英文摘要	Conference Name:2013 38th IEEE International Conference on Acoustics, Speech, and Signal Processing, ICASSP 2013. Conference Address: Vancouver, BC, Canada. Time:May 26, 2013 - May 31, 2013.; IEE Signal Processing Society; The sparse representation has been widely used in many areas including visual tracking. The part-based representation performs outstandingly by using non-holistic templates to against occlusion. This paper combined them and proposed a robust object tracking method using part-based sparsity model for tracking an object in a video sequence. In the proposed model, one object is represented by image patches. The candidates of these patches are sparsely represented in the space which is spanned by the patch templates and trivial templates. The part-based method takes the spatial information of each patch into consideration, where the vote maps of multiple patches are used. Furthermore, the update scheme keeps the representative templates of each part dynamically. Therefore, trackers can effectively deal with the changes of appearances and heavy occlusion. On various public benchmark videos, the abundant results of experiments demonstrate that the proposed tracking method outperforms many existing state-of-the-arts algorithms. ? 2013 IEEE.
