Abstract

A method for processing an input image includes applying one or more transformations to the input image, whereby different shifts are applied to different pixels in the input image, so as to generate an output image. A region containing content 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.
