Abstract:
(EN) A method for encoding/decoding an image and a device therefor are disclosed. Specifically, the method for decoding an image comprises the steps of: deriving a motion vector predictor (MVP) and a reference index of a current block; deriving a motion vector (MV) of the current block by using a motion vector difference (MVD) of the current block and the derived MVP; and generating predicted samples of the current block from samples, which are specified by the MV, in a reference picture selected by means of the reference index, wherein the MVP of the current block can be determined as an MV of a motion information candidate block, which is specified by a motion information candidate index of the current block, in a motion information candidate list, and the reference index of the current block can be determined as a reference index of the motion information candidate block.
(FR) L'invention concerne un procédé d'encodage/décodage d'une image et un dispositif correspondant. Plus spécifiquement, le procédé de décodage d’une image comprend les étapes consistant à : obtenir un prédicteur de vecteur de mouvement (MVP) et un indice de référence d'un bloc actuel ; dériver un vecteur de mouvement (MV) du bloc actuel au moyen d'une différence de vecteur de mouvement (MVD) du bloc actuel et du MVP dérivé ; et générer des échantillons prédits du bloc actuel à partir d'échantillons qui sont spécifiés par le MV dans une image de référence sélectionnée au moyen de l'indice de référence, le MVP du bloc actuel pouvant être déterminé en tant qu’un MV d’un bloc candidat d'informations de mouvement spécifié par un indice de candidat d'informations de mouvement du bloc actuel dans une liste de candidats d'informations de mouvement, et l'indice de référence du bloc actuel pouvant être déterminé en tant qu'un indice de référence du bloc candidat d'informations de mouvement.
(KO) 본 발명에서는 영상의 부호화/복호화 방법 및 이를 위한 장치가 개시된다. 구체적으로, 영상을 복호화하는 방법에 있어서, 현재 블록의 움직임 벡터 예측자(MVP: Motion Vector Predictor) 및 참조 인덱스를 도출하는 단계, 상기 현재 블록의 움직임 벡터 차분값(MVD: Motion Vector Difference)과 상기 도출된 MVP를 이용하여 상기 현재 블록의 움직임 벡터(MV: Motion)를 도출하는 단계 및 상기 참조 인덱스에 의해 선택된 참조 픽쳐 내 상기 움직임 벡터에 의해 특정된 샘플들로부터 상기 현재 블록의 예측된 샘플들을 생성하는 단계를 포함하고, 상기 현재 블록의 MVP는 움직임 정보 후보 리스트 내 상기 현재 블록의 움직임 정보 후보 인덱스에 의해 특정되는 움직임 정보 후보 블록의 MV으로 결정되고, 상기 현재 블록의 참조 인덱스는 상기 움직임 정보 후보 블록의 참조 인덱스로 결정될 수 있다.
