A logic reasoning model based method is proposed in this paper for object tracking in compressed domain. First, the object is defined by the motion detector. Then, the supposed target trajectory and predicted position are estimated by the direction angle and the intensity within motion field. The possible conditions of lost, stop or occlusion are determined by logic and reasoning analysis and handled by the direction angle and the intensity in motion field. The outperformance of our method on reducing loss rate and enhancing the trajectory fit has been demonstrated by the experiments. The accurate object tracking result of the proposed method is presented as well.
