Automated analysis of a motion

Abstract

Generating an analysis of a motion is disclosed. A first computing device receives image data that includes a set of user images. Each user image in the set corresponds to a stage of a plurality of consecutive stages of the motion and depicts a user at the corresponding stage. For each stage of the plurality of consecutive stages, a plurality of motion point locations in the corresponding user image is determined. Based on the plurality of motion point locations and reference motion data associated with a reference motion, a user motion report is generated.
