A review of RTMDet (arXiv 2022): a real-time detector that reaches 52.8% COCO AP at 300+ FPS through systematic design choices rather than a new module, and extends cleanly to instance segmentation and rotated detection.

A safety-gear detector scored 0.91 mAP yet fired 'helmet_off' on helmeted workers. Here is the diagnosis, and how empty-GT negatives cut external false positives by 66% with no measured loss on the AIHub in-clip validation mAP.
