Take your eyes off the ball: Improving ball-tracking by focusing on team play

Xinchao Wang, Vitaly Ablavsky, Horesh Ben Shitrit, Pascal Fua
2014 Computer Vision and Image Understanding  
Accurate video-based ball tracking in team sports is important for automated game analysis, and has proven very difficult because the ball is often occluded by the players.  ...  In this paper, we propose a novel approach to addressing this issue by formulating the tracking in terms of deciding which player, if any, M is in possession of the ball at any given time.  ...  Given the motion context, the target's location was implemented as a linear regression with respect to the motion of the contextual objects.  ...
