Title (EN) METHOD FOR ENCODING/DECODING IMAGE AND DEVICE THEREFOR
(FR) PROCÉDÉ POUR CODER/DÉCODER UNE IMAGE ET DISPOSITIF ASSOCIÉ
(KO) 영상의 부호화/복호화 방법 및 이를 위한 장치
Abstract: front page image
(EN) Disclosed are a method for encoding/decoding an image and a device therefor. Particularly, a method by which a decoding device decodes an image comprises the steps of: deriving a partition mode of a coding block within a predefined partition mode set; decoding a motion parameter in a prediction block unit partitioned from the coding block according to the partition mode; and generating a predicted block by using the motion parameter decoded in the prediction block unit, wherein the partition mode set includes an asymmetric 4-block partition mode, the asymmetric 4-block partition mode enables four prediction blocks to be partitioned from the coding block, and a horizontal partition and/or a vertical partition can be defined as an asymmetric partition form.
(FR) L’invention concerne un procédé pour coder/décoder une image et un dispositif associé. En particulier, un procédé au moyen duquel un dispositif de décodage décode une image consiste : à dériver un mode de partition d’un bloc de codage dans un ensemble de modes de partition prédéfini ; à décoder un paramètre de mouvement dans une unité de bloc de prédiction partitionnée à partir du bloc de codage selon le mode de partition ; à générer un bloc prédit par utilisation du paramètre de mouvement décodé dans l’unité de bloc de prédiction ; l’ensemble de modes de partition comprenant un mode de partition de 4 blocs asymétrique, le mode de partition de 4 blocs asymétrique permettant à quatre blocs de prédiction d’être partitionnés à partir du bloc de codage, et une partition horizontale et/ou une partition verticale pouvant être définies comme une forme de partition asymétrique.
(KO) 본 발명에서는 영상의 부호화/복호화 방법 및 이를 위한 장치가 개시된다. 구체적으로, 복호화 장치가 영상을 복호화하는 방법에 있어서, 미리 정의된 분할 모드 세트 내에서 코딩 블록(coding block)의 분할 모드(part mode)를 도출하는 단계, 상기 분할 모드에 따라 상기 코딩 블록으로부터 분할된 예측 블록(prediction block) 단위로 움직임 파라미터를 복호화하는 단계 및 상기 예측 블록 단위로 복호화된 움직임 파라미터를 이용하여 예측된 블록(predicted block)을 생성하는 단계를 포함하고, 상기 분할 모드 세트는 비대칭적 4 블록 분할 모드를 포함하고, 상기 비대칭적 4 블록 분할 모드는 상기 코딩 블록으로부터 4개의 예측 블록이 분할되고, 수평 방향의 분할과 수직 방향의 분할 중 적어도 어느 하나의 분할이 비대칭적인 분할 형태로 정의될 수 있다.
