Title (EN) EARLY TERMINATION OF BLOCK-MATCHING FOR COLLABORATIVE FILTERING
(FR) TERMINAISON PRÉCOCE D'APPARIEMENT DE BLOCS D'IMAGES POUR FILTRAGE COLLABORATIF
Abstract:
(EN) The present disclosure relates to the iterative fast-search of more than one K-integer best blocks, corresponding to best patches, by early termination of the subblock iteration through a similarity threshold. In particular, the positions of k-best matched-blocks, divided into multiple subblocks, are found for a reference block within an image search area, by performing subblock-based iterative calculations of the similarity between a block at a current position and the reference block within a search area. The iteration progresses as long as the similarity remains larger than a threshold with the K-best patches being recorded, whereas the subblock iteration terminates when the similarity is lower than a threshold.
(FR) La présente invention concerne la recherche rapide itérative de plusieurs K-meilleurs blocs en nombre entier, correspondant aux meilleurs carreaux, par une terminaison précoce de l'itération de sous-blocs au moyen d'un seuil de similarité. En particulier, les positions des K-meilleurs blocs appariés, divisés en plusieurs sous-blocs, sont déterminées pour un bloc de référence dans une zone de recherche d'image, en effectuant des calculs itératifs à base de sous-blocs de la similarité entre un bloc à une position actuelle et le bloc de référence à l'intérieur d'une zone de recherche. L'itération progresse tant que la similarité reste supérieure à un seuil, les K-meilleurs carreaux étant enregistrés, tandis que l'itération de sous-blocs se termine lorsque la similarité est inférieure à un seuil.
