# VegAnn Dataset
### **Vegetation Annotation of a large multi-crop RGB Dataset acquired under diverse conditions for image semantic segmentation**
## Keypoints ⏳
- VegAnn contains 3775 images
- Images are 512*512 pixels
- Corresponding binary masks is 0 for soil + crop residues (background) 255 for Vegetation (foreground)
- The dataset includes images of 26+ crop species, which are not evenly represented
- VegAnn was compiled using a variety of outdoor images captured with different acquisition systems and configurations
- For more information about VegAnn, details, labeling rules and potential uses see https://doi.org/10.1038/s41597-023-02098-y
## Dataset Description 📚
VegAnn, short for Vegetation Annotation, is a meticulously curated collection of 3,775 multi-crop RGB images aimed at enhancing research in crop vegetation segmentation. These images span various phenological stages and were captured using diverse systems and platforms under a wide range of illumination conditions. By aggregating sub-datasets from different projects and institutions, VegAnn represents a broad spectrum of measurement conditions, crop species, and development stages.
### Languages 🌐
The annotations and documentation are primarily in English.
## Dataset Structure 🏗
### Data Instances 📸
A VegAnn data instance consists of a 512x512 pixel RGB image patch derived from larger raw images. These patches are designed to provide sufficient detail for distinguishing between vegetation and background, crucial for applications in semantic segmentation and other forms of computer vision analysis in agricultural contexts.

### Data Fields 📋
- `Name`: Unique identifier for each image patch.
- `System`: The imaging system used to acquire the photo (e.g., Handheld Cameras, DHP, UAV).
- `Orientation`: The camera's orientation during image capture (e.g., Nadir, 45 degrees).
- `latitude` and `longitude`: Geographic coordinates where the image was taken.
- `date`: Date of image acquisition.
- `LocAcc`: Location accuracy flag (1 for high accuracy, 0 for low or uncertain accuracy).
- `Species`: The crop species featured in the image (e.g., Wheat, Maize, Soybean).
- `Owner`: The institution or entity that provided the image (e.g., Arvalis, INRAe).
- `Dataset-Name`: The sub-dataset or project from which the image originates (e.g., Phenomobile, Easypcc).
- `TVT-split1` to `TVT-split5`: Fields indicating the train/validation/test split configurations, facilitating various experimental setups.
### Data Splits 📊
The dataset is structured into multiple splits (as indicated by `TVT-split` fields) to support different training, validation, and testing scenarios in machine learning workflows.
## Dataset Creation 🛠
### Curation Rationale 🤔
The VegAnn dataset was developed to address the gap in available datasets for training convolutional neural networks (CNNs) for the task of semantic segmentation in real-world agricultural environments. By incorporating images from a wide array of conditions and stages of crop development, VegAnn aims to enhance the performance of segmentation algorithms, promote benchmarking, and foster research on large-scale crop vegetation segmentation.
### Source Data 🌱
#### Initial Data Collection and Normalization
Images within VegAnn were sourced from various sub-datasets contributed by different institutions, each under specific acquisition configurations. These were then standardized into 512x512 pixel patches to maintain consistency across the dataset.
#### Who are the source data providers?
The data was provided by a collaboration of institutions including Arvalis, INRAe, The University of Tokyo, University of Queensland, NEON, and EOLAB, among others.

### Annotations 📝
#### Annotation process
Annotations for the dataset were focused on distinguishing between vegetation and background within the images. The process ensured that the images offered sufficient spatial resolution to allow for accurate visual segmentation.
#### Who are the annotators?
The annotations were performed by a team comprising researchers and domain experts from the contributing institutions.
## Considerations for Using the Data 🤓
### Social Impact of Dataset 🌍
The VegAnn dataset is expected to significantly impact agricultural research and commercial applications by enhancing the accuracy of crop monitoring, disease detection, and yield estimation through improved vegetation segmentation techniques.
### Discussion of Biases 🧐
Given the diverse sources of the images, there may be inherent biases towards certain crop types, geographical locations, and imaging conditions. Users should consider this diversity in applications and analyses.

abstract = {Applying deep learning to images of cropping systems provides new knowledge and insights in research and commercial applications. Semantic segmentation or pixel-wise classification, of RGB images acquired at the ground level, into vegetation and background is a critical step in the estimation of several canopy traits. Current state of the art methodologies based on convolutional neural networks (CNNs) are trained on datasets acquired under controlled or indoor environments. These models are unable to generalize to real-world images and hence need to be fine-tuned using new labelled datasets. This motivated the creation of the VegAnn - Vegetation Annotation - dataset, a collection of 3775 multi-crop RGB images acquired for different phenological stages using different systems and platforms in diverse illumination conditions. We anticipate that VegAnn will help improving segmentation algorithm performances, facilitate benchmarking and promote large-scale crop vegetation segmentation research.},
