Abstract
A method segments a compressed video by extracting audio and visual features from the compressed video. The audio features are clustered according to K-means clustering in a set of classes, and the compressed video is then partitioned into first segments according to the set of classes. The visual features are then used to partitioning each first segment into second segments using motion analysis. Summaries of the second segments can be provided to assist in the browsing of the compressed video.
