Abstract[English]
Methods and apparatuses are provided for processing video data by using generative face video supplemental enhancement information (SEI) messages. An exemplary method for generating a face picture includes: receiving a bitstream; decoding coded information of the bitstream to obtain a base picture and a supplemental enhancement information (SEI) message; determining whether the SEI message applies to a neural network for generating a face picture; in response to the SEI message applies to the neural network for generating the face picture, determining a mode and a corresponding face information parameter used to code the face picture based on the SEI message; and generating the face picture based on the base picture and the face information parameter by the neural network.[French]
L'invention concerne des procédés et des appareils de traitement de données vidéo à l'aide de messages d'informations d'amélioration supplémentaire (SEI) vidéo de visage génératif. Un procédé donné à titre d'exemple pour générer une image de visage consiste à : recevoir un train de bits ; décoder des informations codées du train de bits pour obtenir une image de base et un message de SEI ; déterminer si le message de SEI s'applique à un réseau neuronal pour générer une image de visage ; en réponse à l'application du message de SEI au réseau neuronal pour générer l'image de visage, déterminer un mode et un paramètre d'informations de visage correspondant utilisés pour coder l'image de visage sur la base du message de SEI ; et générer l'image de visage sur la base de l'image de base et du paramètre d'informations de visage par le réseau neuronal.
