Abstract:
(EN) Disclosed, in the present invention, are an intra-prediction mode-based image processing method and an apparatus therefor. Specifically, the intra-prediction mode-based image processing method may comprise the steps of: generating a bottom right reference sample adjacent to the bottom right side of a current block; generating a right reference sample of the current block by linearly interpolating a top right reference sample and the bottom right reference sample of the current block, and generating a bottom reference sample of the current block by linearly interpolating a bottom left reference sample and the bottom right reference sample of the current block; and generating a prediction sample of the current block by using a left reference sample, a top reference sample, a right reference sample, and a bottom reference sample of the current block.
(FR) L'invention concerne un procédé de traitement d'image basé sur un mode d'intra-prédiction, et un appareil associé. De façon spécifique, le procédé de traitement d'image basé sur un mode d’intra-prédiction peut comprendre les étapes consistant à : générer un échantillon de référence droit inférieur adjacent au côté droit inférieur d'un bloc actuel ; générer un échantillon de référence droit du bloc actuel via l’interpolation linéaire d'un échantillon de référence droit supérieur et de l'échantillon de référence droit inférieur du bloc actuel, et générer un échantillon de référence inférieur du bloc actuel via l’interpolation linéaire d'un échantillon de référence gauche inférieur et de l'échantillon de référence droit inférieur du bloc actuel ; et générer un échantillon de prédiction du bloc actuel à l'aide d'un échantillon de référence gauche, d'un échantillon de référence supérieur, d'un échantillon de référence droit, et d'un échantillon de référence inférieur du bloc actuel.
(KO) 본 발명에서는 인트라 예측 모드 기반 영상 처리 방법 및 이를 위한 장치가 개시된다. 구체적으로, 인트라 예측(intra prediction) 모드 기반으로 영상을 처리하는 방법에 있어서, 현재 블록의 우하측에 인접한 우하단 참조 샘플을 생성하는 단계; 상기 현재 블록의 우상측 참조 샘플 및 상기 우하단 참조 샘플을 선형 보간하여 상기 현재 블록의 우측 참조 샘플을 생성하고, 상기 현재 블록의 좌하측 참조 샘플 및 상기 우하단 참조 샘플을 선형 보간하여 상기 현재 블록의 하측 참조 샘플을 생성하는 단계; 및 상기 현재 블록의 좌측 참조 샘플, 상측 참조 샘플, 우측 참조 샘플 및 하측 참조 샘플을 이용하여 상기 현재 블록의 예측 샘플을 생성하는 단계를 포함할 수 있다.
