Abstract

Procédé d’encodage d’images, et dispositif associé L‘invention concerne un procédé et un dispositif de codage d’un premier ensemble de pixels d’une image ou séquence d’images, dite partition cible (PC). Le procédé comprend, pour ladite au moins une partition cible : - obtenir (S3, S13) un train binaire (TBi) représentatif d’un second ensemble de pixels, dit partition source identifiée (PSi), distinct du premier ensemble; - utiliser (S6, S16) ledit train binaire pour l’encodage de ladite partition cible. Figure pour l’abrégé : Fig. 3.
