A method for processing an input image (20) includes applying one or more transformations (50) to the input image, whereby different shifts are applied to different pixels in the input image, so as to generate an output image (Fig. 3). A region (22) containing content (24) of interest is selected in the output image, and the region corresponding to the selected region in the output image is located in the input image. The content of the located region in the input image is substituted for the content of the selected region in the output image.

Ce procédé de traitement d'une image d'entrée (20) consiste à appliquer au moins une transformation (50) à cette image, de façon que différents décalages soient appliqués à différents pixels dans cette image, afin de produire une image de sortie (Fig. 3). Une région (22) comprenant un contenu recherché (24) est choisie dans l'image de sortie, et la région correspondant à la région choisie dans l'image de sortie est placée sur l'image d'entrée. Le contenu de la région placée dans l'image d'entrée est substitué au contenu de la région choisie dans l'image de sortie.
