Title
(EN) METHOD AND APPARATUS FOR MULTI-RATE NEURAL IMAGE COMPRESSION WITH MICRO-STRUCTURED MASKS
(FR) PROCÉDÉ ET APPAREIL DE COMPRESSION D'IMAGE NEURONALE À DÉBITS MULTIPLES AVEC DES MASQUES MICROSTRUCTURÉS
Abstract
(EN) A method of multi-rate neural image compression includes selecting encoding masks, based on a hyperparameter, and performing a convolution of a first plurality of weights of a first neural network and the selected encoding masks to obtain first masked weights. The method further includes encoding an input image to obtain an encoded representation, using the first masked weights, and encoding the obtained encoded representation to obtain a compressed representation.
(FR) La présente invention concerne un procédé de compression d'image neuronale à débits multiples comprenant les étapes consistant à sélectionner des masques de codage, sur la base d'un hyperparamètre, et à effectuer une convolution d'une première pluralité de poids d'un premier réseau neuronal et des masques de codage sélectionnés pour obtenir des premiers poids masqués. Le procédé comprend en outre le codage d'une image d'entrée pour obtenir une représentation codée, à l'aide des premiers poids masqués, et le codage de la représentation codée obtenue pour obtenir une représentation compressée.
