Player tracking in soccer broadcast videos can be further processed by coaches and experts to judge weaknesses and strengths of the players and the team. Following player detection by Adaboost, player labeling, occlusion handling and player localization, player trajectory is extracted using combination of graph with artificial bee colony (ABC) and particle swarm optimization (PSO) in this research. PSO and ABC are optimization method inspired by the flocking behavior of birds and bees which were originally customized for continuous function value optimization. However, the need for modifying the discrete version in different applications is inevitable. In this paper, a modified version of discrete PSO and ABC for player tracking is proposed. Moreover, a new method for registering frames to the field model based on line recognition is proposed to diminish the search space. Finally, the proposed algorithm is tested on seven shots from six different soccer broadcast videos. Experimental results show the capability of the proposed method for extracting player trajectory in soccer broadcast videos.
