Abstract

L'invention concerne un procédé d'obtention d'un vecteur de disparité adaptatif dans un HEVC en 3D. Dans un procédé d'obtention d'un vecteur de disparité adaptatif, trois candidats DV sont obtenus à partir de blocs voisins. Le codeur peut trouver le meilleur candidat DV utilisé pour réaliser une prédiction résiduelle perfectionnée (ARP) et pour signaler l'indice du candidat DV sélectionné au décodeur.
