This paper focuses on soccer ball tracking which is known to be more difficult than that of players due to its small size in an image and abrupt changes in its motion. Suggested is an effective soccer ball tracking algorithm which estimates ball position by exploiting the background image and player tracking results. In other words, the trajectory of ball is derived as image blobs by eliminating player blobs and the background parts from an image sequence. This algorithm performed well on a pretty long TV broadcast sequence in which the ball is frequently occluded by players.
