Title (EN) METHODS AND APPARATUS FOR PICTURE ENCODING AND DECODING
(FR) PROCÉDÉ ET APPAREIL DE CODAGE ET DE DÉCODAGE D'IMAGE
Abstract:
(EN) A decoding method is disclosed that comprises : - determining whether a current block of a picture extends beyond a boundary of the picture; - determining for each split mode of a plurality of split modes whether said current block is allowed to undergo splitting according to said split mode by checking whether at least one of the split line is co-located with one of the picture border or whether the size of the block part inside the picture along the picture boundary is a multiple of a minimum block size; - decoding from a bitstream a current split mode of the current block responsive to the allowed split modes; and - decoding the current block according to the current split mode.
(FR) L'invention concerne un procédé de décodage comprenant : détermination si un bloc actuel d'une image s'étend au-delà d'une limite de l'image ou non; détermination, pour chaque mode de division d'une pluralité de modes de division, si ledit bloc actuel est autorisé ou non à subir une division conformément audit mode de division en vérifiant si au moins l'une des lignes de division est située au même endroit que l'une des limites d'image ou non ou si la taille de la partie de bloc à l'intérieur de l'image le long de la limite d'image est un multiple d'une taille de bloc minimale ou non; décodage, à partir d'un train de bits, d'un mode de division actuel du bloc actuel en réponse aux modes de division autorisés; et décodage du bloc actuel conformément au mode de division actuel.
