Abstract: An automatic image-processing method for applying a mask onto a target image includes the following steps: a) obtaining a target image, in particular an image of a face; b) for at least one area of the target image, identifying the reference points corresponding to at least the points that make it possible to define a typical case of spatial imperfection; c) for at least that area, applying at least one test for detecting spatial imperfection by comparing the target image with a reference image; d) according to the spatial imperfection detected, identifying a spatial correction mask to be applied to the area of the image including said imperfection; and e) applying the mask onto the pertinent area of the target image. An image-processing system also is provided.
