Many existing security-systems consist of CCTV-Cameras, which record data streams and store it on a large storage medium. After any security incident occurred, the video material has to be manually reviewed by a human operator. If the exact time of the incident is unknown, the material to be reviewed can be rather long and the examination becomes very time consuming. Typically the most interesting content is sparsely distributed along the video. Hence, most of the reviewing time is wasted. Moreover, through the long irrelevant parts of the video material the attention of the operator decreases and therefore important events could be missed. Video synopsis by constant action movie (CAM) offers a solution to this problem: The human operator only has to inspect (possibly) relevant parts of the video. The key idea of the proposed CAM approach is to time-compress the video stream, so that the interesting content is equally distributed (constant action) along the video.
