To discover important but previously unknown information in video sequences, a discovery method of unknown visual information based on target tracking is proposed in this paper. It provides a worthy approach for support decision. The proposed discovery method analyzes the video using target tracking. This method, adopting detection and correspondence of feature points, target identification and tracking, and target occlusion techniques etc, analyzes video sequences. In the video, using above techniques, we not only study the spatiotemporal rela...
