[P] motcpp; I rewrote common 9 MOT trackers in C++17 achiving 10–100× speedsup than Python implementations in my MOT17 runs!

Hi all,

I’m sharing motcpp, an open-source C++17 library for multi-object tracking (tracking multiple people/objects across video frames). It’s built for real-time speed and easier deployment than many Python-heavy pipelines.

What’s insideTrackers: SORT, ByteTrack, OC-SORT, StrongSORT, BoostTrack, UCMCTrack (and a few more)

• MOT17/MOT20 evaluation + utilities + docs
• Optional ReID Backend (appearance matching) via ONNX Runtime

Why I built it

• I needed trackers for [YOLOS-CPP]. In my benchmarks on MOT17, it runs about 10–100× faster than common Python implementations (details + scripts in the repo).

I’d love feedback on usability (API), docs, and reproducibility. If you try it, let me know your setup + results!

Cheers!
