Abstract: This paper discusses some sudden scene change detection algorithms used for content-based video indexing and retrievaling,and proposesa new algorithm for compressed domain abrupt transitions. Test result proves that the algorithm isn't constrained by the limitation of video category andmay get satisfying result.
