Abstract
Recently, the implementation of the automatic moving object tracking system, in various circumstances, is required to protect us from the increase of crime in our society. Background different method and Frame different method are used to extract and track moving objects from motion image sequences. But when noises occurs by the change of illumination, the extraction of the objects become unstable. Therefore, the tracking of the moving objects become difficult. In this study, a real time tracking method based on background different method, that is not affected by the noises and operate, is proposed.
