Control System Design and Simulation for Video Tracking

In this paper, a proposed video tracking system is introduced. The proposed system consists of two parts: motion estimation and tracking. Motion estimation is carried out by computing the difference between two successive images. The difference is dark image contains small relatively brightness at the region of existence the moving object. The average location of the moving object in the difference image is the target location, the tracking aims to make the head of camera facing the target location. Such that, the relation between the head of the camera and the target location relative to camera location is modeled to computes the deflection in the head. The tracking part depends on the head deflection, which make the control of camera motion toward the target location is modeled depending on the head deflection with regarding continual and soft motion of the camera. Such motion is made by constraint the rate of changing the head of camera at each control interval. The simulation results show reality and acceptable motion of the camera, this ensures the efficiency of the tracking method and correct proposed model
