博士 === 元智大學 === 電機工程研究所 === 89 === This paper presents a novel approach to track multiple moving objects using the Level-set method. First, in order to overcome the problem of camera motion, a block matching method is used to estimate the information of camera motion for background compensation. Then, the difference image is obtained by subtracting two adjacent frames. With the difference image, different moving objects can be detected using the Level-set method. Furthermore, a Gaussian object model is used to remove object shadows. Finally, through connected component analysis, an object-relation table is created to track all the detected objects efficiently. Experimental results show that the proposed method is much robust and powerful than other traditional methods.
