A pixel cloning technique allows for digital image retouching of a digital image. Initially, a cloned area and a surround area are determined. Using the image pixel values, the mean, slope, and quadratic coefficients in each color are computed for the cloned area and the surround area, and, if desired, for subregions of the surround. If subregions are used, it is determined which subregion of the surround deviates the least from the functional model. The values of the cloned pixels are adjusted so that their mean, slope, and quadratic term match the mean, slope, and quadratic term of the surround, or of the best fitting subregion of the surround.
