Background extraction from video sequences is a useful and important technique in video surveillance. This paper proposes a motion-assisted matrix completion model for background extraction from video sequences. A binary motion map is first calculated for each frame by optical flow. By excluding areas associated with moving objects with the binary motion maps, the background extraction is formulated into a motion-assisted matrix completion (MAMC) problem. Experimental results show that our method not only extracts promising backgrounds but also outperforms many state-of-the-art methods in distinguishing moving objects on challenging datasets.
