Title (EN) METHOD AND DEVICE FOR VIDEO SIGNAL PROCESSING
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT DE SIGNAL VIDÉO
(KO) 비디오 신호 처리 방법 및 장치
Abstract:
(EN) An image decoding method according to the present invention may comprise: a step of acquiring motion information of a current block; a step of performing motion compensation on the basis of the motion information, thereby acquiring a first prediction block for a first sub block in the current block; and a step of performing overlapped block motion compensation on the first sub block, thereby acquiring a second prediction block.
(FR) L'invention concerne un procédé de décodage d'image qui peut comprendre : une étape d'acquisition d'informations de mouvement d'un bloc courant; une étape de réalisation d'une compensation de mouvement sur la base des informations de mouvement, ce qui permet d'acquérir un premier bloc de prédiction pour un premier sous-bloc dans le bloc courant; et une étape consistant à effectuer une compensation de mouvement de bloc chevauché sur le premier sous-bloc, ce qui permet d'acquérir un second bloc de prédiction.
(KO) 본 발명에 따른 영상 복호화 방법은, 현재 블록에 대한 움직임 정보를 획득하는 단계, 상기 움직임 정보를 기초로 움직임 보상을 수행하여, 상기 현재 블록 내 제1 서브 블록에 대한 제1 예측 블록을 획득하는 단계, 및 상기 제1 서브 블록에 대해 블록 중첩 움직임 보상을 수행하여 제2 예측 블록을 획득하는 단계를 포함할 수 있다.
