Abstract
(EN)
The present invention relates to a method for performing motion compensation by using motion vector prediction. To this end, an image decoding method may comprise the steps of: generating a list of multiple motion vector candidates according to an inter-prediction direction of a current block; deriving multiple motion vectors for the current block, using the list of the multiple motion vector candidates; determining multiple prediction blocks for the current block, using the multiple motion vectors; and acquiring a final prediction block for the current block on the basis of the multiple prediction blocks.

La présente invention concerne un procédé pour effectuer une compensation de mouvement à l'aide d'une prédiction de vecteur de mouvement. À cet effet, un procédé de décodage d'images peut comprendre : la génération d'une liste de vecteurs de mouvement candidats multiples selon une direction d'inter-prédiction d'un bloc en cours ; la déduction de vecteurs de mouvement multiples pour le bloc en cours, à l'aide de la liste des vecteurs de mouvement candidats multiples ; la détermination de blocs de prédiction multiples pour le bloc en cours, à l'aide des vecteurs de mouvement multiples ; et l'acquisition d'un bloc de prédiction final pour le bloc en cours en fonction des blocs de prédiction multiples.
