State: [cx, cy, w, h, vcx, vcy, vw, vh] — bounding-box centre, size, and their velocities. Models each track as a constant-velocity system. Position noise is scaled proportionally to bounding-box size ...

Abstract: To address issues such as missed detections and false positives in safety equipment wear detection tasks caused by complex backgrounds, severe occlusions, and small target sizes, as well as ...
