    When objects undergo large pose change, illumination variation or partial occlusion, most existed visual tracking algorithms tend to drift away from targets and even fail in tracking them. To address this issue, in this paper we propose an online algorithm by combining Incremental Learning (IL) and Multiple Instance Learning (MIL) based on local sparse representation for tracking an object in a vi...

    In this paper a novel denoising algorithm based on partial differential equation variational approach is proposed. The proposed algorithm is obtained by weighted combinations of the an isotropic diffusion model and total variation model. Experimental results show that our new approach is more efficient in image denoising than both an isotropic diffusion and total variation in terms of preserving e... View full abstract»

    Trajectory features have recently shown promising results to action recognition in video. Typically, they are extracted by tracking feature points with the KLT tracker or matching SIFT descriptors between frames. However, trajectory can be due to the action of interest, but also be caused by background or the camera motion. To overcome the problem, human detection is applied to roughly estimate of...
