Abstract

Le procédé est caractérisé en ce qu'il effectue les étapes suivantes: détermination (8) du type de fenêtre de prédiction (15) liée au vecteur mouvement, non sortante ou sortante selon que la fenêtre de prédiction (15) est positionnée entièrement ou en partie dans l'image de référence (14), si la fenêtre de prédiction est de type sortante, remplissage d'une zone tampon de prédiction de dimensions au moins égales à celles de la fenêtre de prédiction et positionnée, pour définir ce remplissage, de manière à inclure la fenêtre de prédiction, par les pixels de l'image de référence (10) communs à la zone de prédiction (18) et, pour la partie restante (19, 20, 21), par recopie (11), parmi ces pixels, de ceux en bordure de l'image, calcul du prédicteur à partir des pixels (11) de la zone tampon se trouvant dans la fenêtre de prédiction (15). Les applications concernent la compression au format H 264 ou MPEG 4 part 10.
