Abstract: front page image
(EN)A method for intra prediction according to the present invention comprises the steps of: determining a first MPM candidate corresponding to a left-side candidate block on the basis of a position of the left-side candidate block adjacent to a left side of a current block; determining a second MPM candidate corresponding to an upper-end candidate block on the basis of a position of the upper-end candidate block adjacent to an upper end of the current block; generating an MPM candidate list including a plurality of MPM candidates, on the basis of the first MPM candidate and the second MPM candidate; and determining one MPM candidate of the plurality of the MPM candidates that constitute the MPM candidate list as an intra prediction mode of the current block, and performing intra prediction for the current block on the basis of the determined intra prediction mode to generate a prediction block corresponding to the current block.
(FR)La présente invention concerne un procédé de prédiction intra qui comprend les étapes consistant à : déterminer un premier candidat MPM correspondant à un bloc de candidat côté gauche sur la base d'une position du bloc de candidat côté gauche adjacent à un côté gauche d'un bloc courant ; déterminer un second candidat MPM correspondant à un bloc de candidat d'extrémité supérieure sur la base d'une position du bloc de candidat d'extrémité supérieure adjacent à une extrémité supérieure du bloc courant ; générer une liste de candidats MPM comprenant une pluralité de candidats MPM, sur la base du premier candidat MPM et du second candidat MPM ; et déterminer un candidat MPM parmi la pluralité de candidats MPM qui constituent la liste de candidats MPM en tant que mode de prédiction intra du bloc courant, et réaliser une prédiction intra pour le bloc courant sur la base du mode de prédiction intra déterminé pour générer un bloc de prédiction correspondant au bloc courant.
(KO)본 발명에 따른 인트라 예측 방법은, 현재 블록의 좌측에 인접한 좌측 후보 블록의 위치를 기반으로 좌측 후보 블록에 대응하는 제1 MPM 후보를 결정하는 단계, 현재 블록의 상단에 인접한 상단 후보 블록의 위치를 기반으로 상단 후보 블록에 대응하는 제2 MPM 후보를 결정하는 단계, 제1 MPM 후보 및 제2 MPM 후보를 기반으로, 복수의 MPM 후보를 포함하는 MPM 후보 리스트를 생성하는 단계; 및 MPM 후보 리스트를 구성하는 복수의 MPM 후보 중에서 하나의 MPM 후보를 현재 블록의 인트라 예측 모드로 결정하고, 결정된 인트라 예측 모드를 기반으로 현재 블록에 대해 인트라 예측을 수행함으로써, 현재 블록에 대응하는 예측 블록을 생성하는 단계를 포함한다.
