Abstract[English]
The invention relates to a method and device for encoding and decoding images comprising a plurality of samples to be encoded or decoded. The decoding method comprises the following steps: - decoding (E31) a group of feature maps (FMdi) representative of the current image, the group comprising at least one feature map having a lower resolution than the resolution of the input image, which map is referred to as a lower resolution map; - obtaining (E33) a set of parameters (WUck) representative of at least one neural network (UP1) referred to as an oversampling neural network; - oversampling (E34) the at least one lower resolution feature map using the oversampling network to obtain an oversampled map at the resolution of the at least one image; - generating (E35) the at least one image from the at least one oversampled map.[French]
L'invention concerne un procédé et dispositif de codage et décodage d'images comprenant une pluralité d'échantillons à coder ou décoder. Le procédé de décodage comporte les étapes suivantes : - décodage (E31) d'un groupe de cartes de caractéristiques (FMdi) représentatives de l'image courante, ledit groupe comprenant au moins une carte de caractéristiques de résolution inférieure à la résolution de l'image d'entrée, dite carte de résolution inférieure; - obtention (E33) d'un ensemble de paramètres (WUck) représentatifs d'un réseau de neurones (UP1) au moins, dit réseau de neurones de suréchantillonnage; - suréchantillonnage (E34) de ladite au moins une carte de caractéristiques de résolution inférieure en utilisant ledit réseau de suréchantillonnage pour obtenir une carte suréchantillonnée à la résolution de ladite au moins une image; - génération (E35) de ladite au moins une image à partir de ladite au moins une carte suréchantillonnée.
