| Abstract(in English) | There is a need for systems that can automatically detect specific human motions in a surveillance video. However, almost all of the human motion recognition techniques proposed so far are for detecting relatively large motions within simple video sequences. To alleviate this shortcoming, we propose a method that can detect specific small motions within crowd sequences of real surveillance video. Our motion recognition method is based on the bag-of-features approach, and key-point trajectories are used as its features. The method extracts a fixed-length feature descriptor from a key-point trajectory and uses it for event classification. In addition, feature weights are calculated for reducing the interference from noise trajectories in the background regions. We confirmed the effectiveness of our proposed method in experiments comparing it with other techniques and in the TRECVID Surveillance Event Detection task. |
