Title (EN) METHOD AND DEVICE FOR CLUSTERING PATCHES OF A DEGRADED VERSION OF AN IMAGE
(FR) PROCÉDÉ ET DISPOSITIF POUR GROUPER DES PIÈCES D’UNE VERSION DÉGRADÉE D’UNE IMAGE
Abstract:
(EN) Clustering patches of a degraded version of an image is such that the clusters are based on errors computed between patches of the degraded version processed with upgrade functions associated respectively with the clusters and patches of a full graded version of the image corresponding respectively to the patches of the degraded version. The source image is thus used to determine clusters for the image to restore. A restoration framework based on a clustering according to the present principles is also disclosed.
(FR) L’invention concerne le groupement de pièces d’une version dégradée d’une image, qui est tel que les groupes sont basés sur des erreurs calculées entre des pièces de la version dégradée traitées avec des fonctions de mise à niveau associées respectivement aux groupes et des pièces d’une version entièrement gradée de l’image correspondant respectivement aux pièces de la version dégradée. L’image source est ainsi utilisée pour déterminer des groupes pour l’image à restaurer. Un cadriciel de restauration basé sur un groupement selon les présents principes est également proposé.
