| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 97 === Up to now, most of the digital monitoring systems only provided in the basic functions of frame recording and frame changing detection. However, the part of the object detection and tracking, when the target passes the occlusion and crosses through the moving objects, it causes the state that a part of features is covered. The study of extracting features and tracking effectively was absorbed in the digital image monitoring system.
In this paper, background model was built up in a condition that slight variations in intensity of background. The region of target is extracted with boundary of background variation is more intact than the region of target is extracted with background subtraction method. Finally, the system will track continuously incomplete target according as Particle Filter algorithmthe and codebook that includes hue and saturation of target.By the result of the experiment, when it is 90% to cover features of target on average, the system can still keep the locking of target.
