Abstract
This disclosure provides techniques of extracting movements from a dance video. The techniques comprise receiving a dance video that includes one or more dancers and that is uploaded by a user, and obtaining a video frame in the dance video; recognizing, based on a skeleton node recognition algorithm, skeleton node images from the video frames corresponding to a target dancer, where the target dancer is selected from the one or more dancers; performing cluster analysis on the skeleton node images recognized from the dance video and corresponding to each target dancer to obtain a plurality of cluster sets; determining a cluster center in each of the plurality of cluster sets as a key skeleton node image; and sequentially outputting the key skeleton node images to obtain a standard movement sequence corresponding to each target dancer in the dance video.
