VLA-ReID: Video-Level Association for Re-Identification in Multi-Object Tracking of Highly Similar Objects
Weights and precomputed assets for VLA-ReID (Video-Level Association re-ID): set-relative appearance re-scoring for multi-object tracking of highly similar objects, evaluated on the BEE24 benchmark. Frame-Common Appearance Estimation (FCAE) + Common Appearance Suppression (CAS) plug into TrackTrack by replacing only its appearance term.
BEE24 test (official 5-sequence split, shared YOLOX detections):
| Method | HOTA | MOTA | IDF1 | AssA | IDs |
|---|---|---|---|---|---|
| TrackTrack (baseline) | 48.05 | 65.69 | 64.12 | 45.91 | 606 |
| VLA-ReID (ours) | 49.22 | 67.02 | 64.93 | 46.64 | 437 |
See the GitHub repository for installation and step-by-step reproduction instructions; the file-by-file manifest (destination paths + SHA-256) is in WEIGHTS.md.
