Dynamic video analysis moving target retrieval system

The invention relates to a dynamic video analysis moving target retrieval system. The dynamic video analysis moving target retrieval system comprises video coding, video object segmentation, video streaming and video retrieval, wherein the video object segmentation segments an image or a video sequence into areas according to a certain standard, the video coding and the video retrieval are carried out on the segmented image or video sequence, digital information after the video coding is transmitted to the video streaming after the bases of storage, playing and transmission, the video streaming selects a keyframe in a lens through cut detection, motion features of the lens and the visual features in the keyframe are extracted and then are stored in a video database, the video retrieval is carried out according to the query submitted by a user and certain features, the retrieved result is fed back to the user according to the similarity degree, and the search result can be optimized when the user is not satisfied with the search result. The dynamic video analysis moving target retrieval system can better integrate the videos and the network, and further effectively solves the problems of storage, playing and transmission of the videos.
