In order to improve the deficiency of comparability measure between the frames in the recent method of key-frame extracting,a new method of key-frame extracting based on color layout feature and block-moving information of MPEG-7 is proposed in this paper.This paper gives the method of extracting the color layout feature and matching them,and gives the method of computing the block-moving information by using image segmentation scheme,and then,it extracts the key-frames by combing the cumulative distance of detection methods.The experiment results show that our method is more accurate than the method,which uses the integrated feature of image to extract the key-frames,and doesn't easy to have redundancy and undetected,and the extracted key-frames make a good representation for video contents.
