要約
(EN)
The present invention provides an information processing device in which a degradation process of an input image is accurately estimated and a dictionary necessary for generating a desired restored image from the input image can be obtained. The information processing device is provided with: an image acquisition means that acquires a plurality of study images and an input image; and an estimation means that, on the basis of similarity between an arbitrary region of the input image and each of a plurality of degradation images in a case where regions of the study images corresponding to the arbitrary region are degraded on the basis of each of the plurality of degradation processes, outputs an estimated degradation process corresponding to the degradation process corresponding to the region of the input image.

La présente invention concerne un dispositif de traitement d'informations dans lequel un traitement de dégradation d'une image d'entrée est estimé de manière précise et un dictionnaire nécessaire pour générer une image restaurée souhaitée à partir de l'image d'entrée peut être obtenu. Le dispositif de traitement d'informations comporte : un moyen d'acquisition d'image qui acquiert une pluralité d'images d'étude et une image d'entrée ; et un moyen d'estimation qui, sur la base d'une similarité entre une région arbitraire de l'image d'entrée et chacune d'une pluralité d'images de dégradation dans un cas dans lequel des régions des images d'étude correspondant à la région arbitraire sont dégradées sur la base de chacun de la pluralité de traitements de dégradation, délivre un traitement de dégradation estimé correspondant au traitement de dégradation correspondant à la région de l'image d'entrée.
