There is an urgent need to extract key information from video automatically for the purposes of indexing, fast retrieval, and scene analysis. To support this vision, reliable scene change detection algorithms must be developed. Several algorithms have been proposed for both sudden and gradual scenechangedetection in uncompressed and compressed video. In this paper some common algorithms that have been proposed for scenechangedetection are reviewed. A novel algorithm for sudden scenechangedetection for MPEG-2 compressed video is then presented. This uses the number of interpolated macroblocks in B-frames to identify the sudden scenechanges. A gradual scenechangedetection algorithm based on statistical features is also presented.
