Abstract:
(EN) Provided are a method and a device for, during video encoding and decoding, determining whether or not local luminance compensation is to be applied on the basis of information relating to whether or not local luminance compensation is applied to neighboring blocks adjacent to a current block, determining a local luminance compensation model if the local luminance compensation has been determined to be applied, and applying the local luminance compensation to the current block by means of the determined luminance compensation model.
(FR) L'invention concerne un procédé et un dispositif pour, pendant un codage et un décodage vidéo, déterminer si une compensation de luminance locale doit être appliquée sur la base d'informations relatives à la question de savoir si une compensation de luminance locale est appliquée ou non à des blocs voisins adjacents à un bloc actuel, déterminer un modèle de compensation de luminance locale si la compensation de luminance locale a été déterminée comme étant appliquée, et appliquer la compensation de luminance locale au bloc actuel au moyen du modèle de compensation de luminance déterminé.
(KO) 비디오 부호화 및 복호화 과정 중에서, 현재 블록에 이웃하는 주변 블록의 로컬 휘도 보상 적용 여부에 대한 정보에 기초하여 로컬 휘도 보상 적용 여부를 결정하고, 로컬 휘도 보상을 적용하도록 결정된 경우, 로컬 휘도 보상 모델을 결정하고, 결정된 휘도 보상 모델을 이용하여 현재 블록에 로컬 휘도 보상을 적용하는 방법 및 장치를 제안한다.
