SYSTEMS AND METHODS FOR ANALYZING A MOTION BASED ON IMAGES

A method for determining posture-related information of a subject using the subject's image is provided. The method comprises: determining, from a first image, first positions of a first pair of joints and a first body segment length of a first body segment associated with the first pair of joints; determining, from a second image, second positions of a second pair of joints and a second body segment length of a second body segment associated with the second pair of joints; determining, based on an algorithm that reduces a difference between the first and second body segment lengths, whether the first and second pairs of joints correspond to a pair of joints; if the first and second pairs of joints are determined to correspond to a pair of joints, determining, based on the second positions, information of a posture of the subject; and providing an indication regarding the information.
