    摘要： A video is summarized by determining if a video contains one or more junk frames, modifying one or more boundaries of shots of the video based at least in part on the determination of if the video contains one or more junk frames, sampling a plurality of the shots of the video into a plurality of subshots, clustering the plurality of subshots with a multiple step k-means clustering, and creating a video summary based at least in part on the clustered plurality of subshots. The video is segmented into a plurality of shots and a keyframe from each of the plurality of shots is extracted. A video summary is created based on a determined importance of the subshots in a clustered plurality of subshots and a time budget. The created video summary is rendered by displaying playback rate information for the rendered video summary, displaying a currently playing subshot marker with the rendered video summary, and displaying an indication of similar content in the rendered video summary.
