Tracking football player movement from a single moving camera using particle filters

This paper deals with the problem of tracking football players in a football match using data from a single mov-ing camera. Tracking footballers from a single video source is difficult: not only do the football players oc-clude each other, but they frequently enter and leave the camera's field of view, making initialisation and de-struction of a player's tracking a difficult task. The sys-tem presented here uses particle filters to track players. The multiple state estimates used by a particle filter provide an elegant method for maintaining tracking of players following an occlusion. Automated tracking can be achieved by creating and stopping particle filters de-pending on the input player data.
