Title (EN) INTER PREDICTION MODE BASED IMAGE PROCESSING METHOD AND APPARATUS THEREFOR
(FR) PROCÉDÉ DE TRAITEMENT D'IMAGE FONDÉ SUR UN MODE DE PRÉDICTION INTER ET APPAREIL CORRESPONDANT
(KO) 인터 예측 모드 기반 영상 처리 방법 및 이를 위한 장치
Abstract:
(EN) In the present invention an inter prediction mode based image processing method and an apparatus therefor are disclosed. Specifically, a method of processing an image on the basis of an inter prediction mode may comprise a step of forming a plurality of candidate groups by checking merge candidates according to a predetermined order; a step of extracting a group index indicating a specific candidate group among the plurality of candidate groups; a step of extracting a merge index indicating the specific merge candidate in the candidate group indicated by the group index; and a step of generating a prediction block of a current block using motion information of the merge candidate indicated by the merge index.
(FR) La présente invention concerne un procédé de traitement d'image fondé sur un mode de prédiction inter et un appareil correspondant. Plus particulièrement, un procédé de traitement d'une image fondé sur un mode de prédiction inter peut comprendre la formation d'une pluralité de groupes candidats par la vérification de candidats de fusion selon un ordre prédéterminé; l'extraction d'un indice de groupe indiquant un groupe candidat spécifique parmi la pluralité de groupes candidats; l'extraction d'un indice de fusion indiquant le candidat de fusion spécifique dans le groupe candidat indiqué par l'indice de groupe; et la génération d'un bloc de prédiction d'un bloc en cours à l'aide d'informations de mouvement du candidat de fusion indiqué par l'indice de fusion.
(KO) 본 발명에서는 인터 예측 모드 기반 영상 처리 방법 및 이를 위한 장치가 개시된다. 구체적으로, 인터 예측(inter prediction) 모드 기반으로 영상을 처리하는 방법에 있어서, 미리 정해진 순서에 따라 머지 후보들을 체크하여 복수의 후보 그룹들을 구성하는 단계; 상기 복수의 후보 그룹들 중 특정 후보 그룹을 지시하는 그룹 인덱스를 추출하는 단계; 상기 그룹 인덱스에 의해 지시되는 후보 그룹 내에서 특정 머지 후보를 지시하는 머지 인덱스를 추출하는 단계; 및 상기 머지 인덱스에 의해 지시되는 머지 후보의 움직임 정보를 이용하여 현재 블록의 예측 블록을 생성하는 단계를 포함할 수 있다.
