ByteTrack
Multi-object tracking by associating every detection box, including the low-confidence ones everyone else throws away.
About
ByteTrack's insight is simple: most trackers discard low-confidence detections, but those boxes often contain real occluded objects. BYTE associates nearly every detection box, matching high-score boxes to tracklets first, then using low-score boxes to recover true objects and filter background. Paired with a plain YOLOX detector and a Kalman motion model, with no ReID network and no attention, it set a new state of the art.
The authors report 80.3 MOTA, 77.3 IDF1, and 63.1 HOTA on MOT17 at 30 FPS on a single V100, plus SOTA on MOT20, HiEve, and BDD100K. MIT-licensed and dependency-light, ByteTrack became the default tracking baseline in production systems and the association method ported into countless trackers. If your tracker keeps losing people behind each other, this is usually the first fix to try.

Benchmarks
Author-reported: 80.3 MOTA / 77.3 IDF1 / 63.1 HOTA on MOT17 test at 30 FPS on V100; SOTA on MOT20, HiEve, BDD100K
Provider-reported unless a source says otherwise. Benchmarks are marketing-adjacent by nature — treat them as directional.
Use cases
Trust score — 8/10
Scored 8/10 (verified tier, metrics-v1). Evidence: ECCV 2022 paper (arXiv:2110.06864) with MOT17/MOT20 numbers confirmed via the official repo README; MIT license confirmed via multiple third-party attributions and the Roboflow model page. Strengths: deceptively simple idea with huge practical impact, permissive license, widely deployed. Docked for: (1) tracking quality is bounded by the underlying detector; (2) no appearance model, so long occlusions still break identity. License: MIT.
