WPose = 0.25Validation through EPTS devices in youth games. In the presented experiments:
Output line’s length: proportional to the associated
pose-field-ball confidences
Practical Applications
Detection Rate: 89.69 % LR-Side Deviation: 92.43 % Mean Absolute Error: 40.00º Median Absolute Error: 34.07º
Orientation Assessment through Video
Evaluation of On-Ball and Off-Ball Direction
Refining Pass-Probability / Pitch-Control Models
Reaction Time Measurement
WPos = 0.15 WBall = 0.6
