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.

Key words: video retrieval, motion vector, semantic annotation

摘要: 提出了一种新的压缩视频中对主要运动进行定性分析算法,该算法主要应用于视频信息检索。依据运动矢量的方向分布特性和运动矢量之间的相对关系来判断主要运动类型,可以直接用于有运动矢量信息的压缩视频流检索上。
