  Abstract

Three different cases should be considered for motion tracking : moving object with fixed camera, fixed object with moving camera, and moving object with moving camera. Two methods are widely used for motion tracking : the optical flow method and the difference frame method. The optical flow method is mainly used when either one, object or camera, is fixed. This method tracks object using time-space vector which compares object position frame by frame. This method requires heavy computation, and is not suitable for real-time monitoring system such as DVR(Digital Video Recorder). The different frame method is used for moving object with fixed camera. This method tracks object by comparing the difference between background images. This method is good for real-time applications because computation is small. However, it is not applicable if the camera is moving.This thesis proposes and implements the motion tracking system using the difference frame method with PTZ(Pan-Tilt-Zoom) control. This system can be used for moving object with moving camera. Since the difference frame method is used, the system is suitable for real-time applications such as DVR.
