Control System Design and Simulation for Video Tracking

Abstract

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.
