Contact: [ππ»ββοΈCheng-Yen (Wesley) Hsieh](https://wesleyhsieh0806.github.io/) ## Dataset Description Our dataset augments the TAO dataset with amodal bounding box annotations for fully invisible, out-of-frame, and occluded objects. Note that this implies TAO-Amodal also includes modal segmentation masks (as visualized in the color overlays above). Our dataset encompasses 880 categories, aimed at assessing the occlusion reasoning capabilities of current trackers through the paradigm of Tracking Any Object with Amodal perception (TAO-Amodal). ### Dataset Download 1. Download all the annotations. ```bash git lfs install git clone git@hf.co:datasets/chengyenhsieh/TAO-Amodal ``` 2. Download all the video frames: You can either download the frames following the instructions [here](https://motchallenge.net/tao_download.php) (recommended) or modify our provided [script](./download_TAO.sh) and run ```bash bash download_TAO.sh ``` ## π Dataset Structure The dataset should be structured like this: ```bash βββ frames βββ train βββ ArgoVerse βββ BDD βββ Charades βββ HACS βββ LaSOT βββ YFCC100M βββ amodal_annotations βββ train/validation/test.json βββ train_lvis_v1.json βββ validation_lvis_v1.json βββ example_output βββ prediction.json βββ BURST_annotations βββ train βββ train_visibility.json ``` ## π File Descriptions | File Name | Description | | ------------------ | ---------------------------------- | | train/validation/test.json | Formal annotation files. We use these annotations for visualization. Categories include those in [lvis](https://www.lvisdataset.org/) v0.5 and freeform categories. | | train_lvis_v1.json | We use this file to train our [amodal-expander](https://tao-amodal.github.io/index.html#Amodal-Expander), treating each image frame as an independent sequence. Categories are aligned with those in lvis v1.0. | | validation_lvis_v1.json | We use this file to evaluate our [amodal-expander](https://tao-amodal.github.io/index.html#Amodal-Expander). Categories are aligned with those in lvis v1.0. | | prediction.json | Example output json from amodal-expander. Tracker predictions should be structured like this file to be evaluated with our [evaluation toolkit](https://github.com/WesleyHsieh0806/TAO-Amodal?tab=readme-ov-file#bar_chart-evaluation). | | BURST_annotations/XXX.json | Modal mask annotations from [BURST dataset](https://github.com/Ali2500/BURST-benchmark) with our heuristic visibility attributes. We provide these files for the convenience of visualization | ### Annotation and Prediction Format Our annotations are structured similarly as [TAO](https://github.com/TAO-Dataset/annotations) with some modifications. Annotations: ```bash Annotation file format: { "info" : info, "images" : [image], "videos": [video], "tracks": [track], "annotations" : [annotation], "categories": [category], "licenses" : [license], } annotation: { "id": int, "image_id": int, "track_id": int, "bbox": [x,y,width,height], "area": float, # Redundant field for compatibility with COCO scripts "category_id": int, "video_id": int, # Other important attributes for evaluation on TAO-Amodal "amodal_bbox": [x,y,width,height], "amodal_is_uncertain": bool, "visibility": float, (0.~1.0) } image, info, video, track, category, licenses, : Same as TAO ``` Predictions should be structured as: ```bash [{ "image_id" : int, "category_id" : int, "bbox" : [x,y,width,height], "score" : float, "track_id": int, "video_id": int }] ``` Refer to the instructions of [TAO dataset](https://github.com/TAO-Dataset/tao/blob/master/docs/evaluation.md) for further details ## πΊ Example Sequences Check [here](https://tao-amodal.github.io/#TAO-Amodal) for more examples and [here](https://github.com/WesleyHsieh0806/TAO-Amodal?tab=readme-ov-file#artist-visualization) for visualization code.
