| Abstract: | Recent advances in multimedia compression technology,have led to widespread use and availability of digital compressed video(e. g. MPEG). Working in the compressed domain offers the following advantages. first, by not having to perform decoding/re-encoding, computational complexity is reduced. Second, operations are faster due to the lower data rate of compressed video. This paper describes an approach of MPEG video indexing,including shot change detection, Camera Operation Recognition and key frames extraction. |
