Title (EN) INTER PREDICTION MODE-BASED IMAGE PROCESSING METHOD AND APPARATUS THEREFOR
(FR) PROCÉDÉ DE TRAITEMENT D'IMAGE BASÉ SUR UN MODE DE PRÉDICTION INTER ET APPAREIL ASSOCIÉ
(KO) 인터 예측 모드 기반 영상 처리 방법 및 이를 위한 장치
Abstract: front page image
(EN) An inter prediction mode-based image processing method and an apparatus therefor are disclosed. Particularly, a method for processing an image on the basis of an inter prediction comprises the steps of: deriving reverse motion information of a current block by using motion information of a block within a reference picture of a current picture; adding the reverse motion information as a motion information candidate, to a motion information candidate list, of the current block, comprising a plurality of motion information candidates; deriving the motion information of the current block from the motion information selected among the plurality of motion information candidates within the motion information candidate list; and generating a prediction block of the current block by using the motion information of the current block, wherein the block within the reference picture can be specified by the reverse motion information.
(FR) La présente invention concerne un procédé de traitement d'image basé sur un mode de prédiction inter et un appareil associé. Plus précisément, un procédé de traitement d'une image sur la base d'une prédiction inter comprend les étapes consistant à : déduire des informations de mouvement inverse d'un bloc actuel à l'aide d'informations de mouvement d'un bloc dans une image de référence d'une image actuelle ; ajouter les informations de mouvement inverse, à titre d'informations de mouvement candidates, à une liste d'informations de mouvement candidates du bloc actuel contenant une pluralité d'informations de mouvement candidates ; déduire les informations de mouvement du bloc actuel à partir des informations de mouvement sélectionnées parmi la pluralité d'informations de mouvement candidates dans la liste d'informations de mouvement candidates ; et générer un bloc de prédiction du bloc actuel à l'aide des informations de mouvement du bloc actuel, le bloc dans l'image de référence pouvant être spécifié par les informations de mouvement inverse.
(KO) 본 발명에서는 인터 예측 모드 기반 영상 처리 방법 및 이를 위한 장치가 개시된다. 구체적으로, 인터 예측(inter prediction)을 기반으로 영상을 처리하는 방법에 있어서, 현재 픽쳐(current picture)의 참조 픽쳐(reference picture) 내 블록의 움직임 정보를 이용하여, 현재 블록(current block)의 역방향 움직임 정보를 도출하는 단계, 복수의 움직임 정보 후보로 구성되는 상기 현재 블록의 움직임 정보 후보 리스트에 상기 역방향 움직임 정보를 움직임 정보 후보로서 추가하는 단계, 상기 움직임 정보 후보 리스트 내 상기 복수의 움직임 정보 후보 중에서 선택된 움직임 정보로부터 상기 현재 블록의 움직임 정보를 도출하는 단계 및 상기 현재 블록의 움직임 정보를 이용하여 상기 현재 블록의 예측 블록을 생성하는 단계를 포함하고, 상기 역방향 움직임 정보에 의해 상기 참조 픽쳐 내 블록이 특정될 수 있다.
