Along with widely using of H.264/AVC,the scene change detection in H.264/AVC compressed domain becomes a hot issue in Context-Based Video Retrieval field.Base on the character that there is less temporal correlation between frames where scene change oc-curs,according to different macro-block prediction mode in the whole frame,the proposed algorithms obtain candidates of scene change frames.To find accurate scene changes,we use the part characteristic of the fame.The experimental results shows that the propo...
