Abstract

In basketball games, screen is a blocking move performed by an offensive player, who stands beside or behind a defender, in order to free a teammate to shoot, to receive a pass, or to drive in to score. Screen is the fundamental essence that most offensive tactics are executed with. In this paper, a screen-strategy analysis system is designed, and through combining the identified screens, what tactics are executed in basketball games can be speculated. The proposed system is capable of court region detection, camera calibration and player extraction. Player trajectories are computed by a Kalman filter-based tracking method and mapped to the real-world court coordinates. The player position/trajectory information greatly assists professional-oriented applications such as screen-strategy analysis and tactic inference. The experiments on broadcast basketball videos show encouraging results.
