Video error concealment via total variation regularized matrix completion

In this paper, we propose a novel video error concealment method to restore the visual degradation, caused by packet loss in video delivery over unreliable channels. For a video sequence, we exploit its inherent temporal-spatially correlated property, i.e., temporal continuity and spatial smoothness, from a global view point. We then formulate it into a total variation regularized matrix completion model. Compared with the error concealment methods implemented in the H.264 reference software, our algorithm is able to achieve significantly higher PSNR as well as better visual quality.
