摘      要：In this paper we introduce a video post-processing method that enhances the rhythm of a dancing performance,in the sense that the dancing movements are more in time to the beat of the *** dancing performance as observed in a video is analyzed and segmented into motion intervals delimited by motion *** present an image-space method to extract the motion beats of a video by detecting frames at which there is a significant change in direction or motion *** motion beats are then synchronized with the music beats such that as many beats as possible are matched with as little as possible time-warping distortion to the *** show two applications for this cross-media synchronization:one where a given dance performance is enhanced to be better synchronized with its original music,and one where a given dance video is automatically adapted to be synchronized with different music.
