1. A method for correcting an image comprising: providing a first mask digital image deformed with respect to a sequence second digital contrast images in which information is represented by pixels with a lower or higher brightness level compared with a background; detecting the information pixels in the second digital contrast images from which the first image was subtracted, to obtain a binary mapping image in which the information bits at a first determined level correspond to information pixels of at least one of the second images and for which the other level bits do not correspond to information pixels in the second images; calculating coordinates of a region of interest located in the binary mapping image and at least partly covering the information bits in this image; for each second contrast image, search in the first mask image for the position of an affine mobile region of the region of interest that maximizes a similarity criterion calculated between the pixels in the region of interest fixed at its coordinates in the second contrast image and the pixels in the mobile region displaced by affine transformation in the first mask image; and estimating the correction to be made to the first mask image compared with each second contrast image being the calculated shift affine transformation, making the mobile region move from its found position at which similarity criterion is maximized to the coordinates of the region of interest.
