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.
