Abstract[English]
Various embodiments provide methods, apparatuses, and computer program products. An example apparatus includes at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform: using a first neural network (NN) filter for filtering a first set of frames of a video; using a second NN filter for filtering a second set of frames of the video; wherein the first NN filter comprises a base or pretrained NN filter and the second NN filter comprises an overfitted or updated NN filter; wherein the base or pretrained NN filter is available at the apparatus as part of the apparatus; and wherein the overfitted or updated NN filter is derived at the apparatus based at least on an update received from an encoder.[French]
Divers modes de réalisation concernent des procédés, des appareils, et des produits-programmes informatiques. Un appareil donné à titre d'exemple comprend au moins un processeur; et au moins une mémoire stockant des instructions qui, lorsqu'elles sont exécutées par l'au moins un processeur, amènent l'appareil au moins à : utiliser un premier filtre de réseau neuronal (NN) pour filtrer un premier ensemble de trames d'une vidéo ; utiliser un second filtre NN pour filtrer un second ensemble de trames de la vidéo ; le premier filtre NN comprenant un filtre NN de base ou pré-entraîné et le second filtre NN comprenant un filtre NN surajusté ou mis à jour ; la base ou le filtre NN pré-entraîné étant disponible au niveau de l'appareil en tant que partie de l'appareil ; et le filtre NN surajusté ou mis à jour étant dérivé au niveau de l'appareil sur la base au moins d'une mise à jour reçue d'un codeur.
