Poor-Performing Class: Ball
|
| 97 |
The ball class is the weakest performer (mAP@50 = 0.72) because the ball is typically only 10-20 pixels across at broadcast resolution and moves at 80-100 mph, causing motion blur in standard 30fps footage. Background crowd balls and logos also created false positives requiring manual cleanup.
