Summary: | An image decoding method is disclosed. An image decoding method according to the present invention may comprise the steps of: deriving initial motion information of the current block from at least one of motion information of a spatial neighboring block, motion information of a temporal neighboring block, and predefined motion information; generating corrected motion information by performing motion-information-correction on the initial motion information; and generating a prediction block of the current block by using the corrected motion information.
La présente invention concerne un procédé de décodage d'image. Conformément à la présente invention, un procédé de décodage d'image peut comprendre les étapes consistant : à déduire des informations de mouvement initiales du bloc actuel à partir d'au moins une des informations de mouvement d'un bloc voisin spatial, des informations de mouvement d'un bloc voisin temporel, et des informations de mouvement prédéfinies ; à générer des informations de mouvement corrigées en réalisant une correction d'informations de mouvement sur les informations de mouvement initiales ; et à générer un bloc de prédiction du bloc actuel à l'aide des informations de mouvement corrigées.
