Abstract

La présente invention concerne un procédé de calage des images telles que les images multimodales, et notamment les images entachées de bruit. En l'occurrence, on commence par convertir en énergie locale, phase locale et orientation locale les intensités des images pour donner un descripteur d'image tenant compte de la structure d'image. Sur ce descripteur d'image, on effectue des calculs de distributions de probabilités et de similitudes. Les calculs de distributions de probabilités peuvent comporter un mise en fenêtre avec une fenêtre dont les dimensions et la forme sont fonction de l'énergie locale dans l'image.
