Abstract

Procédé de synthèse d'images qui comprend les étapes : - d'acquisition d'au moins une image réelle (I1) par un capteur (100), - de débruitage de chaque image acquise, par une unité centrale (200), Il comprend pour chaque image obtenue à l'étape précédente, au moins une étape d'ajout d'un bruit à ladite image, par l'unité centrale (200) pour obtenir au moins une image synthétique.Image synthesis method which comprises the steps: - of acquisition of at least one real image (I1) by a sensor (100), - of denoising of each acquired image, by a central unit (200), It comprises for each image obtained in the previous step, at least one step of adding noise to said image, by the central unit (200) to obtain at least one synthetic image.
