Title
(EN) TRANSFORMATION SELECTION BY TRANSMITTING A TRANSFORMATION SET INDICATOR FOR USE IN VIDEO CODING
(FR) SÉLECTION DE TRANSFORMATION PAR TRANSMISSION D'UN INDICATEUR D'ENSEMBLE DE TRANSFORMATION DESTINÉ À ÊTRE UTILISÉ EN CODAGE VIDÉO
Abstract
(EN)
A method (200) for encoding a picture (120b) is provided. The method comprises generating (22) and transmitting (24) a transformation indicator (110, 940) indicating a transformation for one or more samples (130) of the picture (120b). The transformation is used to encode (26) the picture (120b). A method for decoding an encoded picture is provided. The method comprises receiving (32) a transformation indicator (110, 940) indicating a transformation for one or more samples (130) of the encoded picture. The method comprises receiving (34) a bitstream comprising the encoded picture. The method comprises decoding (36) the encoded picture in accordance with the received transformation indicator.

L'invention concerne un procédé (200) de codage d'une image (120b). Le procédé consiste à générer (22) et à transmettre (24) un indicateur de transformation (110, 940) indiquant une transformation pour un ou plusieurs échantillons (130) de l'image (120b). La transformation est utilisée pour coder (26) l'image (120b). L'invention concerne également un procédé de décodage d'une image codée. Le procédé consiste à recevoir (32) un indicateur de transformation (110, 940) indiquant une transformation pour un ou plusieurs échantillons (130) de l'image codée. Le procédé consiste à recevoir (34) un train de bits comprenant l'image codée. Le procédé consiste à décoder (36) l'image codée conformément à l'indicateur de transformation reçu.
