Abstract

Il est proposé un procédé de traitement d’au moins une zone d’image décodée, le procédé comportant : - en sortie d’une boucle de décodage ayant décodé au moins une zone d’image courante, un traitement de la zone d’image courante décodée, à l’aide d’un module de lissage de frontière utilisant des métadonnées relatives au moins à une frontière entre la zone d’image courante et une zone d’image voisine.
