1. A method for the processing of images produced by an radioscopic apparatus, the method comprising: exposing a patient's body to radiation; obtaining a raw image representing an internal structure of the body through a detector; determining a family of directional 2D filters, to be applied to the raw image; convoluting the raw image successively with one or more filters of the family of directional 2D filters; obtaining from responses of the one or more filters of the family of 2D filters, a confidence map in which each pixel is assigned a confidence value corresponding to the responses of the one or more filters of the family of 2D filters; determining a de-noising filter, the parameters of which are computed, for each pixel, as a function of the raw image and of the corresponding confidence map; applying the de-noising filter to the raw image to produce a de-noised image output; producing an enhanced image in which, for each pixel of the raw image, an intensity of the grey levels of said pixel is enhanced relative to the predefined immediate environment of said pixel; producing a fusion image by combining the raw image with the enhanced image and the de-noised image, pixel by pixel, as a function of the value of said pixel in the confidence map; and displaying the fusion image for viewing.
