| Abstract: | A qualitative analysis method of dominant motion for video retrieval about scheme compressed video stream based on the directional distribution of motion vectors and the feature of the relationship between any two motion vectors in MPEG2 stream is proposed.The reliable estimation of dominant motion is obtained from this compressed stream processing algorithm.The application of the video retrieve is workable and the performance is robust and accurate. |
