Abstract
(EN)
Provided are an image encoding/decoding method and apparatus. The image decoding method according to the present invention may comprise the steps of: configuring a motion information list for a current block; restoring a first index for a triangular block in the current block and a second index for a second triangular block in the current block; and predicting, on the basis of the first index, the second index and the motion information list, the first triangular block and the second triangular block.
(FR)
L'invention concerne un procédé et un appareil d'encodage/de décodage d'image. Le procédé de décodage d'image selon la présente invention peut comprendre les étapes suivantes : configurer une liste d'informations de mouvement pour un bloc actuel ; restaurer un premier indice pour un bloc triangulaire dans le bloc actuel et un deuxième indice pour un deuxième bloc triangulaire dans le bloc actuel ; et prédire, en fonction du premier indice, du deuxième indice et de la liste d'informations de mouvement, le premier bloc triangulaire et le deuxième bloc triangulaire.
