Abstract: front page image
(EN)Disclosed are an intra-prediction mode-based image processing method and an apparatus therefor. Particularly, the intra-prediction mode-based image processing method may comprise the steps of: generating a predicted sample of a current block on the basis of an intra-prediction mode of the current block; calculating the distance between the predicted sample and a first reference sample used to generate the predicted sample; and when the distance between the predicted sample and the first reference sample is larger than a filtering reference value, filtering the predicted sample by a weighted addition of the predicted sample and a second reference sample, wherein, among reference samples adjacent to the current block, at least one of a reference sample having the same horizontal coordinate component as the predicted sample and a reference sample having the same vertical coordinate component as the predicted sample is used as the second reference sample.
(FR)L'invention concerne un procédé de traitement d'image basé sur un mode d'intraprédiction, et un appareil associé. En particulier, le procédé de traitement d'image basé sur un mode d'intraprédiction peut comprendre les étapes consistant à : générer un échantillon prédit d'un bloc actuel sur la base d'un mode d'intraprédiction du bloc actuel ; calculer la distance entre l'échantillon prédit et un premier échantillon de référence utilisé pour générer l'échantillon prédit ; et lorsque la distance entre l'échantillon prédit et le premier échantillon de référence est supérieure à une valeur de référence de filtrage, filtrer l'échantillon prédit par addition pondérée de l'échantillon prédit et d'un second échantillon de référence, où parmi des échantillons de référence adjacents au bloc actuel, au moins un échantillon de référence ayant le même composant de coordonnées horizontales que l'échantillon prédit et/ou un échantillon de référence ayant le même composant de coordonnées verticales que l'échantillon prédit est utilisé en tant que second échantillon de référence.
(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 인트라 예측 모드에 기반하여 상기 현재 블록의 예측 샘플(predicted sample)을 생성하는 단계; 상기 예측 샘플과 상기 예측 샘플의 생성에 이용된 제 1 참조 샘플간의 거리를 계산하는 단계; 및 상기 예측 샘플과 상기 제 1 참조 샘플간의 거리가 필터링 기준 값보다 큰 경우, 상기 현재 블록에 이웃하는 참조 샘플 중에서, 상기 예측 샘플과 수직 좌표가 동일한 샘플 및 상기 예측 샘플과 수평 좌표가 동일한 샘플 중 적어도 어느 하나를 제 2 참조 샘플로서 상기 예측 샘플과 가중합함으로써 상기 예측 샘플에 필터링을 수행하는 단계를 포함할 수 있다.
