We take depth recovery using face priors as the starting point of semantic prior guided depth recovery for non-rigid objects.We developed a joint optimization framework for employing face priors for depth recovery.Experimental results on BU4DFE dataset verified the effectiveness of the proposed method. For repairing inaccurate depth measurements from commodity ...

Considering that the existing depth recovery approaches have different limitations when applied to Kinect depth data, in this article, we propose to integrate their effective features including adaptive support region selection, reliable depth selection, and color guidance together under an optimization framework for Kinect depth recovery. In particular, we formulate ...

We propose to apply low-rank and sparse decomposition (LRSD) for video compression.We propose an incremental LRSD (ILRSD) which facilities large-scale video processing.Our method achieves better coding efficiency compared to the state-of-the-art. Videos captured by stationary cameras are usually with a static or gradually changed background. Existing schemes are not able ...

Surveillance videos are usually with a static or gradually changed background. The state-of-the-art block-based codec, H.264/AVC, is not sufficiently efficient for encoding surveillance videos since it cannot exploit the strong background temporal redundancy in a global manner. In this paper, motivated by the recent advance on low-rank and sparse decomposition ...
Keywords: low-rank and sparse decomposition, cur decomposition, surveillance video compression
