Title (EN) METHOD AND DEVICE FOR DIGITAL IMAGE RESTORATION
(FR) PROCÉDÉ ET DISPOSITIF DE RESTAURATION D'IMAGE NUMÉRIQUE
Abstract:
(EN) The invention concerns a method and a device for digital image restoration. The digital image to be restored comes from an initial image acquired by an image acquisition device having an associated acquisition instrumental noise. The method comprises the following steps: - obtaining (30) an intermediate digital image with restoration of the acquisition instrumental noise, - denoising (32) the intermediate digital image in order to obtain a denoised intermediate digital image, - deconvolution (34) of the denoised digital image in order to obtain a restored digital image.
(FR) L'invention concerne un procédé et un dispositif de restauration d'image numérique. L'image numérique à restaurer étant issue d'une image initiale acquise par un dispositif d'acquisition d'image ayant un bruit instrumental d'acquisition associé. Le procédé comporte les étapes suivantes : - obtention (30) d'une image numérique intermédiaire avec restitution du bruit instrumental d'acquisition, - débruitage (32) de l'image numérique intermédiaire pour obtenir une image numérique intermédiaire débruitée, - déconvolution (34) de l'image numérique débruitée pour obtenir une image numérique restaurée.
