, namely `char_precision` and `char_recall`. Let the number of correctly predicted characters (True Positive) be {math}`\sigma_{tp}`, then the precision *P* and recall *R* can be calculated by the following equation: + +```{math} +P=\frac{\sigma_{tp}}{\sigma_{pred}}, R = \frac{\sigma_{tp}}{\sigma_{gt}} +``` + +where {math}`\sigma_{gt}` and {math}`\sigma_{pred}` represent the total number of characters in the label text and the predicted text, respectively. + +For example, assume that the label text is "MM**O**CR" and the predicted text is "mm**0**cR**1**". The score of the `CharMetric` is: + +```{math} +P=\frac{4}{6}, R=\frac{4}{5} +``` + +### OneMinusNEDMetric + +[OneMinusNEDMetric(1-N.E.D)](mmocr.evaluation.metrics.recog_metric.OneMinusNEDMetric) is commonly used for text recognition evaluation of Chinese or English **text line-level** annotations. Unlike the full matching metric that requires the prediction and the gt text to be exactly the same, `1-N.E.D` uses the normalized [edit distance](https://en.wikipedia.org/wiki/Edit_distance) (also known as Levenshtein Distance) to measure the difference between the predicted and the gt text, so that the performance difference of the model can be better distinguished when evaluating long texts. Assume that the real and predicted texts are {math}`s_i` and {math}`\hat{s_i}`, respectively, and their lengths are {math}`l_{i}` and {math}`\hat{l_i}`, respectively. The `OneMinusNEDMetric` score can be calculated by the following formula: + +```{math} +score = 1 - \frac{1}{N}\sum_{i=1}^{N}\frac{D(s_i, \hat{s_{i}})}{max(l_{i},\hat{l_{i}})} +``` + +where *N* is the total number of samples, and {math}`D(s_1, s_2)` is the edit distance between two strings. + +For example, assume that the real label is "OpenMMLabMMOCR", the prediction of model A is "0penMMLabMMOCR", and the prediction of model B is "uvwxyz". The results of the full matching and `OneMinusNEDMetric` evaluation metrics are as follows: + +| | | | +| ------- | ---------- | ---------- | +| | Full-match | 1 - N.E.D. | +| Model A | 0 | 0.92857 | +| Model B | 0 | 0 | + +As shown in the table above, although the model A only predicted one letter incorrectly, both models got 0 in when using full-match strategy. However, the `OneMinusNEDMetric` evaluation metric can better distinguish the performance of the two models on **long texts**. + +### F1Metric + +[F1Metric](mmocr.evaluation.metrics.f_metric.F1Metric) implements the F1-Metric evaluation metric for KIE tasks and provides two modes, namely `micro` and `macro`. + +```python +val_evaluator = [ + dict(type='F1Metric', mode=['micro', 'macro'], +] +``` + +- `micro` mode: Calculate the global F1-Metric score based on the total number of True Positive, False Negative, and False Positive. + +- `macro` mode๏ผšCalculate the F1-Metric score for each class and then take the average. + +### Customized Metric + +MMOCR supports the implementation of customized evaluation metrics for users who pursue higher customization. In general, users only need to create a customized evaluation metric class `CustomizedMetric` and inherit {external+mmengine:doc}`MMEngine: BaseMetric `. Then, the data format processing method `process` and the metric calculation method `compute_metrics` need to be overwritten respectively. Finally, add it to the `METRICS` registry to implement any customized evaluation metric. + +```python +from mmengine.evaluator import BaseMetric +from mmocr.registry import METRICS + +@METRICS.register_module() +class CustomizedMetric(BaseMetric): + + def process(self, data_batch: Sequence[Dict], predictions: Sequence[Dict]): + """ process receives two parameters, data_batch stores the gt label information, and predictions stores the predicted results. + """ + pass + + def compute_metrics(self, results: List): + """ compute_metric receives the results of the process method as input and returns the evaluation results. + """ + pass +``` + +```{note} +More details can be found in {external+mmengine:doc}`MMEngine Documentation: BaseMetric `. +``` diff --git a/pipeline/mmocr/docs/en/basic_concepts/models.md b/pipeline/mmocr/docs/en/basic_concepts/models.md new file mode 100644 index 0000000000000000000000000000000000000000..7eab561e7276af01c63ca7ae8c1452c5c6317c25 --- /dev/null +++ b/pipeline/mmocr/docs/en/basic_concepts/models.md @@ -0,0 +1,3 @@ +# Models\[coming soon\] + +Coming Soon! diff --git a/pipeline/mmocr/docs/en/basic_concepts/overview.md b/pipeline/mmocr/docs/en/basic_concepts/overview.md new file mode 100644 index 0000000000000000000000000000000000000000..9e31fefa5fc8cc9e7f86be30b18f0b62aa1c85d5 --- /dev/null +++ b/pipeline/mmocr/docs/en/basic_concepts/overview.md @@ -0,0 +1,3 @@ +# Overview & Features\[coming soon\] + +Coming Soon! diff --git a/pipeline/mmocr/docs/en/basic_concepts/structures.md b/pipeline/mmocr/docs/en/basic_concepts/structures.md new file mode 100644 index 0000000000000000000000000000000000000000..0f73a77286457a4f1360fcb8cd83353202ea786d --- /dev/null +++ b/pipeline/mmocr/docs/en/basic_concepts/structures.md @@ -0,0 +1,219 @@ +# Data Structures and Elements + +MMOCR uses {external+mmengine:doc}`MMEngine: Abstract Data Element ` to encapsulate the data required for each task into `data_sample`.

Next, we will briefly introduce the data transforms supported in MMOCR according to their categories. +``` + +For each data transform, MMOCR provides a detailed docstring. For example, in the header of each data transform class, we annotate `Required Keys`, `Modified Keys` and `Added Keys`. The `Required Keys` represent the mandatory fields that should be included in the input required by the data transform, while the `Modified Keys` and `Added Keys` indicate that the transform may modify or add the fields into the original data. For example, `LoadImageFromFile` implements the image loading function, whose `Required Keys` is the image path `img_path`, and the `Modified Keys` includes the loaded image `img`, the current size of the image `img_shape`, the original size of the image `ori_shape`, and other image attributes. + +```python +@TRANSFORMS.register_module() +class LoadImageFromFile(MMCV_LoadImageFromFile): + # We provide detailed docstring for each data transform. + """Load an image from file. + + Required Keys: + + - img_path + + Modified Keys: + + - img + - img_shape + - ori_shape + """ +``` + +```{note} +In the data pipeline of MMOCR, the image and label information are saved in a dictionary. By using the unified fields, the data can be freely transferred between different data transforms. Therefore, it is very important to understand the conventional fields used in MMOCR. +``` + +For your convenience, the following table lists the conventional keys used in MMOCR data transforms. + +| | | | +| ---------------- | --------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------- | +| Key | Type | Description | +| img | `np.array(dtype=np.uint8)` | Image array, shape of `(h, w, c)`. | +| img_shape | `tuple(int, int)` | Current image size `(h, w)`. | +| ori_shape | `tuple(int, int)` | Original image size `(h, w)`. | +| scale | `tuple(int, int)` | Stores the target image size `(h, w)` specified by the user in the `Resize` data transform series.

It occurs because the backbone network is pretrained on image classification tasks, where the last fc layer is required to generate the classification output. However, the fc layer is no longer needed when the backbone network is used to extract features in downstream tasks, and therefore these weights can be safely skipped when loading the checkpoint. + +**Q2** MMOCR terminates with an error: `shapely.errors.TopologicalError: The operation 'GEOSIntersection_r' could not be performed. Likely cause is invalidity of the geometry`. How could I fix it? + +**A** This error occurs because of some invalid polygons (e.g., polygons with self-intersections) existing in the dataset or generated by some non-rigorous data transforms. These polygons can be fixed by adding `FixInvalidPolygon` transform after the transform likely to introduce invalid polygons. For example, a common practice is to append it after `LoadOCRAnnotations` in both train and test pipeline. The resulting pipeline should look like: + +```python +train_pipeline = [ + ... + dict( + type='LoadOCRAnnotations', + with_polygon=True, + with_bbox=True, + with_label=True, + ), + dict(type='FixInvalidPolygon', min_poly_points=4), + ... +] +``` + +In practice, we find that Totaltext contains some invalid polygons and using `FixInvalidPolygon` is a must.

For example, if you want to train SAR model (https://github.com/open-mmlab/mmocr/blob/75c06d34bbc01d3d11dfd7afc098b6cdeee82579/configs/textrecog/sar/sar_resnet31_parallel-decoder_5e_st-sub_mj-sub_sa_real.py) with your own dictionary placed at `/my/dict.txt`, you can modify `dictionary.dict_file` term in [base config](https://github.com/open-mmlab/mmocr/blob/75c06d34bbc01d3d11dfd7afc098b6cdeee82579/configs/textrecog/sar/_base_sar_resnet31_parallel-decoder.py#L1) to: + +```python +dictionary = dict( + type='Dictionary', + dict_file='/my/dict.txt', + with_start=True, + with_end=True, + same_start_end=True, + with_padding=True, + with_unknown=True) +``` + +Now you are good to go.

In the next section, we will take you through the basic functions of MMOCR by training DBNet on the mini [ICDAR 2015](https://rrc.cvc.uab.es/?ch=4&com=downloads) dataset as an example. + +## Prepare a Dataset + +Since the variety of OCR dataset formats are not conducive to either switching or joint training of multiple datasets, MMOCR proposes a uniform [data format](../user_guides/dataset_prepare.md), and provides [dataset preparer](../user_guides/data_prepare/dataset_preparer.md) for commonly used OCR datasets. Usually, to use those datasets in MMOCR, you just need to follow the steps to get them ready for use. + +```{note} +But here, efficiency means everything. +``` + +Here, we have prepared a lite version of ICDAR 2015 dataset for demonstration purposes. Download our pre-prepared [zip](https://download.openmmlab.com/mmocr/data/icdar2015/mini_icdar2015.tar.gz) and extract it to the `data/` directory under mmocr to get our prepared image and annotation file. + +```Bash +wget https://download.openmmlab.com/mmocr/data/icdar2015/mini_icdar2015.tar.gz +mkdir -p data/ +tar xzvf mini_icdar2015.tar.gz -C data/ +``` + +## Modify the Config + +Once the dataset is prepared, we will then specify the location of the training set and the training parameters by modifying the config file. + +In this example, we will train a DBNet using resnet18 as its backbone. Since MMOCR already has a config file for the full ICDAR 2015 dataset (`configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py`), we just need to make some modifications on top of it. + +We first need to modify the path to the dataset. In this config, most of the key config files are imported in `_base_`, such as the database configuration from `configs/textdet/_base_/datasets/icdar2015.py`. Open that file and replace the path pointed to by `icdar2015_textdet_data_root` in the first line with: + +```Python +icdar2015_textdet_data_root = 'data/mini_icdar2015' +``` + +Also, because of the reduced dataset size, we have to reduce the number of training epochs to 400 accordingly, shorten the validation interval as well as the weight storage interval to 10 rounds, and drop the learning rate decay strategy. The following lines of configuration can be directly put into `configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py` to take effect. + +```Python +# Save checkpoints every 10 epochs, and only keep the latest checkpoint +default_hooks = dict( + checkpoint=dict( + type='CheckpointHook', + interval=10, + max_keep_ckpts=1, + )) +# Set the maximum number of epochs to 400, and validate the model every 10 epochs +train_cfg = dict(type='EpochBasedTrainLoop', max_epochs=400, val_interval=10) +# Fix learning rate as a constant +param_scheduler = [ + dict(type='ConstantLR', factor=1.0), +] +``` + +Here, we have rewritten the corresponding parameters in the base configuration directly through the inheritance ({external+mmengine:doc}`MMEngine: Config `) mechanism of the config. The original fields are distributed in `configs/textdet/_base_/schedules/schedule_sgd_1200e.py` and `configs/textdet/_base_/default_runtime.py`. + +```{note} +For a more detailed description of config, please refer to [here](../user_guides/config.md). +``` + +## Browse the Dataset + +Before we start the training, we can also visualize the image processed by training-time [data transforms](../basic_concepts/transforms.md). It's quite simple: pass the config file we need to visualize into the [browse_dataset.py](/tools/analysis_tools/browse_dataset.py) script. + +```Bash +python tools/analysis_tools/browse_dataset.py configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py +``` + +The transformed images and annotations will be displayed one by one in a pop-up window. + +

In this 1.0 release, MMOCR synchronizes its new model architecture to align as much as possible with the overall OpenMMLab design and to achieve structural uniformity within the algorithm library. Although this upgrade is not fully backward compatible, we summarize the changes that may be of interest to developers for those who need them. + +## Fundamental Changes + +Functional boundaries of modules has not been clearly defined in MMOCR 0.x. In MMOCR 1.0, we address this issue by refactoring the design of model modules. Here are some major changes in 1.0: + +- MMOCR 1.0 no longer supports named entity recognition tasks since it's not in the scope of OCR. + +- The module that computes the loss in a model is named as *Module Loss*, which is also responsible for the conversion of gold annotations into loss targets. Another module, *Postprocessor*, is responsible for decoding the model raw output into `DataSample` for the corresponding task at prediction time. + +- The inputs of all models are now organized as a dictionary that consists of two keys: `inputs`, containing the original features of the images, and `List[DataSample]`, containing the meta-information of the images. At training time, the output format of a model is standardized to a dictionary containing the loss tensors. Similarly, a model generates a sequence of `DataSample`s containing the prediction outputs in testing. + +- In MMOCR 0.x, the majority of classes named `XXLoss` have the implementations closely bound to the corresponding model, while their names made users hard to tell them apart from other generic losses like `DiceLoss`. In 1.0, they are renamed to the form `XXModuleLoss`. (e.g. `DBLoss` was renamed to `DBModuleLoss`). The key to their configurations in config files is also changed from `loss` to `module_loss`. + +- The names of generic loss classes that are not related to the model implementation are kept as `XXLoss`. (e.g. [`MaskedBCELoss`](mmocr.models.common.losses.MaskedBCELoss)) They are all placed under `mmocr/models/common/losses`. + +- Changes under `mmocr/models/common/losses`: `DiceLoss` is renamed to [`MaskedDiceLoss`](mmocr.models.common.losses.MaskedDiceLoss). `FocalLoss` has been removed. + +- MMOCR 1.0 adds a *Dictionary* module which originates from *label converter*. It is used in text recognition and key information extraction tasks. + +## Text Detection Models + +### Key Changes (TL;DR) + +- The model weights from MMOCR 0.x still works in the 1.0, but the fields starting with `bbox_head` in the state dict `state_dict` need to be renamed to `det_head`. + +- `XXTargets` transforms, which were responsible for genearting detection targets, have been merged into `XXModuleLoss`. + +### SingleStageTextDetector + +- The original inheritance chain was `mmdet.BaseDetector->SingleStageDetector->SingleStageTextDetector`. Now `SingleStageTextDetector` is directly inherited from `BaseDetector` without extra dependency on MMDetection, and `SingleStageDetector` is deleted. + +- `bbox_head` is renamed to `det_head`. + +- `train_cfg`, `test_cfg` and `pretrained` fields are removed. + +- `forward_train()` and `simple_test()` are refactored to `loss()` and `predict()`. The part of `simple_test()` that was responsible for splitting the raw output of the model and feeding it into `head.get_bounary()` is integrated into `BaseTextDetPostProcessor`. + +- `TextDetectorMixin` has been removed since its implementation overlaps with `TextDetLocalVisualizer`. + +### Head + +- `HeadMixin`, the base class that `XXXHead` had to inherit from in version 0.x, has been replaced by `BaseTextDetHead`. `get_boundary()` and `resize_boundary()` are now rewritten as `__call__()` and `rescale()` in `BaseTextDetPostProcessor`. + +### ModuleLoss + +- Data transforms `XXXTargets` in text detection tasks are all moved to `XXXModuleLoss._get_target_single()`. Target-related configurations are no longer specified in the data pipeline but in `XXXLoss` instead. + +### Postprocessor + +- The logic in the original `XXXPostprocessor.__call__()` are transferred to the refactored `XXXPostprocessor.get_text_instances()`. + +- `BasePostprocessor` is refactored to `BaseTextDetPostProcessor`. This base class splits and processes the model output predictions one by one and supports automatic scaling of the output polygon or bounding box based on `scale_factor`. + +## Text Recognition + +### Key Changes (TL;DR) + +- Due to the change of the character order and some bugs in the model architecture being fixed, the recognition model weights in 0.x can no longer be directly used in 1.0. We will provide a migration script and tutorial for those who need it. + +- The support of SegOCR has been removed. TPS-CRNN will still be supported in a later version. + +- Test time augmentation will be supported in the upcoming release. + +- *Label converter* module has been removed and its functions have been split into *Dictionary*, *ModuleLoss* and *Postprocessor*. + +- The definition of `max_seq_len` has been unified and now it represents the original output length of the model. + +### Label Converter + +- The original label converters had spelling errors (written as label convertors). We fixed them by removing label converters from this project. + +- The part responsible for converting characters/strings to and from numeric indexes was extracted to *Dictionary*. + +- In older versions, different label converters would have different special character sets and character order. In version 0.x, the character order was as follows. + +| Converter | Character order | +| ------------------------------- | ----------------------------------------- | +| `AttnConvertor`, `ABIConvertor` | ``, ``, ``, characters | +| `CTCConvertor` | ``, ``, characters | + +In 1.0, instead of designing different dictionaries and character orders for different tasks, we have a unified *Dictionary* implementation with the character order always as characters, \, \, \. \ in `CTCConvertor` has been equivalently replaced by \. + +- *Label convertor* originally supported three ways to initialize dictionaries: `dict_type`, `dict_file` and `dict_list`, which are now reduced to `dict_file` only in `Dictionary`. Also, we have put those pre-defined character sets originally supported in `dict_type` into `dicts/` directory now.

+ +7. `RandomScaling` -> [`mmengine.RandomResize`](mmcv.transforms.RandomResize) + + The `RandomScaling` is now replaced with [`mmengine.RandomResize`](mmcv.transforms.RandomResize). + + + + + + + + + + +
MMOCR 0.x ConfigurationMMOCR 1.x Configuration

+ +```{note} +By default, the data pipeline will search for the corresponding data transforms from the register of the current *scope*, and if that data transform does not exist, it will continue to search in the upstream library, such as MMCV and MMEngine. For example, the `RandomResize` transform is not implemented in MMOCR, but it can be directly called in the configuration, as the program will automatically search for it from MMCV. In addition, you can also specify *scope* by adding a prefix. For example, `mmengine.RandomResize` will force it to use `RandomResize` implemented in MMEngine, which is useful when a method of the same name exists in both upstream and downstream libraries. It is noteworthy that all of the data transforms implemented in MMCV are registered to MMEngine, that is why we use `mmengine.RandomResize` but not `mmcv.RandomResize`. +``` + +8. `SquareResizePad` -> [`Resize`](mmocr.datasets.transforms.Resize) + [`SourceImagePad`](mmocr.datasets.transforms.SourceImagePad) + + `SquareResizePad` implements two branches and uses one of them randomly based on the `pad_ratio`. Specifically, one branch first resizes the image and then pads it to a certain size; while the other branch only resizes the image. To enhance the reusability of the different modules, we split this data transform into a combination of `Resize` + `SourceImagePad` in version 1.x, and control the branches via `RandomChoice`. + + + + + + + + + + +

+ +```{note} +In version 1.x, the random choice wrapper "RandomChoice" replaces "OneOfWrapper", allowing random selection of data transform combinations. +``` + +9. `RandomWrapper` -> [`mmengine.RandomApply`](mmcv.transforms.RandomApply) + + In version 1.x, the `RandomWrapper` wrapper has been replaced with `RandomApply` in MMEngine, which is used to specify the probability of performing a data transform. And the probability `p` is now named `prob`. + + + + + + + + + + +

+ +10. `OneOfWrapper` -> [`mmengine.RandomChoice`](mmcv.transforms.RandomChoice) + + The random choice wrapper is now renamed to `RandomChoice` and is used in exactly the same way as before. + +11. `ScaleAspectJitter` -> [`ShortScaleAspectJitter`](mmocr.datasets.transforms.ShortScaleAspectJitter), [`BoundedScaleAspectJitter`](mmocr.datasets.transforms.BoundedScaleAspectJitter) + + The `ScaleAspectJitter` implemented several different image size jittering strategies, which has now been split into several independent data transforms. + + When `resize_type='indep_sample_in_range'`, it is equivalent to `RandomResize`. + + + + + + + + + + +

+ +When `resize_type='long_short_bound'`, we implemented `BoundedScaleAspectJitter`, which randomly rescales the image so that the long and short sides of the image are around the bound; then jitters the aspect ratio. + + + + + + + + + + +

+ +When `resize_type='round_min_img_scale'`, we implemented `ShortScaleAspectJitter`, which rescales the image for its shorter side to reach the `short_size` and then jitters its aspect ratio, finally rescales the shape guaranteed to be divided by scale_divisor. + + + + + + + + + + +

Dataset Preparer can automatically generate base dataset configs at the end of the preparation process, and supports 6 more datasets: IIIT5k, CUTE80, ICDAR2013, ICDAR2015, SVT, SVTP. +2. Introducing our `projects/` folder - implementing new models and features into OpenMMLab's algorithm libraries has long been complained to be troublesome due to the rigorous requirements on code quality, which could hinder the fast iteration of SOTA models and might discourage community members from sharing their latest outcome here. We now introduce `projects/` folder, where some experimental features, frameworks and models can be placed, only needed to satisfy the minimum requirement on the code quality. Everyone is welcome to post their implementation of any great ideas in this folder! We also add the first [example project](https://github.com/open-mmlab/mmocr/tree/dev-1.x/projects/example_project) to illustrate what we expect a good project to have (check out the raw content of README.md for more info!). +3. Inside the `projects/` folder, we are releasing the preview version of ABCNet, which is the first implementation of text spotting models in MMOCR. It's inference-only now, but the full implementation will be available very soon. + +### New Features & Enhancements + +- Add SVT to dataset preparer by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/1521 +- Polish bbox2poly by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1532 +- Add SVTP to dataset preparer by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/1523 +- Iiit5k converter by @Harold-lkk in https://github.com/open-mmlab/mmocr/pull/1530 +- Add cute80 to dataset preparer by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/1522 +- Add IC13 preparer by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/1531 +- Add 'Projects/' folder, and the first example project by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1524 +- Rename to {dataset-name}\_task_train/test by @Harold-lkk in https://github.com/open-mmlab/mmocr/pull/1541 +- Add print_config.py to the tools by @IncludeMathH in https://github.com/open-mmlab/mmocr/pull/1547 +- Add get_md5 by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1553 +- Add config generator by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1552 +- Support IC15_1811 by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1556 +- Update CT80 config by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1555 +- Add config generators to all textdet and textrecog configs by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1560 +- Refactor TPS by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/1240 +- Add TextSpottingConfigGenerator by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1561 +- Add common typing by @Harold-lkk in https://github.com/open-mmlab/mmocr/pull/1596 +- Update textrecog config and readme by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1597 +- Support head loss or postprocessor is None for only infer by @Harold-lkk in https://github.com/open-mmlab/mmocr/pull/1594 +- Textspotting datasample by @Harold-lkk in https://github.com/open-mmlab/mmocr/pull/1593 +- Simplify mono_gather by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1588 +- ABCNet v1 infer by @Harold-lkk in https://github.com/open-mmlab/mmocr/pull/1598 + +### Docs + +- Add Chinese Guidance on How to Add New Datasets to Dataset Preparer by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/1506 +- Update the qq group link by @vansin in https://github.com/open-mmlab/mmocr/pull/1569 +- Collapse some sections;

Preparing datasets is troublesome and tedious, especially in OCR domain where multiple datasets are usually required. In order to free our users from laborious work, we designed a [Dataset Preparer](https://mmocr.readthedocs.io/en/dev-1.x/user_guides/data_prepare/dataset_preparer.html) to help you get a bunch of datasets ready for use, with only **one line of command**! Dataset Preparer is also crafted to consist of a series of reusable modules, each responsible for handling one of the standardized phases throughout the preparation process, shortening the development cycle on supporting new datasets. + +### New Features & Enhancements + +- Add Dataset Preparer by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/1484 + +* support modified resnet structure used in oCLIP by @HannibalAPE in https://github.com/open-mmlab/mmocr/pull/1458 +* Add oCLIP configs by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1509 + +### Docs + +- Update install.md by @rogachevai in https://github.com/open-mmlab/mmocr/pull/1494 +- Refine some docs by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1455 +- Update some dataset preparer related docs by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/1502 +- oclip readme by @Harold-lkk in https://github.com/open-mmlab/mmocr/pull/1505 + +### Bug Fixes + +- Fix offline_eval error caused by new data flow by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/1500 + +### New Contributors + +- @rogachevai made their first contribution in https://github.com/open-mmlab/mmocr/pull/1494 +- @HannibalAPE made their first contribution in https://github.com/open-mmlab/mmocr/pull/1458 + +**Full Changelog**: https://github.com/open-mmlab/mmocr/compare/v1.0.0rc2...v1.0.0rc3 + +## v1.0.0rc2 (10/14/2022) + +This release relaxes the version requirement of `MMEngine` to `>=0.1.0, < 1.0.0`. + +## v1.0.0rc1 (10/09/2022) + +### Highlights + +This release fixes a severe bug leading to inaccurate metric report in multi-GPU training. +We release the weights for all the text recognition models in MMOCR 1.0 architecture.

MMOCR 1.x is based on [MMEngine](https://github.com/open-mmlab/mmengine), which provides a general and powerful runner that allows more flexible customizations and significantly simplifies the entrypoints of high-level interfaces. + +2. **Unified interfaces**. As a part of the OpenMMLab 2.0 projects, MMOCR 1.x unifies and refactors the interfaces and internal logics of train, testing, datasets, models, evaluation, and visualization. All the OpenMMLab 2.0 projects share the same design in those interfaces and logics to allow the emergence of multi-task/modality algorithms. + +3. **Cross project calling**. Benefiting from the unified design, you can use the models implemented in other OpenMMLab projects, such as MMDet. We provide an example of how to use MMDetection's Mask R-CNN through `MMDetWrapper`. Check our documents for more details. More wrappers will be released in the future. + +4. **Stronger visualization**. We provide a series of useful tools which are mostly based on brand-new visualizers. As a result, it is more convenient for the users to explore the models and datasets now. + +5. **More documentation and tutorials**. We add a bunch of documentation and tutorials to help users get started more smoothly. Read it [here](https://mmocr.readthedocs.io/en/dev-1.x/). + +### Breaking Changes + +We briefly list the major breaking changes here. +We will update the [migration guide](../migration.md) to provide complete details and migration instructions. + +#### Dependencies + +- MMOCR 1.x relies on MMEngine to run. MMEngine is a new foundational library for training deep learning models in OpenMMLab 2.0 models. The dependencies of file IO and training are migrated from MMCV 1.x to MMEngine. +- MMOCR 1.x relies on MMCV>=2.0.0rc0. Although MMCV no longer maintains the training functionalities since 2.0.0rc0, MMOCR 1.x relies on the data transforms, CUDA operators, and image processing interfaces in MMCV. Note that the package `mmcv` is the version that provide pre-built CUDA operators and `mmcv-lite` does not since MMCV 2.0.0rc0, while `mmcv-full` has been deprecated. + +#### Training and testing + +- MMOCR 1.x uses Runner in [MMEngine](https://github.com/open-mmlab/mmengine) rather than that in MMCV. The new Runner implements and unifies the building logic of dataset, model, evaluation, and visualizer. Therefore, MMOCR 1.x no longer maintains the building logics of those modules in `mmocr.train.apis` and `tools/train.py`. Those code have been migrated into [MMEngine](https://github.com/open-mmlab/mmengine/blob/main/mmengine/runner/runner.py). Please refer to the [migration guide of Runner in MMEngine](https://mmengine.readthedocs.io/en/latest/migration/runner.html) for more details. +- The Runner in MMEngine also supports testing and validation. The testing scripts are also simplified, which has similar logic as that in training scripts to build the runner. +- The execution points of hooks in the new Runner have been enriched to allow more flexible customization. Please refer to the [migration guide of Hook in MMEngine](https://mmengine.readthedocs.io/en/latest/migration/hook.html) for more details. +- Learning rate and momentum scheduling has been migrated from `Hook` to `Parameter Scheduler` in MMEngine. Please refer to the [migration guide of Parameter Scheduler in MMEngine](https://mmengine.readthedocs.io/en/latest/migration/param_scheduler.html) for more details. + +#### Configs + +- The [Runner in MMEngine](https://github.com/open-mmlab/mmengine/blob/main/mmengine/runner/runner.py) uses a different config structures to ease the understanding of the components in runner. Users can read the [config example of MMOCR](../user_guides/config.md) or refer to the [migration guide in MMEngine](https://mmengine.readthedocs.io/en/latest/migration/runner.html) for migration details. +- The file names of configs and models are also refactored to follow the new rules unified across OpenMMLab 2.0 projects. Please refer to the [user guides of config](../user_guides/config.md) for more details. + +#### Dataset + +The Dataset classes implemented in MMOCR 1.x all inherits from the `BaseDetDataset`, which inherits from the [BaseDataset in MMEngine](https://mmengine.readthedocs.io/en/latest/advanced_tutorials/basedataset.html). There are several changes of Dataset in MMOCR 1.x. + +- All the datasets support to serialize the data list to reduce the memory when multiple workers are built to accelerate data loading. +- The interfaces are changed accordingly. + +#### Data Transforms + +The data transforms in MMOCR 1.x all inherits from those in MMCV>=2.0.0rc0, which follows a new convention in OpenMMLab 2.0 projects. +The changes are listed as below: + +- The interfaces are also changed. Please refer to the [API Reference](https://mmocr.readthedocs.io/en/dev-1.x/) +- The functionality of some data transforms (e.g., `Resize`) are decomposed into several transforms. +- The same data transforms in different OpenMMLab 2.0 libraries have the same augmentation implementation and the logic of the same arguments, i.e., `Resize` in MMDet 3.x and MMOCR 1.x will resize the image in the exact same manner given the same arguments. + +#### Model + +The models in MMOCR 1.x all inherits from `BaseModel` in MMEngine, which defines a new convention of models in OpenMMLab 2.0 projects. Users can refer to the [tutorial of model](https://mmengine.readthedocs.io/en/latest/tutorials/model.html) in MMengine for more details. Accordingly, there are several changes as the following: + +- The model interfaces, including the input and output formats, are significantly simplified and unified following the new convention in MMOCR 1.x. Specifically, all the input data in training and testing are packed into `inputs` and `data_samples`, where `inputs` contains model inputs like a list of image tensors, and `data_samples` contains other information of the current data sample such as ground truths and model predictions. In this way, different tasks in MMOCR 1.x can share the same input arguments, which makes the models more general and suitable for multi-task learning. +- The model has a data preprocessor module, which is used to pre-process the input data of model. In MMOCR 1.x, the data preprocessor usually does necessary steps to form the input images into a batch, such as padding. It can also serve as a place for some special data augmentations or more efficient data transformations like normalization. +- The internal logic of model have been changed. In MMOCR 0.x, model used `forward_train` and `simple_test` to deal with different model forward logics. In MMOCR 1.x and OpenMMLab 2.0, the forward function has three modes: `loss`, `predict`, and `tensor` for training, inference, and tracing or other purposes, respectively. The forward function calls `self.loss()`, `self.predict()`, and `self._forward()` given the modes `loss`, `predict`, and `tensor`, respectively. + +#### Evaluation + +MMOCR 1.x mainly implements corresponding metrics for each task, which are manipulated by [Evaluator](https://mmengine.readthedocs.io/en/latest/design/evaluator.html) to complete the evaluation. +In addition, users can build evaluator in MMOCR 1.x to conduct offline evaluation, i.e., evaluate predictions that may not produced by MMOCR, prediction follows our dataset conventions. More details can be find in the [Evaluation Tutorial](https://mmengine.readthedocs.io/en/latest/tutorials/evaluation.html) in MMEngine. + +#### Visualization + +The functions of visualization in MMOCR 1.x are removed. Instead, in OpenMMLab 2.0 projects, we use [Visualizer](https://mmengine.readthedocs.io/en/latest/design/visualization.html) to visualize data. MMOCR 1.x implements `TextDetLocalVisualizer`, `TextRecogLocalVisualizer`, and `KIELocalVisualizer` to allow visualization of ground truths, model predictions, and feature maps, etc., at any place, for the three tasks supported in MMOCR. It also supports to dump the visualization data to any external visualization backends such as Tensorboard and Wandb. Check our [Visualization Document](https://mmocr.readthedocs.io/en/dev-1.x/user_guides/visualization.html) for more details. + +### Improvements + +- Most models enjoy a performance improvement from the new framework and refactor of data transforms. For example, in MMOCR 1.x, DBNet-R50 achieves **0.854** hmean score on ICDAR 2015, while the counterpart can only get **0.840** hmean score in MMOCR 0.x. +- Support mixed precision training of most of the models. However, the [rest models](https://mmocr.readthedocs.io/en/dev-1.x/user_guides/train_test.html#mixed-precision-training) are not supported yet because the operators they used might not be representable in fp16. We will update the documentation and list the results of mixed precision training. + +### Ongoing changes + +1. Test-time augmentation: which was supported in MMOCR 0.x, is not implemented yet in this version due to limited time slot. We will support it in the following releases with a new and simplified design. +2. Inference interfaces: a unified inference interfaces will be supported in the future to ease the use of released models. +3. Interfaces of useful tools that can be used in notebook: more useful tools that implemented in the `tools/` directory will have their python interfaces so that they can be used through notebook and in downstream libraries. +4. Documentation: we will add more design docs, tutorials, and migration guidance so that the community can deep dive into our new design, participate the future development, and smoothly migrate downstream libraries to MMOCR 1.x. diff --git a/pipeline/mmocr/docs/en/notes/changelog_v0.x.md b/pipeline/mmocr/docs/en/notes/changelog_v0.x.md new file mode 100644 index 0000000000000000000000000000000000000000..6b087b1d55cc73b5051fcd4272d97afa0bcbf753 --- /dev/null +++ b/pipeline/mmocr/docs/en/notes/changelog_v0.x.md @@ -0,0 +1,904 @@ +# Changelog + +## 0.6.0 (05/05/2022) + +### Highlights + +1. A new recognition algorithm [MASTER](https://arxiv.org/abs/1910.02562) has been added into MMOCR, which was the championship solution for the "ICDAR 2021 Competition on Scientific Table Image Recognition to Latex"! The model pre-trained on SynthText and MJSynth is available for testing! Credit to @JiaquanYe +2. [DBNet++](https://arxiv.org/abs/2202.10304) has been released now! A new Adaptive Scale Fusion module has been equipped for feature enhancement. Benefiting from this, the new model achieved 2% better h-mean score than its predecessor on the ICDAR2015 dataset. +3. Three more dataset converters are added: LSVT, RCTW and HierText. Check the dataset zoo ([Det](https://mmocr.readthedocs.io/en/latest/datasets/det.html#) & [Recog](https://mmocr.readthedocs.io/en/latest/datasets/recog.html) ) to explore further information. +4. To enhance the data storage efficiency, MMOCR now supports loading both images and labels from .lmdb format annotations for the text recognition task. To enable such a feature, the new lmdb_converter.py is ready for use to pack your cropped images and labels into an lmdb file. For a detailed tutorial, please refer to the following sections and the [doc](https://mmocr.readthedocs.io/en/latest/tools.html#convert-text-recognition-dataset-to-lmdb-format). +5. Testing models on multiple datasets is a widely used evaluation strategy. MMOCR now supports automatically reporting mean scores when there is more than one dataset to evaluate, which enables a more convenient comparison between checkpoints. [Doc](https://mmocr.readthedocs.io/en/latest/tutorials/dataset_types.html#getting-mean-evaluation-scores) +6. Evaluation is more flexible and customizable now. For text detection tasks, you can set the score threshold range where the best results might come out. ([Doc](https://mmocr.readthedocs.io/en/latest/tutorials/dataset_types.html#evaluation)) If too many results are flooding your text recognition train log, you can trim it by specifying a subset of metrics in evaluation config. Check out the [Evaluation](https://mmocr.readthedocs.io/en/latest/tutorials/dataset_types.html#ocrdataset) section for details. +7. MMOCR provides a script to convert the .json labels obtained by the popular annotation toolkit **Labelme** to MMOCR-supported data format. @Y-M-Y contributed a log analysis tool that helps users gain a better understanding of the entire training process. Read [tutorial docs](https://mmocr.readthedocs.io/en/latest/tools.html) to get started. + +### Lmdb Dataset + +Reading images or labels from files can be slow when data are excessive, e.g. on a scale of millions. Besides, in academia, most of the scene text recognition datasets are stored in lmdb format, including images and labels. To get closer to the mainstream practice and enhance the data storage efficiency, MMOCR now officially supports loading images and labels from lmdb datasets via a new pipeline [LoadImageFromLMDB](https://github.com/open-mmlab/mmocr/blob/878383b9de8d0e598f31fbb844ffcb0c305deb8b/mmocr/datasets/pipelines/loading.py#L140). +This section is intended to serve as a quick walkthrough for you to master this update and apply it to facilitate your research. + +#### Specifications + +To better align with the academic community, MMOCR now requires the following specifications for lmdb datasets: + +- The parameter describing the data volume of the dataset is `num-samples` instead of `total_number` (deprecated). +- Images and labels are stored with keys in the form of `image-000000001` and `label-000000001`, respectively. + +#### Usage + +1. Use existing academic lmdb datasets if they meet the specifications; or the tool provided by MMOCR to pack images & annotations into a lmdb dataset. + +- Previously, MMOCR had a function `txt2lmdb` (deprecated) that only supported converting labels to lmdb format. However, it is quite different from academic lmdb datasets, which usually contain both images and labels. Now MMOCR provides a new utility [lmdb_converter](https://github.com/open-mmlab/mmocr/blob/main/tools/data/utils/lmdb_converter.py) to convert recognition datasets with both images and labels to lmdb format. + +- Say that your recognition data in MMOCR's format are organized as follows. (See an example in [ocr_toy_dataset](https://github.com/open-mmlab/mmocr/tree/main/tests/data/ocr_toy_dataset)). + + ```text + # Directory structure + + โ”œโ”€โ”€img_path + | |โ€”โ€” img1.jpg + | |โ€”โ€” img2.jpg + | |โ€”โ€” ... + |โ€”โ€”label.txt (or label.jsonl) + + # Annotation format + + label.txt: img1.jpg HELLO + img2.jpg WORLD + ... + + label.jsonl: {'filename':'img1.jpg', 'text':'HELLO'} + {'filename':'img2.jpg', 'text':'WORLD'} + ... + ``` + +- Then pack these files up: + + ```bash + python tools/data/utils/lmdb_converter.py {PATH_TO_LABEL} {OUTPUT_PATH} --i {PATH_TO_IMAGES} + ``` + +- Check out [tools.md](https://github.com/open-mmlab/mmocr/blob/main/docs/en/tools.md) for more details. + +2. The second step is to modify the configuration files. For example, to train CRNN on MJ and ST datasets: + +- Set parser as `LineJsonParser` and `file_format` as 'lmdb' in [dataset config](https://github.com/open-mmlab/mmocr/blob/main/configs/_base_/recog_datasets/ST_MJ_train.py#L9) + + ```python + # configs/_base_/recog_datasets/ST_MJ_train.py + train1 = dict( + type='OCRDataset', + img_prefix=train_img_prefix1, + ann_file=train_ann_file1, + loader=dict( + type='AnnFileLoader', + repeat=1, + file_format='lmdb', + parser=dict( + type='LineJsonParser', + keys=['filename', 'text'], + )), + pipeline=None, + test_mode=False) + ``` + +- Use `LoadImageFromLMDB` in [pipeline](https://github.com/open-mmlab/mmocr/blob/main/configs/_base_/recog_pipelines/crnn_pipeline.py#L4): + + ```python + # configs/_base_/recog_pipelines/crnn_pipeline.py + train_pipeline = [ + dict(type='LoadImageFromLMDB', color_type='grayscale'), + ... + ``` + +3. You are good to go! Start training and MMOCR will load data from your lmdb dataset. + +### New Features & Enhancements + +- Add analyze_logs in tools and its description in docs by @Y-M-Y in https://github.com/open-mmlab/mmocr/pull/899 +- Add LSVT Data Converter by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/896 +- Add RCTW dataset converter by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/914 +- Support computing mean scores in UniformConcatDataset by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/981 +- Support loading images and labels from lmdb file by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/982 +- Add recog2lmdb and new toy dataset files by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/979 +- Add labelme converter for textdet and textrecog by @cuhk-hbsun in https://github.com/open-mmlab/mmocr/pull/972 +- Update CircleCI configs by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/918 +- Update Git Action by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/930 +- More customizable fields in dataloaders by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/933 +- Skip CIs when docs are modified by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/941 +- Rename Github tests, fix ignored paths by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/946 +- Support latest MMCV by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/959 +- Support dynamic threshold range in eval_hmean by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/962 +- Update the version requirement of mmdet in docker by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/966 +- Replace `opencv-python-headless` with `open-python` by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/970 +- Update Dataset Configs by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/980 +- Add SynthText dataset config by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/983 +- Automatically report mean scores when applicable by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/995 +- Add DBNet++ by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/973 +- Add MASTER by @JiaquanYe in https://github.com/open-mmlab/mmocr/pull/807 +- Allow choosing metrics to report in text recognition tasks by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/989 +- Add HierText converter by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/948 +- Fix lint_only in CircleCI by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/998 + +### Bug Fixes + +- Fix CircleCi Main Branch Accidentally Run PR Stage Test by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/927 +- Fix a deprecate warning about mmdet.datasets.pipelines.formating by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/944 +- Fix a Bug in ResNet plugin by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/967 +- revert a wrong setting in db_r18 cfg by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/978 +- Fix TotalText Anno version issue by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/945 +- Update installation step of `albumentations` by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/984 +- Fix ImgAug transform by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/949 +- Fix GPG key error in CI and docker by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/988 +- update label.lmdb by @Mountchicken in https://github.com/open-mmlab/mmocr/pull/991 +- correct meta key by @garvan2021 in https://github.com/open-mmlab/mmocr/pull/926 +- Use new image by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/976 +- Fix Data Converter Issues by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/955 + +### Docs + +- Update CONTRIBUTING.md by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/905 +- Fix the misleading description in test.py by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/908 +- Update recog.md for lmdb Generation by @xinke-wang in https://github.com/open-mmlab/mmocr/pull/934 +- Add MMCV by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/954 +- Add wechat QR code to CN readme by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/960 +- Update CONTRIBUTING.md by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/947 +- Use QR codes from MMCV by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/971 +- Renew dataset_types.md by @gaotongxiao in https://github.com/open-mmlab/mmocr/pull/997 + +### New Contributors + +- @Y-M-Y made their first contribution in https://github.com/open-mmlab/mmocr/pull/899 + +**Full Changelog**: https://github.com/open-mmlab/mmocr/compare/v0.5.0...v0.6.0 + +## 0.5.0 (31/03/2022) + +### Highlights + +1. MMOCR now supports SPACE recognition! (What a prominent feature!) Users only need to convert the recognition annotations that contain spaces from a plain `.txt` file to JSON line format `.jsonl`, and then revise a few configurations to enable the `LineJsonParser`. For more information, please read our step-by-step [tutorial](https://mmocr.readthedocs.io/en/latest/tutorials/blank_recog.html). +2. [Tesseract](https://github.com/tesseract-ocr/tesseract) is now available in MMOCR! While MMOCR is more flexible to support various downstream tasks, users might sometimes not be satisfied with DL models and would like to turn to effective legacy solutions. Therefore, we offer this option in `mmocr.utils.ocr` by wrapping Tesseract as a detector and/or recognizer. Users can easily create an MMOCR object by `MMOCR(det=โ€™Tesseractโ€™, recog=โ€™Tesseractโ€™)`. Credit to @garvan2021 +3. We release data converters for **16** widely used OCR datasets, including multiple scenarios such as document, handwritten, and scene text. Now it is more convenient to generate annotation files for these datasets. Check the dataset zoo ( [Det](https://mmocr.readthedocs.io/en/latest/datasets/det.html#) & [Recog](https://mmocr.readthedocs.io/en/latest/datasets/recog.html) ) to explore further information. +4. Special thanks to @EighteenSprings @BeyondYourself @yangrisheng, who had actively participated in documentation translation! + +### Migration Guide - ResNet + +Some refactoring processes are still going on. For text recognition models, we unified the [`ResNet-like` architectures](https://github.com/open-mmlab/mmocr/blob/72f945457324e700f0d14796dd10a51535c01a57/mmocr/models/textrecog/backbones/resnet.py) which are used as backbones. By introducing stage-wise and block-wise plugins, the refactored ResNet is highly flexible to support existing models, like ResNet31 and ResNet45, and other future designs of ResNet variants. + +#### Plugin + +- `Plugin` is a module category inherited from MMCV's implementation of `PLUGIN_LAYERS`, which can be inserted between each stage of ResNet or into a basicblock. You can find a simple implementation of plugin at [mmocr/models/textrecog/plugins/common.py](https://github.com/open-mmlab/mmocr/blob/72f945457324e700f0d14796dd10a51535c01a57/mmocr/models/textrecog/plugins/common.py), or click the button below. + +
+ Plugin Example + + ```python + @PLUGIN_LAYERS.register_module() + class Maxpool2d(nn.Module): + """A wrapper around nn.Maxpool2d(). + + Args: + kernel_size (int or tuple(int)): Kernel size for max pooling layer + stride (int or tuple(int)): Stride for max pooling layer + padding (int or tuple(int)): Padding for pooling layer + """ + + def __init__(self, kernel_size, stride, padding=0, **kwargs): + super(Maxpool2d, self).__init__() + self.model = nn.MaxPool2d(kernel_size, stride, padding) + + def forward(self, x): + """ + Args: + x (Tensor): Input feature map + + Returns: + Tensor: The tensor after Maxpooling layer. + """ + return self.model(x) + ``` + +
+ +#### Stage-wise Plugins + +- ResNet is composed of stages, and each stage is composed of blocks. E.g., ResNet18 is composed of 4 stages, and each stage is composed of basicblocks. For each stage, we provide two ports to insert stage-wise plugins by giving `plugins` parameters in ResNet. + + ```text + [port1: before stage] ---> [stage] ---> [port2: after stage] + ``` + +- E.g. Using a ResNet with four stages as example. Suppose we want to insert an additional convolution layer before each stage, and an additional convolution layer at stage 1, 2, 4. Then you can define the special ResNet18 like this + + ```python + resnet18_speical = ResNet( + # for simplicity, some required + # parameters are omitted + plugins=[ + dict( + cfg=dict( + type='ConvModule', + kernel_size=3, + stride=1, + padding=1, + norm_cfg=dict(type='BN'), + act_cfg=dict(type='ReLU')), + stages=(True, True, True, True), + position='before_stage') + dict( + cfg=dict( + type='ConvModule', + kernel_size=3, + stride=1, + padding=1, + norm_cfg=dict(type='BN'), + act_cfg=dict(type='ReLU')), + stages=(True, True, False, True), + position='after_stage') + ]) + ``` + +- You can also insert more than one plugin in each port and those plugins will be executed in order. Let's take ResNet in [MASTER](https://arxiv.org/abs/1910.02562) as an example: + +
+ Multiple Plugins Example + + - ResNet in Master is based on ResNet31. And after each stage, a module named `GCAModule` will be used. The `GCAModule` is inserted before the stage-wise convolution layer in ResNet31. In conlusion, there will be two plugins at `after_stage` port in the same time. + + ```python + resnet_master = ResNet( + # for simplicity, some required + # parameters are omitted + plugins=[ + dict( + cfg=dict(type='Maxpool2d', kernel_size=2, stride=(2, 2)), + stages=(True, True, False, False), + position='before_stage'), + dict( + cfg=dict(type='Maxpool2d', kernel_size=(2, 1), stride=(2, 1)), + stages=(False, False, True, False), + position='before_stage'), + dict( + cfg=dict(type='GCAModule', kernel_size=3, stride=1, padding=1), + stages=[True, True, True, True], + position='after_stage'), + dict( + cfg=dict( + type='ConvModule', + kernel_size=3, + stride=1, + padding=1, + norm_cfg=dict(type='BN'), + act_cfg=dict(type='ReLU')), + stages=(True, True, True, True), + position='after_stage') + ]) + + ``` + +
+ + - In each plugin, we will pass two parameters (`in_channels`, `out_channels`) to support operations that need the information of current channels. + +#### Block-wise Plugin (Experimental) + +- We also refactored the `BasicBlock` used in ResNet. Now it can be customized with block-wise plugins. Check [here](https://github.com/open-mmlab/mmocr/blob/72f945457324e700f0d14796dd10a51535c01a57/mmocr/models/textrecog/layers/conv_layer.py) for more details. + +- BasicBlock is composed of two convolution layer in the main branch and a shortcut branch. We provide four ports to insert plugins. + + ```text + [port1: before_conv1] ---> [conv1] ---> + [port2: after_conv1] ---> [conv2] ---> + [port3: after_conv2] ---> +(shortcut) ---> [port4: after_shortcut] + ``` + +- In each plugin, we will pass a parameter `in_channels` to support operations that need the information of current channels. + +- E.g. Build a ResNet with customized BasicBlock with an additional convolution layer before conv1: + +
+ Block-wise Plugin Example + + ```python + resnet_31 = ResNet( + in_channels=3, + stem_channels=[64, 128], + block_cfgs=dict(type='BasicBlock'), + arch_layers=[1, 2, 5, 3], + arch_channels=[256, 256, 512, 512], + strides=[1, 1, 1, 1], + plugins=[ + dict( + cfg=dict(type='Maxpool2d', + kernel_size=2, + stride=(2, 2)), + stages=(True, True, False, False), + position='before_stage'), + dict( + cfg=dict(type='Maxpool2d', + kernel_size=(2, 1), + stride=(2, 1)), + stages=(False, False, True, False), + position='before_stage'), + dict( + cfg=dict( + type='ConvModule', + kernel_size=3, + stride=1, + padding=1, + norm_cfg=dict(type='BN'), + act_cfg=dict(type='ReLU')), + stages=(True, True, True, True), + position='after_stage') + ]) + ``` + +
+ +#### Full Examples + +
+ResNet without plugins + +- ResNet45 is used in ASTER and ABINet without any plugins. + + ```python + resnet45_aster = ResNet( + in_channels=3, + stem_channels=[64, 128], + block_cfgs=dict(type='BasicBlock', use_conv1x1='True'), + arch_layers=[3, 4, 6, 6, 3], + arch_channels=[32, 64, 128, 256, 512], + strides=[(2, 2), (2, 2), (2, 1), (2, 1), (2, 1)]) + + resnet45_abi = ResNet( + in_channels=3, + stem_channels=32, + block_cfgs=dict(type='BasicBlock', use_conv1x1='True'), + arch_layers=[3, 4, 6, 6, 3], + arch_channels=[32, 64, 128, 256, 512], + strides=[2, 1, 2, 1, 1]) + ``` + +
+
+ResNet with plugins + +- ResNet31 is a typical architecture to use stage-wise plugins. Before the first three stages, Maxpooling layer is used. After each stage, a convolution layer with BN and ReLU is used. + + ```python + resnet_31 = ResNet( + in_channels=3, + stem_channels=[64, 128], + block_cfgs=dict(type='BasicBlock'), + arch_layers=[1, 2, 5, 3], + arch_channels=[256, 256, 512, 512], + strides=[1, 1, 1, 1], + plugins=[ + dict( + cfg=dict(type='Maxpool2d', + kernel_size=2, + stride=(2, 2)), + stages=(True, True, False, False), + position='before_stage'), + dict( + cfg=dict(type='Maxpool2d', + kernel_size=(2, 1), + stride=(2, 1)), + stages=(False, False, True, False), + position='before_stage'), + dict( + cfg=dict( + type='ConvModule', + kernel_size=3, + stride=1, + padding=1, + norm_cfg=dict(type='BN'), + act_cfg=dict(type='ReLU')), + stages=(True, True, True, True), + position='after_stage') + ]) + ``` + +
+ +### Migration Guide - Dataset Annotation Loader + +The annotation loaders, `LmdbLoader` and `HardDiskLoader`, are unified into `AnnFileLoader` for a more consistent design and wider support on different file formats and storage backends. `AnnFileLoader` can load the annotations from `disk`(default), `http` and `petrel` backend, and parse the annotation in `txt` or `lmdb` format. `LmdbLoader` and `HardDiskLoader` are deprecated, and users are recommended to modify their configs to use the new `AnnFileLoader`. Users can migrate their legacy loader `HardDiskLoader` referring to the following example: + +```python +# Legacy config +train = dict( + type='OCRDataset', + ... + loader=dict( + type='HardDiskLoader', + ...)) + +# Suggested config +train = dict( + type='OCRDataset', + ... + loader=dict( + type='AnnFileLoader', + file_storage_backend='disk', + file_format='txt', + ...)) +``` + +Similarly, using `AnnFileLoader` with `file_format='lmdb'` instead of `LmdbLoader` is strongly recommended. + +### New Features & Enhancements + +- Update mmcv install by @Harold-lkk in

We release a new text recognition model - [ABINet](https://arxiv.org/pdf/2103.06495.pdf) (CVPR 2021, Oral). With it dedicated model design and useful data augmentation transforms, ABINet can achieve the best performance on irregular text recognition tasks. [Check it out!](https://mmocr.readthedocs.io/en/latest/textrecog_models.html#read-like-humans-autonomous-bidirectional-and-iterative-language-modeling-for-scene-text-recognition) +2. We are also working hard to fulfill the requests from our community. + [OpenSet KIE](https://mmocr.readthedocs.io/en/latest/kie_models.html#wildreceiptopenset) is one of the achievement, which extends the application of SDMGR from text node classification to node-pair relation extraction. We also provide + a demo script to convert WildReceipt to open set domain, though it cannot + take the full advantage of OpenSet format. For more information, please read our + [tutorial](https://mmocr.readthedocs.io/en/latest/tutorials/kie_closeset_openset.html). +3. APIs of models can be exposed through TorchServe. [Docs](https://mmocr.readthedocs.io/en/latest/model_serving.html) + +### Breaking Changes & Migration Guide + +#### Postprocessor + +Some refactoring processes are still going on. For all text detection models, we unified their `decode` implementations into a new module category, `POSTPROCESSOR`, which is responsible for decoding different raw outputs into boundary instances. In all text detection configs, the `text_repr_type` argument in `bbox_head` is deprecated and will be removed in the future release. + +**Migration Guide**: Find a similar line from detection model's config: + +``` +text_repr_type=xxx, +``` + +And replace it with + +``` +postprocessor=dict(type='{MODEL_NAME}Postprocessor', text_repr_type=xxx)), +``` + +Take a snippet of PANet's config as an example. Before the change, its config for `bbox_head` looks like: + +``` + bbox_head=dict( + type='PANHead', + text_repr_type='poly', + in_channels=[128, 128, 128, 128], + out_channels=6, + module_loss=dict(type='PANModuleLoss')), +``` + +Afterwards: + +``` + bbox_head=dict( + type='PANHead', + in_channels=[128, 128, 128, 128], + out_channels=6, + module_loss=dict(type='PANModuleLoss'), + postprocessor=dict(type='PANPostprocessor', text_repr_type='poly')), +``` + +There are other postprocessors and each takes different arguments. Interested users can find their interfaces or implementations in `mmocr/models/textdet/postprocess` or through our [api docs](https://mmocr.readthedocs.io/en/latest/api.html#textdet-postprocess). + +#### New Config Structure + +We reorganized the `configs/` directory by extracting reusable sections into `configs/_base_`. Now the directory tree of `configs/_base_` is organized as follows: + +``` +_base_ +โ”œโ”€โ”€ det_datasets +โ”œโ”€โ”€ det_models +โ”œโ”€โ”€ det_pipelines +โ”œโ”€โ”€ recog_datasets +โ”œโ”€โ”€ recog_models +โ”œโ”€โ”€ recog_pipelines +โ””โ”€โ”€ schedules +``` + +Most of model configs are making full use of base configs now, which makes the overall structural clearer and facilitates fair +comparison across models. Despite the seemingly significant hierarchical difference, **these changes would not break the backward compatibility** as the names of model configs remain the same. + +### New Features + +- Support

https://github.com/open-mmlab/mmocr/compare/v0.3.0...0.4.0 + +## v0.3.0 (25/8/2021) + +### Highlights + +1. We add a new text recognition model -- SATRN! Its pretrained checkpoint achieves the best performance over other provided text recognition models. A lighter version of SATRN is also released which can obtain ~98% of the performance of the original model with only 45 MB in size. ([@2793145003](https://github.com/2793145003)) [#405](https://github.com/open-mmlab/mmocr/pull/405) +2. Improve the demo script, `ocr.py`, which supports applying end-to-end text detection, text recognition and key information extraction models on images with easy-to-use commands. Users can find its full documentation in the demo section. ([@samayala22](https://github.com/samayala22), [@manjrekarom](https://github.com/manjrekarom)) [#371](https://github.com/open-mmlab/mmocr/pull/371), [#386](https://github.com/open-mmlab/mmocr/pull/386), [#400](https://github.com/open-mmlab/mmocr/pull/400), [#374](https://github.com/open-mmlab/mmocr/pull/374), [#428](https://github.com/open-mmlab/mmocr/pull/428) +3. Our documentation is reorganized into a clearer structure. More useful contents are on the way! [#409](https://github.com/open-mmlab/mmocr/pull/409), [#454](https://github.com/open-mmlab/mmocr/pull/454) +4. The requirement of `Polygon3` is removed since this project is no longer maintained or distributed. We unified all its references to equivalent substitutions in `shapely` instead. [#448](https://github.com/open-mmlab/mmocr/pull/448) + +### Breaking Changes & Migration Guide + +1. Upgrade version requirement of MMDetection to 2.14.0 to avoid bugs [#382](https://github.com/open-mmlab/mmocr/pull/382) +2. MMOCR now has its own model and layer registries inherited from MMDetection's or MMCV's counterparts. ([#436](https://github.com/open-mmlab/mmocr/pull/436)) The modified hierarchical structure of the model registries are now organized as follows. + +```text +mmcv.MODELS -> mmdet.BACKBONES -> BACKBONES +mmcv.MODELS -> mmdet.NECKS -> NECKS +mmcv.MODELS -> mmdet.ROI_EXTRACTORS -> ROI_EXTRACTORS +mmcv.MODELS -> mmdet.HEADS -> HEADS +mmcv.MODELS -> mmdet.LOSSES -> LOSSES +mmcv.MODELS -> mmdet.DETECTORS -> DETECTORS +mmcv.ACTIVATION_LAYERS -> ACTIVATION_LAYERS +mmcv.UPSAMPLE_LAYERS -> UPSAMPLE_LAYERS +``` + +To migrate your old implementation to our new backend, you need to change the import path of any registries and their corresponding builder functions (including `build_detectors`) from `mmdet.models.builder` to `mmocr.models.builder`.

The design of its configuration file system integrates the ideas of modularity and inheritance to facilitate various experiments. + +## Common Usage + +```{note} +This section is recommended to be read together with the primary usage in {external+mmengine:doc}`MMEngine: Config `. +``` + +There are three most common operations in MMOCR: inheritance of configuration files, reference to `_base_` variables, and modification of `_base_` variables. Config provides two syntaxes for inheriting and modifying `_base_`, one for Python, Json, and Yaml, and one for Python configuration files only. In MMOCR, we **prefer the Python-only syntax**, so this will be the basis for further description. + +The `configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py` is used as an example to illustrate the three common uses. + +```Python +_base_ = [ + '_base_dbnet_resnet18_fpnc.py', + '../_base_/datasets/icdar2015.py', + '../_base_/default_runtime.py', + '../_base_/schedules/schedule_sgd_1200e.py', +] + +# dataset settings +icdar2015_textdet_train = _base_.icdar2015_textdet_train +icdar2015_textdet_train.pipeline = _base_.train_pipeline +icdar2015_textdet_test = _base_.icdar2015_textdet_test +icdar2015_textdet_test.pipeline = _base_.test_pipeline + +train_dataloader = dict( + batch_size=16, + num_workers=8, + persistent_workers=True, + sampler=dict(type='DefaultSampler', shuffle=True), + dataset=icdar2015_textdet_train) + +val_dataloader = dict( + batch_size=1, + num_workers=4, + persistent_workers=True, + sampler=dict(type='DefaultSampler', shuffle=False), + dataset=icdar2015_textdet_test) +``` + +### Configuration Inheritance + +There is an inheritance mechanism for configuration files, i.e. one configuration file A can use another configuration file B as its base and inherit all the fields directly from it, thus avoiding a lot of copy-pasting. + +In `dbnet_resnet18_fpnc_1200e_icdar2015.py` you can see that + +```Python +_base_ = [ + '_base_dbnet_resnet18_fpnc.py', + '../_base_/datasets/icdar2015.py', + '../_base_/default_runtime.py', + '../_base_/schedules/schedule_sgd_1200e.py', +] +``` + +The above statement reads all the base configuration files in the list, and all the fields in them are loaded into `dbnet_resnet18_fpnc_1200e_icdar2015.py`. We can see the structure of the configuration file after it has been parsed by running the following statement in a Python interpretation. + +```Python +from mmengine import Config +db_config = Config.fromfile('configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py') +print(db_config) +``` + +It can be found that the parsed configuration contains all the fields and information in the base configuration. + +```{note} +Variables with the same name cannot exist in each `_base_` profile. +``` + +### `_base_` Variable References + +Sometimes we may need to reference some fields in the `_base_` configuration directly in order to avoid duplicate definitions. Suppose we want to get the variable `pseudo` in the `_base_` configuration, we can get the variable in the `_base_` configuration directly via `_base_.pseudo`. + +This syntax has been used extensively in the configuration of MMOCR, and the dataset and pipeline configurations for each model in MMOCR are referenced in the *_base_* configuration. For example, + +```Python +icdar2015_textdet_train = _base_.icdar2015_textdet_train +# ... +train_dataloader = dict( + # ... + dataset=icdar2015_textdet_train) +``` + +
+ +### `_base_` Variable Modification + +In MMOCR, different algorithms usually have different pipelines in different datasets, so there are often scenarios to modify the `pipeline` in the dataset. There are also many scenarios where you need to modify variables in the `_base_` configuration, for example, modifying the training strategy of an algorithm, replacing some modules of an algorithm(backbone, etc.). Users can directly modify the referenced `_base_` variables using Python syntax. For dict, we also provide a method similar to class attribute modification to modify the contents of the dictionary directly. + +1. Dictionary + + Here is an example of modifying `pipeline` in a dataset. + + The dictionary can be modified using Python syntax: + + ```Python + # Get the dataset in _base_ + icdar2015_textdet_train = _base_.icdar2015_textdet_train + # You can modify the variables directly with Python's update + icdar2015_textdet_train.update(pipeline=_base_.train_pipeline) + ``` + + It can also be modified in the same way as changing Python class attributes. + + ```Python + # Get the dataset in _base_ + icdar2015_textdet_train = _base_.icdar2015_textdet_train + # The class property method is modified + icdar2015_textdet_train.pipeline = _base_.train_pipeline + ``` + +2. List + + Suppose the variable `pseudo = [1, 2, 3]` in the `_base_` configuration needs to be modified to `[1, 2, 4]`: + + ```Python + # pseudo.py + pseudo = [1, 2, 3] + ``` + + Can be rewritten directly as. + + ```Python + _base_ = ['pseudo.py'] + pseudo = [1, 2, 4] + ``` + + Or modify the list using Python syntax: + + ```Python + _base_ = ['pseudo.py'] + pseudo = _base_.pseudo + pseudo[2] = 4 + ``` + +### Command Line Modification + +Sometimes we only want to fix part of the configuration and do not want to modify the configuration file itself. For example, if you want to change the learning rate during an experiment but do not want to write a new configuration file, you can pass in parameters on the command line to override the relevant configuration. + +We can pass `--cfg-options` on the command line and modify the corresponding fields directly with the arguments after it. For example, we can run the following command to modify the learning rate temporarily for this training session. + +```Shell +python tools/train.py example.py --cfg-options optim_wrapper.optimizer.lr=1 +``` + +For more detailed usage, refer to {external+mmengine:doc}`MMEngine: Command Line Modification `. + +## Configuration Content + +With config files and Registry, MMOCR can modify the training parameters as well as the model configuration without invading the code. Specifically, users can customize the following modules in the configuration file: environment configuration, hook configuration, log configuration, training strategy configuration, data-related configuration, model-related configuration, evaluation configuration, and visualization configuration. + +This document will take the text detection algorithm `DBNet` and the text recognition algorithm `CRNN` as examples to introduce the contents of Config in detail. + +
+ +### Environment Configuration + +```Python +default_scope = 'mmocr' +env_cfg = dict( + cudnn_benchmark=True, + mp_cfg=dict(mp_start_method='fork', opencv_num_threads=0), + dist_cfg=dict(backend='nccl')) +randomness = dict(seed=None) +``` + +There are three main components: + +- Set the default `scope` of all registries to `mmocr`, ensuring that all modules are searched first from the `MMOCR` codebase. If the module does not exist, the search will continue from the upstream algorithm libraries `MMEngine` and `MMCV`, see {external+mmengine:doc}`MMEngine: Registry ` for more details. + +- `env_cfg` configures the distributed environment, see {external+mmengine:doc}`MMEngine: Runner ` for more details. + +- `randomness`: Some settings to make the experiment as reproducible + as possible like seed and deterministic. See {external+mmengine:doc}`MMEngine: Runner ` for more details. + +
+ +### Hook Configuration + +Hooks are divided into two main parts, default hooks, which are required for all tasks to run, and custom hooks, which generally serve specific algorithms or specific tasks (there are no custom hooks in MMOCR so far). + +```Python +default_hooks = dict( + timer=dict(type='IterTimerHook'), # Time recording, including data time as well as model inference time + logger=dict(type='LoggerHook', interval=1), # Collect logs from different components + param_scheduler=dict(type='ParamSchedulerHook'), # Update some hyper-parameters in optimizer + checkpoint=dict(type='CheckpointHook', interval=1),# Save checkpoint. `interval` control save interval + sampler_seed=dict(type='DistSamplerSeedHook'), # Data-loading sampler for distributed training. + sync_buffer=dict(type='SyncBuffersHook'), # Synchronize buffer in case of distributed training + visualization=dict( # Visualize the results of val and test + type='VisualizationHook', + interval=1, + enable=False, + show=False, + draw_gt=False, + draw_pred=False)) + custom_hooks = [] +``` + +Here is a brief description of a few hooks whose parameters may be changed frequently. For a general modification method, refer to Modify configuration. + +- `LoggerHook`: Used to configure the behavior of the logger. For example, by modifying `interval` you can control the interval of log printing, so that the log is printed once per `interval` iteration, for more settings refer to [LoggerHook API](mmengine.hooks.LoggerHook). + +- `CheckpointHook`: Used to configure checkpoint-related behavior, such as saving optimal and/or latest weights. You can also modify `interval` to control the checkpoint saving interval. More settings can be found in [CheckpointHook API](mmengine.hooks.CheckpointHook) + +- `VisualizationHook`: Used to configure visualization-related behavior, such as visualizing predicted results during validation or testing. **Default is off**. This Hook also depends on [Visualization Configuration](#Visualization-configuration). You can refer to [Visualizer](visualization.md) for more details. For more configuration, you can refer to [VisualizationHook API](mmocr.engine.hooks.VisualizationHook). + +If you want to learn more about the configuration of the default hooks and their functions, you can refer to {external+mmengine:doc}`MMEngine: Hooks `. + +
+ +### Log Configuration + +This section is mainly used to configure the log level and the log processor. + +```Python +log_level = 'INFO' # Logging Level +log_processor = dict(type='LogProcessor', + window_size=10, + by_epoch=True) +``` + +- The logging severity level is the same as that of {external+python:doc}`Python: logging ` + +- The log processor is mainly used to control the format of the output, detailed functions can be found in {external+mmengine:doc}`MMEngine: logging `. + + - `by_epoch=True` indicates that the logs are output in accordance to "epoch", and the log format needs to be consistent with the `type='EpochBasedTrainLoop'` parameter in `train_cfg`. For example, if you want to output logs by iteration number, you need to set ` by_epoch=False` in `log_processor` and `type='IterBasedTrainLoop'` in `train_cfg`. + + - `window_size` indicates the smoothing window of the loss, i.e. the average value of the various losses for the last `window_size` iterations. the final loss value printed in logger is the average of all the losses. + +
+ +### Training Strategy Configuration + +This section mainly contains optimizer settings, learning rate schedules and `Loop` settings. + +Training strategies usually vary for different tasks (text detection, text recognition, key information extraction). Here we explain the example configuration in `CRNN`, which is a text recognition model. + +```Python +# optimizer +optim_wrapper = dict( + type='OptimWrapper', optimizer=dict(type='Adadelta', lr=1.0)) +param_scheduler = [dict(type='ConstantLR', factor=1.0)] +train_cfg = dict(type='EpochBasedTrainLoop', + max_epochs=5, # train epochs + val_interval=1) # val interval +val_cfg = dict(type='ValLoop') +test_cfg = dict(type='TestLoop') +``` + +- `optim_wrapper` : It contains two main parts, OptimWrapper and Optimizer. Detailed usage information can be found in {external+mmengine:doc}`MMEngine: Optimizer Wrapper `. + + - The Optimizer wrapper supports different training strategies, including mixed-accuracy training (AMP), gradient accumulation, and gradient truncation. + + - All PyTorch optimizers are supported in the optimizer settings. All supported optimizers are available in {external+torch:ref}`PyTorch Optimizer List `. + +- `param_scheduler` : learning rate tuning strategy, supports most of the learning rate schedulers in PyTorch, such as `ExponentialLR`, `LinearLR`, `StepLR`, `MultiStepLR`, etc., and is used in much the same way, see [scheduler interface](mmengine.optim.scheduler), and more features can be found in the {external+mmengine:doc}`MMEngine: Optimizer Parameter Tuning Strategy `. + +- `train/test/val_cfg` : the execution flow of the task, MMEngine provides four kinds of flow: `EpochBasedTrainLoop`, `IterBasedTrainLoop`, `ValLoop`, `TestLoop` More can be found in {external+mmengine:doc}`MMEngine: loop controller `. + +### Data-related Configuration + +
+ +#### Dataset Configuration + +It is mainly about two parts. + +- The location of the dataset(s), including images and annotation files. + +- Data augmentation related configurations. In the OCR domain, data augmentation is usually strongly associated with the model. + +More parameter configurations can be found in [Data Base Class](#TODO). + +The naming convention for dataset fields in MMOCR is + +```Python +{dataset}_{task}_{train/val/test} = dict(...) +``` + +- dataset: See [dataset abbreviations](#TODO) + +- task: `det`(text detection), `rec`(text recognition), `kie`(key information extraction) + +- train/val/test: Dataset split. + +For example, for text recognition tasks, Syn90k is used as the training set, while icdar2013 and icdar2015 serve as the test sets. These are configured as follows. + +```Python +# text recognition dataset configuration +mjsynth_textrecog_train = dict( + type='OCRDataset', + data_root='data/rec/Syn90k/', + data_prefix=dict(img_path='mnt/ramdisk/max/90kDICT32px'), + ann_file='train_labels.json', + test_mode=False, + pipeline=None) + +icdar2013_textrecog_test = dict( + type='OCRDataset', + data_root='data/rec/icdar_2013/', + data_prefix=dict(img_path='Challenge2_Test_Task3_Images/'), + ann_file='test_labels.json', + test_mode=True, + pipeline=None) + +icdar2015_textrecog_test = dict( + type='OCRDataset', + data_root='data/rec/icdar_2015/', + data_prefix=dict(img_path='ch4_test_word_images_gt/'), + ann_file='test_labels.json', + test_mode=True, + pipeline=None) +``` + +
+ +#### Data Pipeline Configuration + +In MMOCR, dataset construction and data preparation are decoupled from each other. In other words, dataset classes such as `OCRDataset` are responsible for reading and parsing annotation files, while Data Transforms further implement data loading, data augmentation, data formatting and other related functions. + +In general, there are different augmentation strategies for training and testing, so there are usually `training_pipeline` and `testing_pipeline`. More information can be found in [Data Transforms](../basic_concepts/transforms.md) + +- The data augmentation process of the training pipeline is usually: data loading (LoadImageFromFile) -> annotation information loading (LoadXXXAnntation) -> data augmentation -> data formatting (PackXXXInputs). + +- The data augmentation flow of the test pipeline is usually: Data Loading (LoadImageFromFile) -> Data Augmentation -> Annotation Loading (LoadXXXAnntation) -> Data Formatting (PackXXXInputs). + +Due to the specificity of the OCR task, different models have different data augmentation techniques, and even the same model can have different data augmentation strategies for different datasets. Take `CRNN` as an example. + +```Python +# Data Augmentation +train_pipeline = [ + dict( + type='LoadImageFromFile', + color_type='grayscale', + ignore_empty=True, + min_size=5), + dict(type='LoadOCRAnnotations', with_text=True), + dict(type='Resize', scale=(100, 32), keep_ratio=False), + dict( + type='PackTextRecogInputs', + meta_keys=('img_path', 'ori_shape', 'img_shape', 'valid_ratio')) +] +test_pipeline = [ + dict( + type='LoadImageFromFile', + color_type='grayscale'), + dict( + type='RescaleToHeight', + height=32, + min_width=32, + max_width=None, + width_divisor=16), + dict(type='LoadOCRAnnotations', with_text=True), + dict( + type='PackTextRecogInputs', + meta_keys=('img_path', 'ori_shape', 'img_shape', 'valid_ratio')) +] +``` + +#### Dataloader Configuration + +The main configuration information needed to construct the dataset loader (dataloader), see {external+torch:doc}`PyTorch DataLoader ` for more tutorials. + +```Python +# Dataloader +train_dataloader = dict( + batch_size=64, + num_workers=8, + persistent_workers=True, + sampler=dict(type='DefaultSampler', shuffle=True), + dataset=dict( + type='ConcatDataset', + datasets=[mjsynth_textrecog_train], + pipeline=train_pipeline)) +val_dataloader = dict( + batch_size=1, + num_workers=4, + persistent_workers=True, + drop_last=False, + sampler=dict(type='DefaultSampler', shuffle=False), + dataset=dict( + type='ConcatDataset', + datasets=[icdar2013_textrecog_test, icdar2015_textrecog_test], + pipeline=test_pipeline)) +test_dataloader = val_dataloader +``` + +### Model-related Configuration + +

+ +#### Checkpoint Loading Configuration + +The model weights in the checkpoint file can be loaded via the `load_from` parameter, simply by setting the `load_from` parameter to the path of the checkpoint file. + +You can also resume training by setting `resume=True` to load the training status information in the checkpoint. When both `load_from` and `resume=True` are set, MMEngine will load the training state from the checkpoint file at the `load_from` path. + +If only `resume=True` is set, the executor will try to find and read the latest checkpoint file from the `work_dir` folder + +```Python +load_from = None # Path to load checkpoint +resume = False # whether resume +``` + +More can be found in {external+mmengine:doc}`MMEngine: Load Weights or Recover Training ` and [OCR Advanced Tips - Resume Training from Checkpoints](train_test.md#resume-training-from-a-checkpoint). + +

MMOCR performs this function by means of `Metric` and `Evaluator`. For more information, please refer to {external+mmengine:doc}`MMEngine: Evaluation ` and [Evaluation](../basic_concepts/evaluation.md) + +#### Evaluator + +Evaluator is mainly used to manage multiple datasets and multiple `Metrics`. For single and multiple dataset cases, there are single and multiple dataset evaluators, both of which can manage multiple `Metrics`. + +The single-dataset evaluator is configured as follows. + +```Python +# Single Dataset Single Metric +val_evaluator = dict( + type='Evaluator', + metrics=dict()) + +# Single Dataset Multiple Metric +val_evaluator = dict( + type='Evaluator', + metrics=[...]) +``` + +`MultiDatasetsEvaluator` differs from single-dataset evaluation in two aspects: `type` and `dataset_prefixes`. The evaluator type must be `MultiDatasetsEvaluator` and cannot be omitted. The `dataset_prefixes` is mainly used to distinguish the results of different datasets with the same evaluation metrics, see [MultiDatasetsEvaluation](../basic_concepts/evaluation.md). + +Assuming that we need to test accuracy on IC13 and IC15 datasets, the configuration is as follows. + +```Python +# Multiple datasets, single Metric +val_evaluator = dict( + type='MultiDatasetsEvaluator', + metrics=dict(), + dataset_prefixes=['IC13', 'IC15']) + +# Multiple datasets, multiple Metrics +val_evaluator = dict( + type='MultiDatasetsEvaluator', + metrics=[...], + dataset_prefixes=['IC13', 'IC15']) +``` + +#### Metric + +A metric evaluates a model's performance from a specific perspective. While there is no such common metric that fits all the tasks, MMOCR provides enough flexibility such that multiple metrics serving the same task can be used simultaneously. Here we list task-specific metrics for reference. + +Text detection: [`HmeanIOUMetric`](mmocr.evaluation.metrics.HmeanIOUMetric) + +Text recognition: [`WordMetric`](mmocr.evaluation.metrics.WordMetric), [`CharMetric`](mmocr.evaluation.metrics.CharMetric), [`OneMinusNEDMetric`](mmocr.evaluation.metrics.OneMinusNEDMetric) + +Key information extraction: [`F1Metric`](mmocr.evaluation.metrics.F1Metric) + +Text detection as an example, using a single `Metric` in the case of single dataset evaluation. + +```Python +val_evaluator = dict(type='HmeanIOUMetric') +``` + +Take text recognition as an example, multiple datasets (`IC13` and `IC15`) are evaluated using multiple `Metric`s (`WordMetric` and `CharMetric`). + +```Python +val_evaluator = dict( + type='MultiDatasetsEvaluator', + metrics=[ + dict( + type='WordMetric', + mode=['exact', 'ignore_case', 'ignore_case_symbol']), + dict(type='CharMetric') + ], + dataset_prefixes=['IC13', 'IC15']) +test_evaluator = val_evaluator +``` + +
+ +### Visualization Configuration + +Each task is bound to a task-specific visualizer. The visualizer is mainly used for visualizing or storing intermediate results of user models and visualizing val and test prediction results. The visualization results can also be stored in different backends such as WandB, TensorBoard, etc. through the corresponding visualization backend. Commonly used modification operations can be found in [visualization](visualization.md). + +The default configuration of visualization for text detection is as follows. + +```Python +vis_backends = [dict(type='LocalVisBackend')] +visualizer = dict( + type='TextDetLocalVisualizer', # Different visualizers for different tasks + vis_backends=vis_backends, + name='visualizer') +``` + +## Directory Structure + +All configuration files of `MMOCR` are placed under the `configs` folder. To avoid config files from being too long and improve their reusability and clarity, MMOCR takes advantage of the inheritance mechanism and split config files into eight sections. Since each section is closely related to the task type, MMOCR provides a task folder for each task in `configs/`, namely `textdet` (text detection task), `textrecog` (text recognition task), and `kie` (key information extraction). Each folder is further divided into two parts: `_base_` folder and algorithm configuration folders. + +1. the `_base_` folder stores some general config files unrelated to specific algorithms, and each section is divided into datasets, training strategies and runtime configurations by directory. + +2. The algorithm configuration folder stores config files that are strongly related to the algorithm. The algorithm configuration folder has two kinds of config files. + + 1. Config files starting with `_base_`: Configures the model and data pipeline of an algorithm. In OCR domain, data augmentation strategies are generally strongly related to the algorithm, so the model and data pipeline are usually placed in the same config file. + + 2. Other config files, i.e. the algorithm-specific configurations on the specific dataset(s): These are the full config files that further configure training and testing settings, aggregating `_base_` configurations that are scattered in different locations. Inside some modifications to the fields in `_base_` configs may be performed, such as data pipeline, training strategy, etc. + +All these config files are distributed in different folders according to their contents as follows: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

The file names are divided into four sections: algorithm information, module information, training information, and data information. Words that logically belong to different sections are connected by an underscore `'_'`, and multiple words in the same section are connected by a hyphen `'-'`. + +```Python +{{algorithm info}}_{{module info}}_{{training info}}_{{data info}}.py +``` + +- algorithm info: the name of the algorithm, such as dbnet, crnn, etc. + +- module info: list some intermediate modules in the order of data flow. Its content depends on the algorithm, and some modules strongly related to the model will be omitted to avoid an overly long name. For example: + + - For the text detection task and the key information extraction task : + + ```Python + {{algorithm info}}_{{backbone}}_{{neck}}_{{head}}_{{training info}}_{{data info}}.py + ``` + + `{head}` is usually omitted since it's algorithm-specific. + + - For text recognition tasks. + + ```Python + {{algorithm info}}_{{backbone}}_{{encoder}}_{{decoder}}_{{training info}}_{{data info}}.py + ``` + + Since encoder and decoder are generally bound to the algorithm, they are usually omitted. + +- training info: some settings of the training strategy, including batch size, schedule, etc. + +- data info: dataset name, modality, input size, etc., such as icdar2015 and synthtext. diff --git a/pipeline/mmocr/docs/en/user_guides/data_prepare/dataset_preparer.md b/pipeline/mmocr/docs/en/user_guides/data_prepare/dataset_preparer.md new file mode 100644 index 0000000000000000000000000000000000000000..55174cc5894e54db0daf9706ef406fce6f8d14c6 --- /dev/null +++ b/pipeline/mmocr/docs/en/user_guides/data_prepare/dataset_preparer.md @@ -0,0 +1,776 @@ +# Dataset Preparer (Beta) + +```{note} +Dataset Preparer is still in beta version and might not be stable enough.

Defaults to 4. | +| --task | str | Convert the dataset to the format of a specified task supported by MMOCR. options are: 'textdet', 'textrecog', 'textspotting', and 'kie'. | +| --splits | str | Splits of the dataset to be prepared. Multiple splits can be accepted. Defaults to `train val test`. | +| --lmdb | str | Store the data in LMDB format.

For example, the following command shows how to prepare the ICDAR2015 and TotalText datasets for text recognition task. + +```bash +python tools/dataset_converters/prepare_dataset.py icdar2015 totaltext --task textrecog --overwrite-cfg +``` + +To check the supported datasets of Dataset Preparer, please refer to [Dataset Zoo](./datasetzoo.md). Some of other datasets that need to be prepared manually are listed in [Text Detection](./det.md) and [Text Recognition](./recog.md). + +For users in China, more datasets can be downloaded from the opensource dataset platform: [OpenDataLab](https://opendatalab.com/). After downloading the data, you can place the files listed in `data_obtainer.save_name` in `data/cache` and rerun the script. + +## Advanced Usage + +### LMDB Format + +In text recognition tasks, we usually use LMDB format to store data to speed up data loading. When using the `prepare_dataset.py` script to prepare data, you can store data to the LMDB format by the `--lmdb` parameter. For example: + +```bash +python tools/dataset_converters/prepare_dataset.py icdar2015 --task textrecog --lmdb +``` + +As soon as the dataset is prepared, Dataset Preparer will generate `icdar2015_lmdb.py` in the `configs/textrecog/_base_/datasets/` directory. You can inherit this file and point the `dataloader` to the LMDB dataset. Moreover, the LMDB dataset needs to be loaded by [`LoadImageFromNDArray`](mmocr.datasets.transforms.LoadImageFromNDArray), thus you also need to modify `pipeline`. + +For example, if we want to change the training set of `configs/textrecog/crnn/crnn_mini-vgg_5e_mj.py` to icdar2015 generated before, we need to perform the following modifications: + +1. Modify `configs/textrecog/crnn/crnn_mini-vgg_5e_mj.py`: + + ```python + _base_ = [ + '../_base_/datasets/icdar2015_lmdb.py', # point to icdar2015 lmdb dataset + ... + ] + + train_list = [_base_.icdar2015_lmdb_textrecog_train] + ... + ``` + +2. Modify `train_pipeline` in `configs/textrecog/crnn/_base_crnn_mini-vgg.py`, change `LoadImageFromFile` to `LoadImageFromNDArray`: + + ```python + train_pipeline = [ + dict( + type='LoadImageFromNDArray', + color_type='grayscale', + file_client_args=file_client_args, + ignore_empty=True, + min_size=2), + ... + ] + ``` + +## Design + +There are many OCR datasets with different languages, annotation formats, and scenarios. There are generally two ways to use these datasets: to quickly understand the relevant information about the dataset, or to use it to train models. To meet these two usage scenarios, MMOCR provides dataset automatic preparation scripts. The dataset automatic preparation script uses modular design, which greatly enhances scalability, and allows users to easily configure other public or private datasets. The configuration files for the dataset automatic preparation script are uniformly stored in the `dataset_zoo/` directory. Users can find all the configuration files for the dataset preparation scripts officially supported by MMOCR in this directory. The directory structure of this folder is as follows: + +```text +dataset_zoo/ +โ”œโ”€โ”€ icdar2015 +โ”‚ โ”œโ”€โ”€ metafile.yml +โ”‚ โ”œโ”€โ”€ sample_anno.md +โ”‚ โ”œโ”€โ”€ textdet.py +โ”‚ โ”œโ”€โ”€ textrecog.py +โ”‚ โ””โ”€โ”€ textspotting.py +โ””โ”€โ”€ wildreceipt + โ”œโ”€โ”€ metafile.yml + โ”œโ”€โ”€ sample_anno.md + โ”œโ”€โ”€ kie.py + โ”œโ”€โ”€ textdet.py + โ”œโ”€โ”€ textrecog.py + โ””โ”€โ”€ textspotting.py +``` + +### Dataset-related Information + +The relevant information of a dataset includes the annotation format, annotation examples, and basic statistical information of the dataset. Although this information can be found on the official website of each dataset, it is scattered across various websites, and users need to spend a lot of time to discover the basic information of the dataset. Therefore, MMOCR has designed some paradigms to help users quickly understand the basic information of the dataset. MMOCR divides the relevant information of the dataset into two parts. One part is the basic information of the dataset, including the year of publication, the authors of the paper, and copyright information, etc. The other part is the annotation information of the dataset, including the annotation format and annotation examples. MMOCR provides a paradigm for each part, and contributors can fill in the basic information of the dataset according to the paradigm. This way, users can quickly understand the basic information of the dataset. Based on the basic information of the dataset, MMOCR provides a `metafile.yml` file, which contains the basic information of the corresponding dataset, including the year of publication, the authors of the paper, and copyright information, etc. In this way, users can quickly understand the basic information of the dataset. This file is not mandatory during the dataset preparation process (so users can ignore it when adding their own private datasets), but to better understand the information of various public datasets, MMOCR recommends that users read the corresponding metafile information before using the dataset preparation script to understand whether the characteristics of the dataset meet the user's needs. MMOCR uses ICDAR2015 as an example, and its sample content is shown below: + +```yaml +Name: 'Incidental Scene Text IC15' +Paper: + Title: ICDAR 2015 Competition on Robust Reading + URL: https://rrc.cvc.uab.es/files/short_rrc_2015.pdf + Venue: ICDAR + Year: '2015' + BibTeX: '@inproceedings{karatzas2015icdar, + title={ICDAR 2015 competition on robust reading}, + author={Karatzas, Dimosthenis and Gomez-Bigorda, Lluis and Nicolaou, Anguelos and Ghosh, Suman and Bagdanov, Andrew and Iwamura, Masakazu and Matas, Jiri and Neumann, Lukas and Chandrasekhar, Vijay Ramaseshan and Lu, Shijian and others}, + booktitle={2015 13th international conference on document analysis and recognition (ICDAR)}, + pages={1156--1160}, + year={2015}, + organization={IEEE}}' +Data: + Website: https://rrc.cvc.uab.es/?ch=4 + Language: + - English + Scene: + - Natural Scene + Granularity: + - Word + Tasks: + - textdet + - textrecog + - textspotting + License: + Type: CC BY 4.0 + Link: https://creativecommons.org/licenses/by/4.0/ +``` + +Specifically, MMOCR lists the meaning of each field in the following table: + +| Field Name | Meaning | +| :--------------- | :------------------------------------------------------------------------------------------------------- | +| Name | The name of the dataset | +| Paper.Title | The title of the paper for the dataset | +| Paper.URL | The URL of the paper for the dataset | +| Paper.Venue | The venue of the paper for the dataset | +| Paper.Year | The year of publication for the paper | +| Paper.BibTeX | The BibTeX citation of the paper for the dataset | +| Data.Website | The official website of the dataset | +| Data.Language | The supported languages of the dataset | +| Data.Scene | The supported scenes of the dataset, such as `Natural Scene`, `Document`, `Handwritten`, etc. | +| Data.Granularity | The supported granularities of the dataset, such as `Character`, `Word`, `Line`, etc. | +| Data.Tasks | The supported tasks of the dataset, such as `textdet`, `textrecog`, `textspotting`, `kie`, etc. | +| Data.License | License information for the dataset.

MMOCR uses ICDAR2015 as an example, and the sample content is as follows: + +````markdown + **Text Detection** + + ```text + # x1,y1,x2,y2,x3,y3,x4,y4,trans + + 377,117,463,117,465,130,378,130,Genaxis Theatre + 493,115,519,115,519,131,493,131,[06] + 374,155,409,155,409,170,374,170,### +```` + +`sample_anno.md` provides annotation information for different tasks of the dataset, including the format of the annotation files (text corresponds to `txt` files, and the format of the annotation files can also be found in `meta.yml`), and examples of the annotations. + +With the information in these two files, users can quickly understand the basic information of the dataset. Additionally, MMOCR has summarized the basic information of all datasets, and users can view the basic information of all datasets in the [Overview](.overview.md). + +### Dataset Usage + +After decades of development, the OCR field has seen a series of related datasets emerge, often providing text annotation files in various styles, making it necessary for users to perform format conversion when using these datasets. Therefore, to facilitate dataset preparation for users, we have designed the Dataset Preparer to help users quickly prepare datasets in the format supported by MMOCR. For details, please refer to the [Dataset Format](../../basic_concepts/datasets.md) document. The following figure shows a typical workflow for running the Dataset Preparer. + +![workflow](https://user-images.githubusercontent.com/87774050/233025618-aa3c3ad6-c595-49a3-b080-a6284748c0c1.jpg) + +The figure shows that when running the Dataset Preparer, the following operations will be performed in sequence: + +1. For the training set, validation set, and test set, the preparers will perform: + 1. [Dataset download, extraction, and movement (Obtainer)](#Dataset-download-extraction-and-movement-obtainer) + 2. [Matching annotations with images (Gatherer)](#dataset-collection-gatherer) + 3. [Parsing original annotations (Parser)](#dataset-parsing-parser) + 4. [Packing annotations into a unified format (Packer)](#dataset-conversion-packer) + 5. [Saving annotations (Dumper)](#annotation-saving-dumper) +2. Delete files (Delete) +3. Generate the configuration file for the data set (Config Generator). + +To handle various types of datasets, MMOCR has designed each component as a plug-and-play module, and allows users to configure the dataset preparation process through configuration files located in `dataset_zoo/`. These configuration files are in Python format and can be used in the same way as other configuration files in MMOCR, as described in the [Configuration File documentation](../config.md). + +In `dataset_zoo/`, each dataset has its own folder, and the configuration files are named after the task to distinguish different configurations under different tasks. Taking the text detection part of ICDAR2015 as an example, the sample configuration file `dataset_zoo/icdar2015/textdet.py` is shown below: + +```python +data_root = 'data/icdar2015' +cache_path = 'data/cache' +train_preparer = dict( + obtainer=dict( + type='NaiveDataObtainer', + cache_path=cache_path, + files=[ + dict( + url='https://rrc.cvc.uab.es/downloads/ch4_training_images.zip', + save_name='ic15_textdet_train_img.zip', + md5='c51cbace155dcc4d98c8dd19d378f30d', + content=['image'], + mapping=[['ic15_textdet_train_img', 'textdet_imgs/train']]), + dict( + url='https://rrc.cvc.uab.es/downloads/' + 'ch4_training_localization_transcription_gt.zip', + save_name='ic15_textdet_train_gt.zip', + md5='3bfaf1988960909014f7987d2343060b', + content=['annotation'], + mapping=[['ic15_textdet_train_gt', 'annotations/train']]), + ]), + gatherer=dict( + type='PairGatherer', + img_suffixes=['.jpg', '.JPG'], + rule=[r'img_(\d+)\.([jJ][pP][gG])', r'gt_img_\1.txt']), + parser=dict(type='ICDARTxtTextDetAnnParser', encoding='utf-8-sig'), + packer=dict(type='TextDetPacker'), + dumper=dict(type='JsonDumper'), +) + +test_preparer = dict( + obtainer=dict( + type='NaiveDataObtainer', + cache_path=cache_path, + files=[ + dict( + url='https://rrc.cvc.uab.es/downloads/ch4_test_images.zip', + save_name='ic15_textdet_test_img.zip', + md5='97e4c1ddcf074ffcc75feff2b63c35dd', + content=['image'], + mapping=[['ic15_textdet_test_img', 'textdet_imgs/test']]), + dict( + url='https://rrc.cvc.uab.es/downloads/' + 'Challenge4_Test_Task4_GT.zip', + save_name='ic15_textdet_test_gt.zip', + md5='8bce173b06d164b98c357b0eb96ef430', + content=['annotation'], + mapping=[['ic15_textdet_test_gt', 'annotations/test']]), + ]), + gatherer=dict( + type='PairGatherer', + img_suffixes=['.jpg', '.JPG'], + rule=[r'img_(\d+)\.([jJ][pP][gG])', r'gt_img_\1.txt']), + parser=dict(type='ICDARTxtTextDetAnnParser', encoding='utf-8-sig'), + packer=dict(type='TextDetPacker'), + dumper=dict(type='JsonDumper'), +) + +delete = ['annotations', 'ic15_textdet_test_img', 'ic15_textdet_train_img'] +config_generator = dict(type='TextDetConfigGenerator') +``` + +#### Dataset download extraction and movement (Obtainer) + +The `obtainer` module in Dataset Preparer is responsible for downloading, extracting, and moving the dataset. Currently, MMOCR only provides the `NaiveDataObtainer`. Generally speaking, the built-in `NaiveDataObtainer` is sufficient for downloading most datasets that can be accessed through direct links, and supports operations such as extraction, moving files, and renaming. However, MMOCR currently does not support automatically downloading datasets stored in resources that require login, such as Baidu or Google Drive. Here is a brief introduction to the `NaiveDataObtainer`. + +| Field Name | Meaning | +| ---------- | -------------------------------------------------------------------------------------------- | +| cache_path | Dataset cache path, used to store the compressed files downloaded during dataset preparation | +| data_root | Root directory where the dataset is stored | +| files | Dataset file list, used to describe the download information of the dataset | + +The `files` field is a list, and each element in the list is a dictionary used to describe the download information of a dataset file. The table below shows the meaning of each field: + +| Field Name | Meaning | +| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------ | +| url | Download link for the dataset file | +| save_name | Name used to save the dataset file | +| md5 (optional) | MD5 hash of the dataset file, used to check if the downloaded file is complete | +| split (optional) | Dataset split the file belongs to, such as `train`, `test`, etc., this field can be omitted | +| content (optional) | Content of the dataset file, such as `image`, `annotation`, etc., this field can be omitted | +| mapping (optional) | Decompression mapping of the dataset file, used to specify the storage location of the file after decompression, this field can be omitted | + +The Dataset Preparer follows the following conventions: + +- Images of different types of datasets are moved to the corresponding category `{taskname}_imgs/{split}/` folder, such as `textdet_imgs/train/`. +- For a annotation file containing annotation information for all images, the annotations are moved to `annotations/{split}.*` file, such as `annotations/train.json`. +- For a annotation file containing annotation information for one image, all annotation files are moved to `annotations/{split}/` folder, such as `annotations/train/`. +- For some other special cases, such as all training, testing, and validation images are in one folder, the images can be moved to a self-set folder, such as `{taskname}_imgs/imgs/`, and the image storage location should be specified in the subsequent `gatherer` module. + +An example configuration is as follows: + +```python + obtainer=dict( + type='NaiveDataObtainer', + cache_path=cache_path, + files=[ + dict( + url='https://rrc.cvc.uab.es/downloads/ch4_training_images.zip', + save_name='ic15_textdet_train_img.zip', + md5='c51cbace155dcc4d98c8dd19d378f30d', + content=['image'], + mapping=[['ic15_textdet_train_img', 'textdet_imgs/train']]), + dict( + url='https://rrc.cvc.uab.es/downloads/' + 'ch4_training_localization_transcription_gt.zip', + save_name='ic15_textdet_train_gt.zip', + md5='3bfaf1988960909014f7987d2343060b', + content=['annotation'], + mapping=[['ic15_textdet_train_gt', 'annotations/train']]), + ]), +``` + +#### Dataset collection (Gatherer) + +The `gatherer` module traverses the files in the dataset directory, matches image files with their corresponding annotation files, and organizes a file list for the `parser` module to read. Therefore, it is necessary to know the matching rules between image files and annotation files in the current dataset. There are two commonly used annotation storage formats for OCR datasets: one is multiple annotation files corresponding to multiple images, and the other is a single annotation file corresponding to multiple images, for example: + +```text +Many-to-Many +โ”œโ”€โ”€ {taskname}_imgs/{split}/img_img_1.jpg +โ”œโ”€โ”€ annotations/{split}/gt_img_1.txt +โ”œโ”€โ”€ {taskname}_imgs/{split}/img_2.jpg +โ”œโ”€โ”€ annotations/{split}/gt_img_2.txt +โ”œโ”€โ”€ {taskname}_imgs/{split}/img_3.JPG +โ”œโ”€โ”€ annotations/{split}/gt_img_3.txt + +One-to-Many +โ”œโ”€โ”€ {taskname}/{split}/img_1.jpg +โ”œโ”€โ”€ {taskname}/{split}/img_2.jpg +โ”œโ”€โ”€ {taskname}/{split}/img_3.JPG +โ”œโ”€โ”€ annotations/gt.txt +``` + +Specific design is as follows: + +![Gatherer](https://user-images.githubusercontent.com/24622904/224935300-9f27e471-e87d-42db-a11d-adc8f603a7c9.png) + +MMOCR has built-in `PairGatherer` and `MonoGatherer` to handle the two common cases mentioned above. `PairGatherer` is used for many-to-many situations, while `MonoGatherer` is used for one-to-many situations. + +```{note} +To simplify processing, the gatherer assumes that the dataset's images and annotations are stored separately in `{taskname}_imgs/{split}/` and `annotations/`, respectively. In particular, for many-to-many situations, the annotation file needs to be placed in `annotations/{split}`. +``` + +- In the many-to-many case, `PairGatherer` needs to find the image files and corresponding annotation files according to a certain naming convention. First, the suffix of the image needs to be specified by the `img_suffixes` parameter, as in the example above `img_suffixes=[.jpg,.JPG]`. In addition, a pair of [regular expressions](https://docs.python.org/3/library/re.html) `rule` is used to specify the correspondence between the image and annotation files. For example, `rule=[r'img_(\d+)\.([jJ][pP][gG])'๏ผŒr'gt_img_\1.txt']`. The first regular expression is used to match the image file name, `\d+` is used to match the image sequence number, and `([jJ][pP][gG])` is used to match the image suffix. The second regular expression is used to match the annotation file name, where `\1` associates the matched image sequence number with the annotation file sequence number. An example configuration is: + +```python + gatherer=dict( + type='PairGatherer', + img_suffixes=['.jpg', '.JPG'], + rule=[r'img_(\d+)\.([jJ][pP][gG])', r'gt_img_\1.txt']), +``` + +For the case of one-to-many, it is usually simple, and the user only needs to specify the annotation file name. For example, for the training set configuration: + +```python + gatherer=dict(type='MonoGatherer', ann_name='train.txt'), +``` + +MMOCR has also made conventions on the return value of `Gatherer`. `Gatherer` returns a tuple with two elements. The first element is a list of image paths (including all image paths) or the folder containing all images. The second element is a list of annotation file paths (including all annotation file paths) or the path of the annotation file (the annotation file contains all image annotation information). Specifically, the return value of `PairGatherer` is (list of image paths, list of annotation file paths), as shown below: + +```python + (['{taskname}_imgs/{split}/img_1.jpg', '{taskname}_imgs/{split}/img_2.jpg', '{taskname}_imgs/{split}/img_3.JPG'], + ['annotations/{split}/gt_img_1.txt', 'annotations/{split}/gt_img_2.txt', 'annotations/{split}/gt_img_3.txt']) +``` + +`MonoGatherer` returns a tuple containing the path to the image directory and the path to the annotation file, as follows: + +```python + ('{taskname}/{split}', 'annotations/gt.txt') +``` + +#### Dataset parsing (Parser) + +`Parser` is mainly used to parse the original annotation files. Since the original annotation formats vary greatly, MMOCR provides `BaseParser` as a base class, which users can inherit to implement their own `Parser`. In `BaseParser`, MMOCR has designed two interfaces: `parse_files` and `parse_file`, where the annotation parsing is conventionally carried out. For the two different input situations of `Gatherer` (many-to-many, one-to-many), the implementations of these two interfaces should be different. + +- `BaseParser` by default handles the many-to-many situation. Among them, `parse_files` distributes the data in parallel to multiple `parse_file` processes, and each `parse_file` parses the annotation of a single image separately. +- For the one-to-many situation, the user needs to override `parse_files` to implement loading the annotation and returning standardized results. + +The interface of `BaseParser` is defined as follows: + +```python +class BaseParser: + def __call__(self, img_paths, ann_paths): + return self.parse_files(img_paths, ann_paths) + + def parse_files(self, img_paths: Union[List[str], str], + ann_paths: Union[List[str], str]) -> List[Tuple]: + samples = track_parallel_progress_multi_args( + self.parse_file, (img_paths, ann_paths), nproc=self.nproc) + return samples + + @abstractmethod + def parse_file(self, img_path: str, ann_path: str) -> Tuple: + + raise NotImplementedError +``` + +In order to ensure the uniformity of subsequent modules, MMOCR has made conventions for the return values of `parse_files` and `parse_file`. The return value of `parse_file` is a tuple, the first element of which is the image path, and the second element is the annotation information. The annotation information is a list, each element of which is a dictionary with the fields `poly`, `text`, and `ignore`, as shown below: + +```python +# An example of returned values: +( + 'imgs/train/xxx.jpg', + [ + dict( + poly=[0, 1, 1, 1, 1, 0, 0, 0], + text='hello', + ignore=False), + ... + ] +) +``` + +The output of `parse_files` is a list, and each element in the list is the return value of `parse_file`. An example is: + +```python +[ + ( + 'imgs/train/xxx.jpg', + [ + dict( + poly=[0, 1, 1, 1, 1, 0, 0, 0], + text='hello', + ignore=False), + ... + ] + ), + ... +] +``` + +#### Dataset Conversion (Packer) + +`Packer` is mainly used to convert data into a unified annotation format, because the input data is the output of parsers and the format has been fixed. Therefore, the packer only needs to convert the input format into a unified annotation format for each task. Currently, MMOCR supports tasks such as text detection, text recognition, end-to-end OCR, and key information extraction, and MMOCR has a corresponding packer for each task, as shown below: + +![Packer](https://user-images.githubusercontent.com/24622904/225248832-11be894f-7b44-4ffa-83e1-8478c37b5e63.png) + +For text detection, end-to-end OCR, and key information extraction, MMOCR has a unique corresponding `Packer`. However, for text recognition, MMOCR provides two `Packer` options: `TextRecogPacker` and `TextRecogCropPacker`, due to the existence of two types of datasets: + +- Each image is a recognition sample, and the annotation information returned by the `parser` is only a `dict(text='xxx')`. In this case, `TextRecogPacker` can be used. +- The dataset does not crop text from the image, and it essentially contains end-to-end OCR annotations that include the position information of the text and the corresponding text information. `TextRecogCropPacker` will crop the text from the image and then convert it into the unified format for text recognition. + +#### Annotation Saving (Dumper) + +The `dumper` module is used to determine what format the data should be saved in. Currently, MMOCR supports `JsonDumper`, `WildreceiptOpensetDumper`, and `TextRecogLMDBDumper`. They are used to save data in the standard MMOCR JSON format, the Wildreceipt format, and the LMDB format commonly used in the academic community for text recognition, respectively. + +#### Delete files (Delete) + +When processing a dataset, temporary files that are not needed may be generated. Here, a list of such files or folders can be passed in, which will be deleted when the conversion is finished. + +#### Generate the configuration file for the dataset (ConfigGenerator) + +In order to automatically generate basic configuration files after preparing the dataset, MMOCR has implemented `TextDetConfigGenerator`, `TextRecogConfigGenerator`, and `TextSpottingConfigGenerator` for each task. The main parameters supported by these generators are as follows: + +| Field Name | Meaning | +| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| data_root | Root directory where the dataset is stored. | +| train_anns | Path to the training set annotations in the configuration file. If not specified, it defaults to `[dict(ann_file='{taskname}_train.json', dataset_postfix='']`. | +| val_anns | Path to the validation set annotations in the configuration file. If not specified, it defaults to an empty string. | +| test_anns | Path to the test set annotations in the configuration file. If not specified, it defaults to `[dict(ann_file='{taskname}_test.json', dataset_postfix='']`. | +| config_path | Path to the directory where the configuration files for the algorithm are stored. The configuration generator will write the default configuration to `{config_path}/{taskname}/_base_/datasets/{dataset_name}.py`. If not specified, it defaults to `configs/`. | + +After preparing all the files for the dataset, the configuration generator will automatically generate the basic configuration files required to call the dataset. Below is a minimal example of a `TextDetConfigGenerator` configuration: + +```python +config_generator = dict(type='TextDetConfigGenerator') +``` + +The generated file will be placed by default under `configs/{task}/_base_/datasets/`. In this example, the basic configuration file for the ICDAR 2015 dataset will be generated at `configs/textdet/_base_/datasets/icdar2015.py`. + +```python +icdar2015_textdet_data_root = 'data/icdar2015' + +icdar2015_textdet_train = dict( + type='OCRDataset', + data_root=icdar2015_textdet_data_root, + ann_file='textdet_train.json', + filter_cfg=dict(filter_empty_gt=True, min_size=32), + pipeline=None) + +icdar2015_textdet_test = dict( + type='OCRDataset', + data_root=icdar2015_textdet_data_root, + ann_file='textdet_test.json', + test_mode=True, + pipeline=None) +``` + +If the dataset is special and there are several variants of the annotations, the configuration generator also supports generating variables pointing to each variant in the base configuration. However, this requires users to differentiate them by using different `dataset_postfix` when setting up. For example, the ICDAR 2015 text recognition dataset has two annotation versions for the test set, the original version and the 1811 version, which can be specified in `test_anns` as follows: + +```python +config_generator = dict( + type='TextRecogConfigGenerator', + test_anns=[ + dict(ann_file='textrecog_test.json'), + dict(dataset_postfix='857', ann_file='textrecog_test_857.json') + ]) +``` + +The configuration generator will generate the following configurations: + +```python +icdar2015_textrecog_data_root = 'data/icdar2015' + +icdar2015_textrecog_train = dict( + type='OCRDataset', + data_root=icdar2015_textrecog_data_root, + ann_file='textrecog_train.json', + pipeline=None) + +icdar2015_textrecog_test = dict( + type='OCRDataset', + data_root=icdar2015_textrecog_data_root, + ann_file='textrecog_test.json', + test_mode=True, + pipeline=None) + +icdar2015_1811_textrecog_test = dict( + type='OCRDataset', + data_root=icdar2015_textrecog_data_root, + ann_file='textrecog_test_1811.json', + test_mode=True, + pipeline=None) +``` + +With this file, MMOCR can directly import this dataset into the `dataloader` from the model configuration file (the following sample is excerpted from [`configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py`](/configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py)): + +```python +_base_ = [ + '../_base_/datasets/icdar2015.py', + # ... +] + +# dataset settings +icdar2015_textdet_train = _base_.icdar2015_textdet_train +icdar2015_textdet_test = _base_.icdar2015_textdet_test +# ... + +train_dataloader = dict( + dataset=icdar2015_textdet_train) + +val_dataloader = dict( + dataset=icdar2015_textdet_test) + +test_dataloader = val_dataloader +``` + +```{note} +By default, the configuration generator does not overwrite existing base configuration files unless the user manually specifies `overwrite-cfg` when running the script. +``` + +## Adding a new dataset to Dataset Preparer + +### Adding Public Datasets + +MMOCR has already supported many [commonly used public datasets](./datasetzoo.md). If the dataset you want to use has not been supported yet and you are willing to [contribute to the MMOCR](../../notes/contribution_guide.md) open-source community, you can follow the steps below to add a new dataset. + +In the following example, we will show you how to add the **ICDAR2013** dataset step by step. + +#### Adding `metafile.yml` + +First, make sure that the dataset you want to add does not already exist in `dataset_zoo/`. Then, create a new folder named after the dataset you want to add, such as `icdar2013/` (usually, use lowercase alphanumeric characters without symbols to name the dataset). In the `icdar2013/` folder, create a `metafile.yml` file and fill in the basic information of the dataset according to the following template: + +```yaml +Name: 'Incidental Scene Text IC13' +Paper: + Title: ICDAR 2013 Robust Reading Competition + URL: https://www.imlab.jp/publication_data/1352/icdar_competition_report.pdf + Venue: ICDAR + Year: '2013' + BibTeX: '@inproceedings{karatzas2013icdar, + title={ICDAR 2013 robust reading competition}, + author={Karatzas, Dimosthenis and Shafait, Faisal and Uchida, Seiichi and Iwamura, Masakazu and i Bigorda, Lluis Gomez and Mestre, Sergi Robles and Mas, Joan and Mota, David Fernandez and Almazan, Jon Almazan and De Las Heras, Lluis Pere}, + booktitle={2013 12th international conference on document analysis and recognition}, + pages={1484--1493}, + year={2013}, + organization={IEEE}}' +Data: + Website: https://rrc.cvc.uab.es/?ch=2 + Language: + - English + Scene: + - Natural Scene + Granularity: + - Word + Tasks: + - textdet + - textrecog + - textspotting + License: + Type: N/A + Link: N/A + Format: .txt + Keywords: + - Horizontal +``` + +#### Add Annotation Examples + +Finally, you can add an annotation example file `sample_anno.md` under the `dataset_zoo/icdar2013/` directory to help the documentation script add annotation examples when generating documentation. The annotation example file is a Markdown file that typically contains the raw data format of a single sample. For example, the following code block shows a sample data file for the ICDAR2013 dataset: + +````markdown + **Text Detection** + + ```text + # train split + # x1 y1 x2 y2 "transcript" + + 158 128 411 181 "Footpath" + 443 128 501 169 "To" + 64 200 363 243 "Colchester" + + # test split + # x1, y1, x2, y2, "transcript" + + 38, 43, 920, 215, "Tiredness" + 275, 264, 665, 450, "kills" + 0, 699, 77, 830, "A" +```` + +#### Add configuration files for corresponding tasks + +In the `dataset_zoo/icdar2013` directory, add a `.py` configuration file named after the task. For example, `textdet.py`, `textrecog.py`, `textspotting.py`, `kie.py`, etc. The configuration template is shown below: + +```python +data_root = '' +data_cache = 'data/cache' +train_prepare = dict( + obtainer=dict( + type='NaiveObtainer', + data_cache=data_cache, + files=[ + dict( + url='xx', + md5='', + save_name='xxx', + mapping=list()) + ]), + gatherer=dict(type='xxxGatherer', **kwargs), + parser=dict(type='xxxParser', **kwargs), + packer=dict(type='TextxxxPacker'), # Packer for the task + dumper=dict(type='JsonDumper'), +) +test_prepare = dict( + obtainer=dict( + type='NaiveObtainer', + data_cache=data_cache, + files=[ + dict( + url='xx', + md5='', + save_name='xxx', + mapping=list()) + ]), + gatherer=dict(type='xxxGatherer', **kwargs), + parser=dict(type='xxxParser', **kwargs), + packer=dict(type='TextxxxPacker'), # Packer for the task + dumper=dict(type='JsonDumper'), +) +``` + +Taking the file detection task as an example, let's introduce the specific content of the configuration file. In general, users do not need to implement new `obtainer`, `gatherer`, `packer`, or `dumper`, but usually need to implement a new `parser` according to the annotation format of the dataset. + +Regarding the configuration of `obtainer`, we will not go into detail here, and you can refer to [Data set download, extraction, and movement (Obtainer)](#Dataset-download-extraction-and-movement-obtainer). + +For the `gatherer`, by observing the obtained ICDAR2013 dataset files, we found that each image has a corresponding `.txt` format annotation file: + +```text +data_root +โ”œโ”€โ”€ textdet_imgs/train/ +โ”‚ โ”œโ”€โ”€ img_1.jpg +โ”‚ โ”œโ”€โ”€ img_2.jpg +โ”‚ โ””โ”€โ”€ ... +โ”œโ”€โ”€ annotations/train/ +โ”‚ โ”œโ”€โ”€ gt_img_1.txt +โ”‚ โ”œโ”€โ”€ gt_img_2.txt +โ”‚ โ””โ”€โ”€ ... +``` + +Moreover, the name of each annotation file corresponds to the image: `gt_img_1.txt` corresponds to `img_1.jpg`, and so on. Therefore, `PairGatherer` can be used to match them. + +```python +gatherer=dict( + type='PairGatherer', + img_suffixes=['.jpg'], + rule=[r'(\w+)\.jpg', r'gt_\1.txt']) +``` + +The first regular expression in the rule is used to match the image file name, and the second regular expression is used to match the annotation file name. Here, `(\w+)` is used to match the image file name, and `gt_\1.txt` is used to match the annotation file name, where `\1` represents the content matched by the first regular expression. That is, it replaces `img_xx.jpg` with `gt_img_xx.txt`. + +Next, you need to implement a `parser` to parse the original annotation files into a standard format. Usually, before adding a new dataset, users can browse the [details page](./datasetzoo.md) of the supported datasets and check if there is a dataset with the same format. If there is, you can use the parser of that dataset directly. Otherwise, you need to implement a new format parser. + +Data format parsers are stored in the `mmocr/datasets/preparers/parsers` directory. All parsers need to inherit from `BaseParser` and implement the `parse_file` or `parse_files` method. For more information, please refer to [Parsing original annotations (Parser)](#dataset-parsing-parser). + +By observing the annotation files of the ICDAR2013 dataset: + +```text +158 128 411 181 "Footpath" +443 128 501 169 "To" +64 200 363 243 "Colchester" +542, 710, 938, 841, "break" +87, 884, 457, 1021, "could" +517, 919, 831, 1024, "save" +``` + +We found that the built-in `ICDARTxtTextDetAnnParser` already meets the requirements, so we can directly use this parser and configure it in the `preparer`. + +```python +parser=dict( + type='ICDARTxtTextDetAnnParser', + remove_strs=[',', '"'], + encoding='utf-8', + format='x1 y1 x2 y2 trans', + separator=' ', + mode='xyxy') +``` + +In the configuration for the `ICDARTxtTextDetAnnParser`, `remove_strs=[',', '"']` is specified to remove extra quotes and commas in the annotation files. In the `format` section, `x1 y1 x2 y2 trans` indicates that each line in the annotation file contains four coordinates and a text content separated by spaces (`separator`=' '). Also, `mode` is set to `xyxy`, which means that the coordinates in the annotation file are the coordinates of the top-left and bottom-right corners, so that `ICDARTxtTextDetAnnParser` can parse the annotations into a unified format. + +For the `packer`, taking the file detection task as an example, its `packer` is `TextDetPacker`, and its configuration is as follows: + +```python +packer=dict(type='TextDetPacker') +``` + +Finally, specify the `dumper`, which is generally saved in json format. Its configuration is as follows: + +```python +dumper=dict(type='JsonDumper') +``` + +After the above configuration, the configuration file for the ICDAR2013 training set is as follows: + +```python +train_preparer = dict( + obtainer=dict( + type='NaiveDataObtainer', + cache_path=cache_path, + files=[ + dict( + url='https://rrc.cvc.uab.es/downloads/' + 'Challenge2_Training_Task12_Images.zip', + save_name='ic13_textdet_train_img.zip', + md5='a443b9649fda4229c9bc52751bad08fb', + content=['image'], + mapping=[['ic13_textdet_train_img', 'textdet_imgs/train']]), + dict( + url='https://rrc.cvc.uab.es/downloads/' + 'Challenge2_Training_Task1_GT.zip', + save_name='ic13_textdet_train_gt.zip', + md5='f3a425284a66cd67f455d389c972cce4', + content=['annotation'], + mapping=[['ic13_textdet_train_gt', 'annotations/train']]), + ]), + gatherer=dict( + type='PairGatherer', + img_suffixes=['.jpg'], + rule=[r'(\w+)\.jpg', r'gt_\1.txt']), + parser=dict( + type='ICDARTxtTextDetAnnParser', + remove_strs=[',', '"'], + format='x1 y1 x2 y2 trans', + separator=' ', + mode='xyxy'), + packer=dict(type='TextDetPacker'), + dumper=dict(type='JsonDumper'), +) +``` + +To automatically generate the basic configuration after the dataset is prepared, you also need to configure the corresponding task's `config_generator`. + +In this example, since it is a text detection task, you only need to set the generator to `TextDetConfigGenerator`. + +```python +config_generator = dict(type='TextDetConfigGenerator') +``` + +### Use DataPreparer to prepare customized dataset + +\[Coming Soon\] diff --git a/pipeline/mmocr/docs/en/user_guides/data_prepare/det.md b/pipeline/mmocr/docs/en/user_guides/data_prepare/det.md new file mode 100644 index 0000000000000000000000000000000000000000..8221215000d13e747495f09aaa11398f1aa1d774 --- /dev/null +++ b/pipeline/mmocr/docs/en/user_guides/data_prepare/det.md @@ -0,0 +1,635 @@ +# Text Detection + +```{note} +This page is a manual preparation guide for datasets not yet supported by [Dataset Preparer](./dataset_preparer.md), which all these scripts will be eventually migrated into. +``` + +## Overview + +| Dataset | Images | | Annotation Files | | | +| :---------------: | :------------------------------------------------------: | :------------------------------------------------: | :-----------------------------------------------------------------: | :-----: | :-: | +| | | training | validation | testing | | +| ICDAR2011 | [homepage](https://rrc.cvc.uab.es/?ch=1) | -

The default OpenCV +backend used in MMCV would read them and apply the rotation on the images. However, their gold annotations are made on the raw pixels, and such +inconsistency results in false examples in the training set. Therefore, users should use `dict(type='LoadImageFromFile', color_type='color_ignore_orientation')` in pipelines to change MMCV's default loading behaviour.

For example, you can store data to `TensorBoard` and `Wandb` by simply inserting the following code block into the configuration file. + +```Python +_base_.visualizer.vis_backends = [ + dict(type='LocalVisBackend'), + dict(type='TensorboardVisBackend'), + dict(type='WandbVisBackend'),] +``` + +## Plot + +### Plot the prediction results + +MMOCR mainly uses [`VisualizationHook`](mmocr.engine.hooks.VisualizationHook) to plot the prediction results of validation and test, by default `VisualizationHook` is off, and the default configuration is as follows. + +```Python +visualization=dict( # user visualization of validation and test results + type='VisualizationHook', + enable=False, + interval=1, + show=False, + draw_gt=False, + draw_pred=False) +``` + +The following table shows the parameters supported by `VisualizationHook`. + +| Parameters | Description | +| :--------: | :-----------------------------------------------------------------------------------------------------------: | +| enable | The VisualizationHook is turned on and off by the enable parameter, which is the default state. | +| interval | Controls how much iteration to store or display the results of a val or test if VisualizationHook is enabled. | +| show | Controls whether to visualize the results of val or test. | +| draw_gt | Whether the results of val or test are drawn with or without labeling information | +| draw_pred | whether to draw predictions for val or test results | + +If you want to enable `VisualizationHook` related functions and configurations during training or testing, you only need to modify the configuration, take `dbnet_resnet18_fpnc_1200e_icdar2015.py` as an example, draw annotations and predictions at the same time, and display the images, the configuration can be modified as follows + +```Python +visualization = _base_.default_hooks.visualization +visualization.update( + dict(enable=True, show=True, draw_gt=True, draw_pred=True)) +``` + +
+ +
+ +If you only want to see the predicted result information you can just let `draw_pred=True` + +```Python +visualization = _base_.default_hooks.visualization +visualization.update( + dict(enable=True, show=True, draw_gt=False, draw_pred=True)) +``` + +
+ +
+ +The `test.py` procedure is further simplified by providing the `--show` and `--show-dir` parameters to visualize the annotation and prediction results during the test without modifying the configuration. + +```Shell +# Show test results +python tools/test.py configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py dbnet_r18_fpnc_1200e_icdar2015/epoch_400.pth --show + +# Specify where to store the prediction results +python tools/test.py configs/textdet/dbnet/dbnet_resnet18_fpnc_1200e_icdar2015.py dbnet_r18_fpnc_1200e_icdar2015/epoch_400.pth --show-dir imgs/ +``` + +

Deprecation of file_client_args in favor of backend_args +4. Added a new MMOCR tutorial notebook + +To know more about the updates in MMOCR 1.0, please refer to [What's New in MMOCR 1.x](https://mmocr.readthedocs.io/en/dev-1.x/migration/news.html), or +Read [Changelog](https://mmocr.readthedocs.io/en/dev-1.x/notes/changelog.html) for more details! + +## Introduction + +MMOCR is an open-source toolbox based on PyTorch and mmdetection for text detection, text recognition, and the corresponding downstream tasks including key information extraction. It is part of the [OpenMMLab](https://openmmlab.com/) project. + +The main branch works with **PyTorch 1.6+**. + +
+ +
+ +### Major Features + +- **Comprehensive Pipeline** + + The toolbox supports not only text detection and text recognition, but also their downstream tasks such as key information extraction. + +- **Multiple Models** + + The toolbox supports a wide variety of state-of-the-art models for text detection, text recognition and key information extraction. + +- **Modular Design** + + The modular design of MMOCR enables users to define their own optimizers, data preprocessors, and model components such as backbones, necks and heads as well as losses. Please refer to [Overview](https://mmocr.readthedocs.io/en/dev-1.x/get_started/overview.html) for how to construct a customized model. + +- **Numerous Utilities** + + The toolbox provides a comprehensive set of utilities which can help users assess the performance of models. It includes visualizers which allow visualization of images, ground truths as well as predicted bounding boxes, and a validation tool for evaluating checkpoints during training. It also includes data converters to demonstrate how to convert your own data to the annotation files which the toolbox supports. + +## Installation + +MMOCR depends on [PyTorch](https://pytorch.org/), [MMEngine](https://github.com/open-mmlab/mmengine), [MMCV](https://github.com/open-mmlab/mmcv) and [MMDetection](https://github.com/open-mmlab/mmdetection). +Below are quick steps for installation. +Please refer to [Install Guide](https://mmocr.readthedocs.io/en/dev-1.x/get_started/install.html) for more detailed instruction. + +```shell +conda create -n open-mmlab python=3.8 pytorch=1.10 cudatoolkit=11.3 torchvision -c pytorch -y +conda activate open-mmlab +pip3 install openmim +git clone https://github.com/open-mmlab/mmocr.git +cd mmocr +mim install -e . +``` + +## Get Started + +Please see [Quick Run](https://mmocr.readthedocs.io/en/dev-1.x/get_started/quick_run.html) for the basic usage of MMOCR. + +## [Model Zoo](https://mmocr.readthedocs.io/en/dev-1.x/modelzoo.html) + +Supported algorithms: + +

[Language Matters: A Weakly Supervised Vision-Language Pre-training Approach for Scene Text Detection and Spotting](https://www.ecva.net/papers/eccv_2022/papers_ECCV/papers/136880282.pdf) + + + +## Abstract + +Recently, Vision-Language Pre-training (VLP) techniques have greatly benefited various vision-language tasks by jointly learning visual and textual representations, which intuitively helps in Optical Character Recognition (OCR) tasks due to the rich visual and textual information in scene text images. However, these methods cannot well cope with OCR tasks because of the difficulty in both instance-level text encoding and image-text pair acquisition (i.e. images and captured texts in them). This paper presents a weakly supervised pre-training method, oCLIP, which can acquire effective scene text representations by jointly learning and aligning visual and textual information. Our network consists of an image encoder and a character-aware text encoder that extract visual and textual features, respectively, as well as a visual-textual decoder that models the interaction among textual and visual features for learning effective scene text representations. With the learning of textual features, the pre-trained model can attend texts in images well with character awareness. Besides, these designs enable the learning from weakly annotated texts (i.e. partial texts in images without text bounding boxes) which mitigates the data annotation constraint greatly. Experiments over the weakly annotated images in ICDAR2019-LSVT show that our pre-trained model improves F-score by +2.5% and +4.8% while transferring its weights to other text detection and spotting networks, respectively. In addition, the proposed method outperforms existing pre-training techniques consistently across multiple public datasets (e.g., +3.2% and +1.3% for Total-Text and CTW1500). + +

Conventional template matching based approaches fail to generalize well to document images of unseen templates, and are not robust against text recognition errors. In this paper, we propose an end-to-end Spatial Dual-Modality Graph Reasoning method (SDMG-R) to extract key information from unstructured document images. We model document images as dual-modality graphs, nodes of which encode both the visual and textual features of detected text regions, and edges of which represent the spatial relations between neighboring text regions. The key information extraction is solved by iteratively propagating messages along graph edges and reasoning the categories of graph nodes. In order to roundly evaluate our proposed method as well as boost the future research, we release a new dataset named WildReceipt, which is collected and annotated tailored for the evaluation of key information extraction from document images of unseen templates in the wild. It contains 25 key information categories, a total of about 69000 text boxes, and is about 2 times larger than the existing public datasets. Extensive experiments validate that all information including visual features, textual features and spatial relations can benefit key information extraction. It has been shown that SDMG-R can effectively extract key information from document images of unseen templates, and obtain new state-of-the-art results on the recent popular benchmark SROIE and our WildReceipt. Our code and dataset will be publicly released. + +

[Real-time Scene Text Detection with Differentiable Binarization](https://arxiv.org/abs/1911.08947) + + + +## Abstract + +Recently, segmentation-based methods are quite popular in scene text detection, as the segmentation results can more accurately describe scene text of various shapes such as curve text. However, the post-processing of binarization is essential for segmentation-based detection, which converts probability maps produced by a segmentation method into bounding boxes/regions of text. In this paper, we propose a module named Differentiable Binarization (DB), which can perform the binarization process in a segmentation network. Optimized along with a DB module, a segmentation network can adaptively set the thresholds for binarization, which not only simplifies the post-processing but also enhances the performance of text detection. Based on a simple segmentation network, we validate the performance improvements of DB on five benchmark datasets, which consistently achieves state-of-the-art results, in terms of both detection accuracy and speed. In particular, with a light-weight backbone, the performance improvements by DB are significant so that we can look for an ideal tradeoff between detection accuracy and efficiency. Specifically, with a backbone of ResNet-18, our detector achieves an F-measure of 82.8, running at 62 FPS, on the MSRA-TD500 dataset. + +

[Real-Time Scene Text Detection with Differentiable Binarization and Adaptive Scale Fusion](https://arxiv.org/abs/2202.10304) + + + +## Abstract + +Recently, segmentation-based scene text detection methods have drawn extensive attention in the scene text detection field, because of their superiority in detecting the text instances of arbitrary shapes and extreme aspect ratios, profiting from the pixel-level descriptions. However, the vast majority of the existing segmentation-based approaches are limited to their complex post-processing algorithms and the scale robustness of their segmentation models, where the post-processing algorithms are not only isolated to the model optimization but also time-consuming and the scale robustness is usually strengthened by fusing multi-scale feature maps directly. In this paper, we propose a Differentiable Binarization (DB) module that integrates the binarization process, one of the most important steps in the post-processing procedure, into a segmentation network. Optimized along with the proposed DB module, the segmentation network can produce more accurate results, which enhances the accuracy of text detection with a simple pipeline. Furthermore, an efficient Adaptive Scale Fusion (ASF) module is proposed to improve the scale robustness by fusing features of different scales adaptively. By incorporating the proposed DB and ASF with the segmentation network, our proposed scene text detector consistently achieves state-of-the-art results, in terms of both detection accuracy and speed, on five standard benchmarks. + +

relational reasoning graph network for arbitrary shape text detection](https://arxiv.org/abs/2003.07493) + + + +## Abstract + +Arbitrary shape text detection is a challenging task due to the high variety and complexity of scenes texts. In this paper, we propose a novel unified relational reasoning graph network for arbitrary shape text detection. In our method, an innovative local graph bridges a text proposal model via Convolutional Neural Network (CNN) and a deep relational reasoning network via Graph Convolutional Network (GCN), making our network end-to-end trainable. To be concrete, every text instance will be divided into a series of small rectangular components, and the geometry attributes (e.g., height, width, and orientation) of the small components will be estimated by our text proposal model. Given the geometry attributes, the local graph construction model can roughly establish linkages between different text components. For further reasoning and deducing the likelihood of linkages between the component and its neighbors, we adopt a graph-based network to perform deep relational reasoning on local graphs.

Most of existing methods model text instances in image spatial domain via masks or contour point sequences in the Cartesian or the polar coordinate system. However, the mask representation might lead to expensive post-processing, while the point sequence one may have limited capability to model texts with highly-curved shapes. To tackle these problems, we model text instances in the Fourier domain and propose one novel Fourier Contour Embedding (FCE) method to represent arbitrary shaped text contours as compact signatures. We further construct FCENet with a backbone, feature pyramid networks (FPN) and a simple post-processing with the Inverse Fourier Transformation (IFT) and Non-Maximum Suppression (NMS). Different from previous methods, FCENet first predicts compact Fourier signatures of text instances, and then reconstructs text contours via IFT and NMS during test. Extensive experiments demonstrate that FCE is accurate and robust to fit contours of scene texts even with highly-curved shapes, and also validate the effectiveness and the good generalization of FCENet for arbitrary-shaped text detection. Furthermore, experimental results show that our FCENet is superior to the state-of-the-art (SOTA) methods on CTW1500 and Total-Text, especially on challenging highly-curved text subset. + +

[Mask R-CNN](https://arxiv.org/abs/1703.06870) + + + +## Abstract + +We present a conceptually simple, flexible, and general framework for object instance segmentation. Our approach efficiently detects objects in an image while simultaneously generating a high-quality segmentation mask for each instance. The method, called Mask R-CNN, extends Faster R-CNN by adding a branch for predicting an object mask in parallel with the existing branch for bounding box recognition. Mask R-CNN is simple to train and adds only a small overhead to Faster R-CNN, running at 5 fps. Moreover, Mask R-CNN is easy to generalize to other tasks, e.g., allowing us to estimate human poses in the same framework. We show top results in all three tracks of the COCO suite of challenges, including instance segmentation, bounding-box object detection, and person keypoint detection. Without bells and whistles, Mask R-CNN outperforms all existing, single-model entries on every task, including the COCO 2016 challenge winners. We hope our simple and effective approach will serve as a solid baseline and help ease future research in instance-level recognition. + +

[Efficient and Accurate Arbitrary-Shaped Text Detection with Pixel Aggregation Network](https://arxiv.org/abs/1908.05900) + + + +## Abstract + +Scene text detection, an important step of scene text reading systems, has witnessed rapid development with convolutional neural networks. Nonetheless, two main challenges still exist and hamper its deployment to real-world applications. The first problem is the trade-off between speed and accuracy. The second one is to model the arbitrary-shaped text instance. Recently, some methods have been proposed to tackle arbitrary-shaped text detection, but they rarely take the speed of the entire pipeline into consideration, which may fall short in practical this http URL this paper, we propose an efficient and accurate arbitrary-shaped text detector, termed Pixel Aggregation Network (PAN), which is equipped with a low computational-cost segmentation head and a learnable post-processing. More specifically, the segmentation head is made up of Feature Pyramid Enhancement Module (FPEM) and Feature Fusion Module (FFM). FPEM is a cascadable U-shaped module, which can introduce multi-level information to guide the better segmentation. FFM can gather the features given by the FPEMs of different depths into a final feature for segmentation. The learnable post-processing is implemented by Pixel Aggregation (PA), which can precisely aggregate text pixels by predicted similarity vectors. Experiments on several standard benchmarks validate the superiority of the proposed PAN. It is worth noting that our method can achieve a competitive F-measure of 79.9% at 84.2 FPS on CTW1500. + +

However, there still exists two challenges which prevent the algorithm into industry applications. On the one hand, most of the state-of-art algorithms require quadrangle bounding box which is in-accurate to locate the texts with arbitrary shape. On the other hand, two text instances which are close to each other may lead to a false detection which covers both instances. Traditionally, the segmentation-based approach can relieve the first problem but usually fail to solve the second challenge. To address these two challenges, in this paper, we propose a novel Progressive Scale Expansion Network (PSENet), which can precisely detect text instances with arbitrary shapes. More specifically, PSENet generates the different scale of kernels for each text instance, and gradually expands the minimal scale kernel to the text instance with the complete shape. Due to the fact that there are large geometrical margins among the minimal scale kernels, our method is effective to split the close text instances, making it easier to use segmentation-based methods to detect arbitrary-shaped text instances. Extensive experiments on CTW1500, Total-Text, ICDAR 2015 and ICDAR 2017 MLT validate the effectiveness of PSENet. Notably, on CTW1500, a dataset full of long curve texts, PSENet achieves a F-measure of 74.3% at 27 FPS, and our best F-measure (82.2%) outperforms state-of-art algorithms by 6.6%. The code will be released in the future. + +

Shapes](https://arxiv.org/abs/1807.01544) + + + +## Abstract + +Driven by deep neural networks and large scale datasets, scene text detection methods have progressed substantially over the past years, continuously refreshing the performance records on various standard benchmarks. However, limited by the representations (axis-aligned rectangles, rotated rectangles or quadrangles) adopted to describe text, existing methods may fall short when dealing with much more free-form text instances, such as curved text, which are actually very common in real-world scenarios. To tackle this problem, we propose a more flexible representation for scene text, termed as TextSnake, which is able to effectively represent text instances in horizontal, oriented and curved forms. In TextSnake, a text instance is described as a sequence of ordered, overlapping disks centered at symmetric axes, each of which is associated with potentially variable radius and orientation. Such geometry attributes are estimated via a Fully Convolutional Network (FCN) model. In experiments, the text detector based on TextSnake achieves state-of-the-art or comparable performance on Total-Text and SCUT-CTW1500, the two newly published benchmarks with special emphasis on curved text in natural images, as well as the widely-used datasets ICDAR 2015 and MSRA-TD500. Specifically, TextSnake outperforms the baseline on Total-Text by more than 40% in F-measure. + +

Recognition](https://arxiv.org/abs/2103.06495) + + + +## Abstract + +Linguistic knowledge is of great benefit to scene text recognition. However, how to effectively model linguistic rules in end-to-end deep networks remains a research challenge. In this paper, we argue that the limited capacity of language models comes from: 1) implicitly language modeling; 2) unidirectional feature representation; and 3) language model with noise input. Correspondingly, we propose an autonomous, bidirectional and iterative ABINet for scene text recognition. Firstly, the autonomous suggests to block gradient flow between vision and language models to enforce explicitly language modeling. Secondly, a novel bidirectional cloze network (BCN) as the language model is proposed based on bidirectional feature representation. Thirdly, we propose an execution manner of iterative correction for language model which can effectively alleviate the impact of noise input. Additionally, based on the ensemble of iterative predictions, we propose a self-training method which can learn from unlabeled images effectively. Extensive experiments indicate that ABINet has superiority on low-quality images and achieves state-of-the-art results on several mainstream benchmarks.

In particular, perspective text and curved text are common in natural scenes and are difficult to recognize. In this work, we introduce ASTER, an end-to-end neural network model that comprises a rectification network and a recognition network. The rectification network adaptively transforms an input image into a new one, rectifying the text in it. It is powered by a flexible Thin-Plate Spline transformation which handles a variety of text irregularities and is trained without human annotations. The recognition network is an attentional sequence-to-sequence model that predicts a character sequence directly from the rectified image. The whole model is trained end to end, requiring only images and their groundtruth text. Through extensive experiments, we verify the effectiveness of the rectification and demonstrate the state-of-the-art recognition performance of ASTER. Furthermore, we demonstrate that ASTER is a powerful component in end-to-end recognition systems, for its ability to enhance the detector. + +

In this paper, we investigate the problem of scene text recognition, which is among the most important and challenging tasks in image-based sequence recognition. A novel neural network architecture, which integrates feature extraction, sequence modeling and transcription into a unified framework, is proposed. Compared with previous systems for scene text recognition, the proposed architecture possesses four distinctive properties: (1) It is end-to-end trainable, in contrast to most of the existing algorithms whose components are separately trained and tuned. (2) It naturally handles sequences in arbitrary lengths, involving no character segmentation or horizontal scale normalization. (3) It is not confined to any predefined lexicon and achieves remarkable performances in both lexicon-free and lexicon-based scene text recognition tasks. (4) It generates an effective yet much smaller model, which is more practical for real-world application scenarios. The experiments on standard benchmarks, including the IIIT-5K, Street View Text and ICDAR datasets, demonstrate the superiority of the proposed algorithm over the prior arts. Moreover, the proposed algorithm performs well in the task of image-based music score recognition, which evidently verifies the generality of it. + +

However, such methods suffer from attention-drift problem because high similarity among encoded features leads to attention confusion under the RNN-based local attention mechanism. Moreover, RNN-based methods have low efficiency due to poor parallelization. To overcome these problems, we propose the MASTER, a self-attention based scene text recognizer that (1) not only encodes the input-output attention but also learns self-attention which encodes feature-feature and target-target relationships inside the encoder and decoder and (2) learns a more powerful and robust intermediate representation to spatial distortion, and (3) owns a great training efficiency because of high training parallelization and a high-speed inference because of an efficient memory-cache mechanism.

Existing methods mainly adopt recurrence or convolution based networks. Though have obtained good performance, these methods still suffer from two limitations: slow training speed due to the internal recurrence of RNNs, and high complexity due to stacked convolutional layers for long-term feature extraction. This paper, for the first time, proposes a no-recurrence sequence-to-sequence text recognizer, named NRTR, that dispenses with recurrences and convolutions entirely. NRTR follows the encoder-decoder paradigm, where the encoder uses stacked self-attention to extract image features, and the decoder applies stacked self-attention to recognize texts based on encoder output. NRTR relies solely on self-attention mechanism thus could be trained with more parallelization and less complexity. Considering scene image has large variation in text and background, we further design a modality-transform block to effectively transform 2D input images to 1D sequences, combined with the encoder to extract more discriminative features. NRTR achieves state-of-the-art or highly competitive performance on both regular and irregular benchmarks, while requires only a small fraction of training time compared to the best model from the literature (at least 8 times faster). + +

However, it performs poorly on contextless texts (e.g., random character sequences) which is unacceptable in most of real application scenarios. In this paper, we first deeply investigate the decoding process of the decoder. We empirically find that a representative character-level sequence decoder utilizes not only context information but also positional information. Contextual information, which the existing approaches heavily rely on, causes the problem of attention drift. To suppress such side-effect, we propose a novel position enhancement branch, and dynamically fuse its outputs with those of the decoder attention module for scene text recognition. Specifically, it contains a position aware module to enable the encoder to output feature vectors encoding their own spatial positions, and an attention module to estimate glimpses using the positional clue (i.e., the current decoding time step) only. The dynamic fusion is conducted for more robust feature via an element-wise gate mechanism. Theoretically, our proposed method, dubbed \\emph{RobustScanner}, decodes individual characters with dynamic ratio between context and positional clues, and utilizes more positional ones when the decoding sequences with scarce context, and thus is robust and practical. Empirically, it has achieved new state-of-the-art results on popular regular and irregular text recognition benchmarks while without much performance drop on contextless benchmarks, validating its robustness in both contextual and contextless application scenarios. + +

In this work, we propose an easy-to-implement strong baseline for irregular scene text recognition, using off-the-shelf neural network components and only word-level annotations. It is composed of a 31-layer ResNet, an LSTM-based encoder-decoder framework and a 2-dimensional attention module.

While there have been great advances in STR methods, current methods still fail to recognize texts in arbitrary shapes, such as heavily curved or rotated texts, which are abundant in daily life (e.g. restaurant signs, product labels, company logos, etc). This paper introduces a novel architecture to recognizing texts of arbitrary shapes, named Self-Attention Text Recognition Network (SATRN), which is inspired by the Transformer. SATRN utilizes the self-attention mechanism to describe two-dimensional (2D) spatial dependencies of characters in a scene text image. Exploiting the full-graph propagation of self-attention, SATRN can recognize texts with arbitrary arrangements and large inter-character spacing. As a result, SATRN outperforms existing STR models by a large margin of 5.7 pp on average in "irregular text" benchmarks. We provide empirical analyses that illustrate the inner mechanisms and the extent to which the model is applicable (e.g. rotated and multi-line text). We will open-source the code. + +

This hybrid architecture, although accurate, is complex and less efficient. In this study, we propose a Single Visual model for Scene Text recognition within the patch-wise image tokenization framework, which dispenses with the sequential modeling entirely. The method, termed SVTR, firstly decomposes an image text into small patches named character components. Afterward, hierarchical stages are recurrently carried out by component-level mixing, merging and/or combining. Global and local mixing blocks are devised to perceive the inter-character and intra-character patterns, leading to a multi-grained character component perception. Thus, characters are recognized by a simple linear prediction. Experimental results on both English and Chinese scene text recognition tasks demonstrate the effectiveness of SVTR. SVTR-L (Large) achieves highly competitive accuracy in English and outperforms existing methods by a large margin in Chinese, while running faster. In addition, SVTR-T (Tiny) is an effective and much smaller model, which shows appealing speed at inference. + +

Our contributions are three-fold: 1) For the first time, we adaptively fit arbitrarily-shaped text by a parameterized Bezier curve. 2) We design a novel BezierAlign layer for extracting accurate convolution features of a text instance with arbitrary shapes, significantly improving the precision compared with previous methods. 3) Compared with standard bounding box detection, our Bezier curve detection introduces negligible computation overhead, resulting in superiority of our method in both efficiency and accuracy. Experiments on arbitrarily-shaped benchmark datasets, namely Total-Text and CTW1500, demonstrate that ABCNet achieves state-of-the-art accuracy, meanwhile significantly improving the speed. In particular, on Total-Text, our realtime version is over 10 times faster than recent state-of-the-art methods with a competitive recognition accuracy. + +

Comprehensive experiments conducted on various bilingual (English and Chinese) benchmark datasets demonstrate that ABCNet v2 can achieve state-of-the-art performance while maintaining very high efficiency. + +

For the first time, we demonstrate that training scene text spotting models can be achieved with an extremely low-cost annotation of a single-point for each instance. We propose an end-to-end scene text spotting method that tackles scene text spotting as a sequence prediction task. Given an image as input, we formulate the desired detection and recognition results as a sequence of discrete tokens and use an auto-regressive Transformer to predict the sequence. The proposed method is simple yet effective, which can achieve state-of-the-art results on widely used benchmarks. Most significantly, we show that the performance is not very sensitive to the positions of the point annotation, meaning that it can be much easier to be annotated or even be automatically generated than the bounding box that requires precise positions. We believe that such a pioneer attempt indicates a significant opportunity for scene text spotting applications of a much larger scale than previously possible. + +

+ +## Usage + + + +### Prerequisites + +- Python 3.7 +- PyTorch 1.6 or higher +- [MIM](https://github.com/open-mmlab/mim) +- [MMOCR](https://github.com/open-mmlab/mmocr) + +All the commands below rely on the correct configuration of `PYTHONPATH`, which should point to the project's directory so that Python can locate the module files. In `SPTS/` root directory, run the following line to add the current directory to `PYTHONPATH`: + +```shell +# Linux +export PYTHONPATH=`pwd`:$PYTHONPATH +# Windows PowerShell +$env:PYTHONPATH=Get-Location +``` + +### Dataset + +As of now, the implementation uses datasets provided by SPTS for **pre-training**, and uses MMOCR's datasets for **fine-tuning and testing**. It's because the test split of SPTS's datasets does not contain enough information for e2e evaluation; and MMOCR's dataset preparer has not yet supported all the datasets used in SPTS. *We are working on this issue, and they will be available in MMOCR's dataset preparer very soon.* + +Please follow these steps to prepare the datasets: + +- Download and extract all the SPTS datasets into `spts-data/` following [SPTS official guide](https://github.com/shannanyinxiang/SPTS#dataset). + +- Use [Dataset Preparer](https://mmocr.readthedocs.io/en/dev-1.x/user_guides/data_prepare/dataset_preparer.html) to prepare `icdar2013`, `icdar2015` and `totaltext` for `textspotting` task. + + ```shell + # Run in MMOCR's root directory + python tools/dataset_converters/prepare_dataset.py icdar2013 icdar2015 totaltext --task textspotting + ``` + + Then create a soft link to `data/` directory in the project root directory: + + ```shell + ln -s ../../data/ . + ``` + +### Training commands + +In the current directory, run the following command to train the model: + +#### Pretrain + +```bash +mim train mmocr config/spts/spts_resnet50_8xb8-150e_pretrain-spts.py --work-dir work_dirs/ --amp +``` + +To train on multiple GPUs, e.g. 8 GPUs, run the following command: + +```bash +mim train mmocr config/spts/spts_resnet50_8xb8-150e_pretrain-spts.py --work-dir work_dirs/ --launcher pytorch --gpus 8 --amp +``` + +#### Finetune + +Similarly, run the following command to finetune the model on a dataset (e.g. icdar2013): + +```bash +mim train mmocr config/spts/spts_resnet50_8xb8-200e_icdar2013.py --work-dir work_dirs/ --cfg-options "load_from={CHECKPOINT_PATH}" --amp +``` + +To finetune on multiple GPUs, e.g. 8 GPUs, run the following command: + +```bash +mim train mmocr config/spts/spts_resnet50_8xb8-200e_icdar2013.py --work-dir work_dirs/ --launcher pytorch --gpus 8 --cfg-options "load_from={CHECKPOINT_PATH}" --amp +``` + +### Testing commands + +In the current directory, run the following command to test the model on a dataset (e.g. icdar2013): + +```bash +mim test mmocr config/spts/spts_resnet50_8xb8-200e_icdar2013.py --work-dir work_dirs/ --checkpoint ${CHECKPOINT_PATH} +``` + +## Convert Weights from Official Repo + +Users may download the weights from [SPTS](https://github.com/shannanyinxiang/SPTS#inference) and use the conversion script to convert them into MMOCR format. + +```bash +python tools/ckpt_adapter.py [SPTS_WEIGHTS_PATH] [MMOCR_WEIGHTS_PATH] +``` + +## Results + +All the models are trained on 8x A100 GPUs with AMP on (`--amp`).

Assuming that we are developing a project X and the core modules are placed under `projects/X/modules`, then simply adding `custom_imports = dict(imports='projects.X.modules')` to the config allows us to debug from usual entrypoints (e.g. `tools/train.py`) from the root directory of the algorithm library.
