Multiple interacting targets tracking with application to team sports

Abstract

The interest in the field of computer aided analysis of sport events is ever growing and the ability of tracking objects during a sport event has become an elementary task for nearly every sport analysis system. We present in this paper a color based probabilistic tracker that is suitable for tracking players on the playground during a sport game. Since the players are being tracked in their natural environment and this environment is subjected to certain rules of the game, we use the concept of closed worlds, to model the scene context and thus improve the reliability of tracking.
