v29 Key Fixes
yolov8n instead of s-pose
3× faster inference, sufficient for player bounding boxes.

Tribune exclusion zone
Top 22% of frame is a hard-drop zone — crowd is never tracked as players.

Optical flow homography
Lucas-Kanade LK on grass feature points instead of slow Python RANSAC. Fast and smooth.

Output at 12 FPS
Skips source frames so the GPU has more time per processed frame.

Higher CONF_PERSON = 0.35
Reduces false detections on advertising boards and spectators.
