摘　　要：In this paper,we propose a novel visual tracking method using a discriminative representation under a Bayesian framework.First,we exploit the histogram of gradient (HOG)to generate the texture features of the target templates and candidates.Second,we introduce a novel discriminative representation and l2-regularized least squares method to solve the proposed representation model.The proposed model has a closed-form solution and very high computational efficiency.Third,a novel likelihood function and an update scheme considering the occlusion factor are adopted to improve the tracking performance of our proposed method. Both qualitative and quantitative evaluations on 15 challenging video sequences demonstrate that our method can achieve more robust tracking results in terms of the overlap rate and center location error.
