Abstract
(EN)
A method and an apparatus for image encoding/decoding, according to the present invention, may generate a candidate list of a current block and perform inter-prediction of the current block by using any one of a plurality of candidates belonging to the candidate list. Here, the plurality of candidates comprise at least one from among a spatial candidate, a temporal candidate, and a restoration information-based candidate, and the restoration information-based candidate may be added from a buffer which stores motion information decoded prior to the current block.
(FR)
La présente invention porte sur un procédé et un appareil de codage/décodage d'image, qui peuvent générer une liste de candidats d'un bloc courant et effectuer une prédiction inter du bloc courant à l'aide d'un candidat quelconque d'une pluralité de candidats appartenant à la liste de candidats. Ici, la pluralité de candidats comprennent au moins un candidat parmi un candidat spatial, un candidat temporel et un candidat basé sur des informations de restauration, et le candidat basé sur des informations de restauration peut être ajouté à partir d'un tampon qui stocke des informations de mouvement décodées avant le bloc courant.
