     searching for specific targets from surveillance videos requires huge workforce due to a surveillance system usually generates great amounts of video data. to alleviate the effort of human analysis, a system that helps users quickly look for targets of interest is highly demanded. in this paper, we propose a browsing and retrieval system for users to quickly locate desired targets in surveillance videos. our basic idea is to collect all moving objects, which carry the most significant information in surveillance videos, to construct a corresponding compact video. the temporal coordinates of the moving objects in the compact video are rearranged, therefore increasing the compactness of the video. however, the appearing order of the moving objects is kept to preserve the essential activities involved in the original surveillance video. using our system, users will spend only several minutes watching the compact video instead of hours monitoring a long surveillance video. we conducted experiments to demonstrate that the proposed system can help users quickly look for specific targets in surveillance videos.
