Abstract
(EN) The present invention relates to a video decoding apparatus and method for decoding a multi-view video, and the method for decoding a video, according to the present invention, is the video decoding method for decoding a multi-view video, comprising the steps of: inducing video information required for decoding a current block by entropy-decoding a bitstream; inducing a first disparity vector based on a neighboring block of the current block in the same view by using the video information, inducing a second disparity vector by using the first disparity vector and a reference view depth, and inducing a third disparity vector using the difference between the first disparity vector and the second disparity vector; inducing a prediction sample of the current block by using one of the first disparity vector, the second disparity vector, or the third disparity vector; and applying filtering to a current picture which has been restored using the prediction sample.
(FR) La présente invention concerne un appareil et un procédé de décodage vidéo pour décoder une vidéo multivue, et le procédé pour décoder une vidéo, selon la présente invention, est le procédé de décodage vidéo pour décoder une vidéo multivue comprenant les étapes consistant à : induire des informations vidéo requises pour décoder un bloc actuel en décodant par entropie un train de bits ; induire un premier vecteur de disparité sur la base d'un bloc voisin du bloc actuel dans la même vue en utilisant les informations vidéo, induire un deuxième vecteur de disparité en utilisant le premier vecteur de disparité et une profondeur de vue de référence, et induire un troisième vecteur de disparité utilisant la différence entre le premier vecteur de disparité et le deuxième vecteur de disparité ; induire un échantillon de prédiction du bloc actuel en utilisant l'un du premier vecteur de disparité, du deuxième vecteur de disparité ou du troisième vecteur de disparité ; et appliquer un filtrage à une image actuelle qui a été restaurée en utilisant l'échantillon de prédiction.
