Abstract

L'invention concerne un procédé d'inter-prédiction comprenant: une étape consistant à dériver des informations de mouvement de référence concernant une unité à décoder dans une image courante; et une étape consistant à effectuer une compensation de mouvement de l'unité à décoder en utilisant les informations de mouvement de référence qui ont été dérivées. La présente invention permet d'améliorer l'efficacité de codage/décodage d'image.
