🏃 Training and Inference

We augment the SOTA modal tracker GTR with Amodal Expander by fine-tuning on TAO-Amodal dataset.

Please prepare datasets and check our MODEL ZOO for training/inference instructions.

📊 Evaluation

After obtaining the prediction JSON lvis_instances_results.json through the above inference pipeline. You can evaluate the tracker results using our evaluation toolkit.

🤖 Demo

You can test our model on a single video through:

python demo.py --config-file configs/GTR_TAO_Amodal_Expander_PasteNOcclude.yaml \
               --video-input demo/input_video.mp4 \
               --output      demo/output.mp4 \
               --opts        MODEL.WEIGHTS /path/to/Amodal_Expander_PnO_45k.pth

Use --input video_folder/*.jpg instead if the video consists of image frames.

🐇 PasteNOcclude

PasteNOcclude serves as a data augmentation technique to automatically generate more occlusion scenarios. Check the Jupyter demo and implementation details (link 1, link 2, link 3).
