Abstract: front page image
(EN)Disclosed are a deblocking method and a deblocking apparatus for a block on which intra prediction is performed. An intra prediction method may comprise: a step of determining an intra prediction mode of a plurality of adjacent blocks to calculate a plurality of candidate intra prediction modes which are prediction values of the intra prediction mode of the current block; a step of determining the intra prediction mode of the current block based on the prediction value of the intra prediction mode of the current block obtained based on the plurality of candidate intra prediction modes; and a step of outputting, as a restored block, the block obtained by filtering the prediction block generated based on the intra prediction mode of the current block by means of a deblocking filter in cases where the current block uses an intra skip mode. Thus, encoding/decoding efficiency may be increased and image encoding/decoding complexity may be reduced.
(FR)L'invention concerne un procédé de déblocage et un appareil de déblocage pour un bloc sur lequel une prédiction intra est exécutée. Selon l'invention, un procédé de prédiction intra peut comprendre : une étape qui consiste à déterminer un mode de prédiction intra d'une pluralité de blocs adjacents pour calculer une pluralité de modes de prédiction intra candidats qui sont des valeurs de prédiction du mode de prédiction intra du bloc courant ; une étape qui consiste à déterminer le mode de prédiction intra du bloc courant sur la base de la valeur de prédiction du mode de prédiction intra du bloc courant obtenu sur la base de la pluralité de modes de prédiction intra candidats ; et une étape qui consiste à produire, en tant que bloc restauré, le bloc obtenu par filtrage du bloc de prédiction généré sur la base du mode de prédiction intra du bloc courant au moyen d'un filtre de déblocage dans les cas où le bloc courant utilise un mode de saut intra. L'efficacité de codage/décodage peut ainsi être augmentée et la complexité de codage/décodage d'image peut être réduite.
(KO)화면 내 예측을 수행한 블록에 대한 디블록킹 방법 및 장치가 개시되어 있다. 화면 내 예측 방법은 복수의 주변 블록의 화면 내 예측 모드를 판단하여 현재 블록의 화면 내 예측 모드의 예측 값인 복수의 후보 화면 내 예측 모드를 산출하는 단계, 복수의 후보 화면 내 예측 모드를 기초로 현재 블록의 화면 내 예측 모드를 예측한 값을 기초로 상기 현재 블록의 화면 내 예측 모드를 결정하는 단계와 현재 블록이 인트라 스킵 모드(intra skip mode)를 사용하는 경우 상기 현재 블록의 화면 내 예측 모드를 기초로 생성된 예측 블록을 디블록킹 필터를 통해 필터링한 블록을 복원 블록으로 출력하는 단계를 포함할 수 있다. 따라서, 부호화/복호화 효율을 증가시키고 영상 부호화/복호화의 복잡도를 감소시킬 수 있다.
