Abstract
Abstract: Aiming at the complicated and redundant action of music and dance video, a method of extracting dance video key frame is proposed. The optical flow of two adjacent image frames in the dance video is calculated. The entropy of each optical flow graph is calculated and the characteristics of the music in the dance video are extracted. The music characteristics are merged with the entropy sequence of the optical flow graph and a sequence of entropy matching with music is obtained. The key frame of dance video is achieved by threshold comparison. The experimental results show that the algorithm can effectively extract the key frames with less redundancy and summary of the video content, and plays an important role in the analysis of dance video and choreography.
