Abstract
(EN) Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and a method for performing operations comprising: receiving a video that includes a depiction of a body of a user; detecting a plurality of skeletal joints of the body depicted in the video; tracking movement of the plurality of skeletal joints across a set of frames of the video; and smoothing the movement of a first set of the plurality of skeletal joints between frames in the first set of frames independently of smoothing movement of a second set of the plurality of skeletal joints in the first set of frames.
(FR) Des aspects de la présente divulgation concernent un système comprenant un support de stockage lisible par ordinateur stockant un programme et un procédé permettant d'effectuer des opérations consistant : à recevoir une vidéo qui comprend la description du corps d'un utilisateur; à détecter une pluralité d'articulations squelettiques du corps représenté dans la vidéo; à suivre le mouvement de la pluralité d'articulations squelettiques sur un ensemble de trames de la vidéo; et à lisser le mouvement d'un premier ensemble de la pluralité d'articulations squelettiques entre des trames dans le premier ensemble de trames indépendamment du mouvement de lissage d'un second ensemble de la pluralité d'articulations squelettiques dans le premier ensemble de trames.
