In this paper, we propose a novel method to track non-rigid and/or articulated objects using superpixel matching and markov random field (MRF). Our algorithm consists of three stages. First, a superpixel dataset is constructed by segmenting training frames into superpixels, and each superpixel is represented by multiple features. The appearance information of target is encoded in the superpixel database. Second, each new frame is segmented into superpixels and then its object-background confidence map is derived by comparing its superpixels with k-nearest neighbors in superpixel dataset. Taking context information into account, we utilize MRF to further improve the accuracy of confidence map. In addition, the local context information is incorporated through a feedback to refine superpixel matching. In the last stage, visual tracking is achieved via finding the best candidate by maximum a posterior …
