Abstract:: This paper proposes a new method of the key frame extraction aiming at reducing storage and fastretrieval of the surveillance video.First,an improved background subtraction is used to detect the key videosegment which contains the moving objects,and record the first frame and the last frame of the segment.Thenthe key frames are extracted coarsely in the video segment based on the joint histogram. Finally,according tothe continuity of the key video frames,we further refine the key frames by image information entropy. The ex-perimental results show that the method can extract the key frames of the surveillance video effectively.Itgreatly reduces the storage of the video data,and helps the users to browse key information easily.
