Patent ID: 8229240

Claim:
A computer-implemented method comprising: decomposing a first image using a first plurality of wavelet transforms, each first wavelet transform creating a first transformation resolution, each first transformation resolution having respective first data; decomposing a second image using a second plurality of wavelet transforms, each second wavelet transform creating a second transformation resolution, each second transformation resolution having respective second data; determining a first measure of texture for each first transformation resolution's respective data; determining a second measure of texture for each second transformation resolution's respective data; determining a plurality of ratios each based on a first transformation resolution's first measure of texture and a corresponding second transformation resolution's measure of texture, including computing an analog of a gradient map for each second transformation resolution based on the corresponding second transformation resolution's data; applying each first transformation resolution's first measure of texture to each corresponding second transformation resolution's data, wherein applying each first transformation resolution's first measure of texture to each corresponding second transformation resolution's data comprises applying each ratio to a corresponding second transformation resolution's data; and recomposing the second image based on the modified second transformation resolutions.
