Abstract

Un procédé d'analyse d'un ensemble d'images d'une séquence vidéo en vue d'un traitement à effectuer sur la séquence est proposé. Le procédé comprend : déterminer dans la séquence vidéo une pluralité de sous-séquences consécutives disjointes d'une ou plusieurs images successives en fonction du type de traitement à effectuer et en fonction du contenu de la séquence vidéo, et analyser les images de chaque sous-séquence déterminée dans la séquence vidéo.
