ByteTrack
ByteTrack (arXiv 2110.06864). A two-stage IoU tracker that associates every detection, not just high-confidence ones, to recover objects that are briefly occluded or partially off-screen. A strong recall improvement over SORT at minimal extra cost.

}Parameters
| Parameter | Default | Description |
|---|---|---|
track_thresh | 0.5 | Confidence threshold separating high- and low-confidence detections |
track_buffer | 30 | Frames a lost track is buffered before deletion |
match_thresh | 0.8 | Stage-1 match cutoff as a maximum IoU distance (lower is stricter) |
det_thresh | 0.6 | Minimum confidence to initialise a new track |
second_match_thresh | 0.5 | Stage-2 match cutoff for recovering low-confidence detections |
Tuning: lower track_thresh (~0.3) to feed more low-confidence detections into stage two; raise
track_buffer (~60) when the detector drops frames; lower match_thresh (~0.7) for fast-moving
objects where IoU falls off quickly.
