Abstract:
(EN) The present invention relates to an image encoding/decoding method and device. An image decoding method according to the present invention may comprise the steps of: configuring an MPM list on the basis of intra-picture prediction modes of adjacent blocks of a current block and frequencies of the intra-picture prediction modes of the adjacent blocks; inducing an intra-picture prediction mode of the current block on the basis of the MPM list; and performing intra-picture prediction for the current block on the basis of the intra-picture prediction mode.
(FR) La présente invention concerne un procédé et un dispositif d'encodage/de décodage d'une image. Un procédé de décodage d'image selon la présente invention peut comprendre les étapes suivantes : configurer une liste de MPM en fonction de modes de prédiction intra-image de blocs adjacents d'un bloc actuel et de fréquences des modes de prédiction intra-image des blocs adjacents ; induire un mode de prédiction intra-image du bloc actuel en fonction de la liste de MPM ; et réaliser une prédiction intra-image pour le bloc actuel en fonction du mode de prédiction intra-image.
(KO) 본 발명은 영상 부호화/복호화 방법 및 장치에 관한 것이다. 본 발명에 따른 영상 복호화 방법은 현재 블록의 인접 블록들의 화면 내 예측 모드들 및 상기 인접 블록들의 화면 내 예측 모드들의 빈도수에 기초하여 MPM 리스트를 구성하는 단계, 상기 MPM 리스트에 기초하여 상기 현재 블록의 화면 내 예측 모드를 유도하는 단계, 및 상기 화면 내 예측 모드에 기초하여 상기 현재 블록에 대한 화면 내 예측을 수행하는 단계를 포함할 수 있다.
