Usage

Install the TrackFish3D code from:

• https://github.com/pattgene/TrackFish3D

Example inference command:

python infer.py \
  /path/to/best_ckpt.pth \
  /path/to/scene.json \
  /path/to/scene-images \
  --no_dino \
  --output outputs/scene.txt

Example evaluation command:

python evaluate.py \
  --pred outputs/test1.txt \
  --gt /path/to/synfish/test/gt-traj/test1-gt.csv \
  --match_pred_range

For the released benchmark GT filenames, the evaluator selects the matching protocol automatically. For other datasets, configure the evaluation protocol explicitly.

This Hugging Face repository hosts checkpoints only. The released SynFish download is available at:

• https://drive.google.com/file/d/1Miysj51p1Qpt4J4WskqsPdmEUYFANqBD/view

After extraction, synfish/ should contain train/ and test/.
