Abstract
(EN) Disclosed in the present invention is a picture processing method and an apparatus for same. Particularly, a picture decoding method may comprise the steps of: generating a prediction block for a current processing block using the prediction mode of the current processing block, wherein the current processing block is a leaf node block of a quadtree resulting from dividing a basic picture division unit according to a quadtree structure, which is further divided according to a binary tree structure; determining whether a skip mode applies to the current processing block; and generating a residual block of the current processing block when the skip mode does not apply to the current processing block.
(FR) La présente invention concerne un procédé de traitement d'image et un appareil associé. En particulier, un procédé de décodage d'image peut comprendre les étapes suivantes : la génération d'un bloc de prédiction pour un bloc de traitement actuel à l'aide du mode de prédiction du bloc de traitement actuel, le bloc de traitement actuel étant un bloc de nœud feuille d'un arbre quaternaire qui résulte de la division d'une unité de division d'image de base selon une structure d'arbre quaternaire, qui est en outre divisée selon une structure d'arbre binaire ; la détermination qu'un mode de saut s'applique ou non au bloc de traitement actuel ; et la génération d'un bloc résiduel du bloc de traitement actuel lorsque le mode de saut n'est pas appliqué au bloc de traitement actuel.
(KO) 본 발명에서는 영상 처리 방법 및 이를 위한 장치가 개시된다. 구체적으로, 영상을 복호화하는 방법에 있어서, 현재 처리 블록의 예측 모드를 이용하여 상기 현재 처리 블록의 예측 블록(prediction block)을 생성하는 단계, 여기서, 상기 현재 처리 블록은 영상(picture)을 분할하는 기본 단위로부터 쿼드 트리 구조(quad tree structure)로 분할된 쿼드 트리의 리프 노드(leaf node) 블록이 바이너리 트리 구조(binary tree structure)로 분할된 블록을 나타냄; 상기 현재 처리 블록에 대하여 스킵(skip) 모드가 적용되는지 여부를 판단하는 단계; 및 상기 현재 처리 블록에 대하여 상기 스킵 모드가 적용되지 않는 경우, 상기 현재 처리 블록의 잔차 블록(residual block)을 생성하는 단계를 포함할 수 있다.
