Abstract
Due to the increasing amount of information carried by video, video analysis that clips video as changed scenes or key-frames becomes essential for efficient video indexing. In this paper, we proposed a compressed domain scene change detection and camera motion characterization algorithm. We believe that the most vital inherent information hided in the MPEG bitstream, which can aid scene shot and sub-shot detection, are the motion vector and the macroblock type statistics. We evaluate the results of the scene change detection and camera motion characterization to get the accurate shot and sub-shot location.
