Abstract

La présente invention se rapporte au domaine du codage, du décodage et de la compression vidéo. Les modes de réalisation de la présente invention concernent des procédés et des dispositifs de codage et de décodage, destinés à être utilisés pour résoudre le problème dans un mode de division existant d'une incapacité à satisfaire des exigences de texture relativement complexes. Plus précisément, le procédé de décodage comprend : l'analyse d'un flux de code et la détermination d'un mode de division de base d'un bloc d'image en cours à décoder et d'un mode dérivé cible d'un sous-bloc d'image dans le bloc d'image en cours à décoder ; la division du bloc d'image en cours à décoder en N sous-blocs d'image en fonction du mode dérivé cible, N étant un nombre entier supérieur ou égal à 2 ; la dérivation d'au moins deux sous-blocs d'image adjacents dans les N sous-blocs d'image en un bloc d'image dérivé en fonction du mode dérivé cible ; et le décodage du bloc d'image dérivé.
