1. A computer implemented method of producing accented image data for an accented image including the steps of: a) decomposing, using at least one computer processing device, each of a first and a second image into a gradient representation which comprises spectral and edge components; b) combining, using at least one computer processing device, the edge component from the first image with the spectral component from the second image to form a combined gradient representation; and c) generating, using at least one computer processing device, accented image data for the accented image from data including the combined gradient representation.
