Abstract:
(EN) A method for decoding an image according to an embodiment of the present invention is an image decoding method comprising: a step of determining a coding unit of a decoding target block; a step of determining a prediction mode corresponding to the coding unit; a step of performing prediction processing corresponding to the prediction mode; a step of determining a scanning order corresponding to a transformation coefficient group, according to the prediction processing; a step of determining a transformation coefficient based on the scanning order corresponding to the transformation coefficient group; a step of performing inverse transformation processing using the determined transformation coefficient; a step of performing inverse quantization processing corresponding to the inverse transformation processing; and a step of processing in-loop filtering of the target block which has been subjected to the inverse quantization processing.
(FR) Un mode de réalisation de la présente invention concerne un procédé de décodage d'image utilisé pour décoder une image. Le procédé comprend les étapes consistant à : déterminer une unité de codage d'un bloc cible de décodage ; déterminer un mode de prédiction correspondant à l'unité de codage ; exécuter une opération de prédiction correspondant au mode de prédiction ; déterminer un ordre de balayage correspondant à un groupe de coefficients de transformée, d’après l’opération de prédiction ; déterminer un coefficient de transformée sur la base de l'ordre de balayage correspondant au groupe de coefficients de transformée ; exécuter une opération de transformée inverse à l'aide du coefficient de transformée déterminé ; exécuter une opération de quantification inverse correspondant à l’opération de transformée inverse ; et exécuter un filtrage en boucle du bloc cible ayant subi l’opération de quantification inverse.
