In an exemplary embodiment of the present invention, an automated, computerized method is provided for processing an image. According to a feature of the present invention, the method comprises the steps of providing an image, identifying a constraint defined by spatio-spectral aspects of the image, providing an optimization function augmented by an L1, L∞ function, and utilizing the augmented optimization function to perform an optimization operation as a function of the constraint to generate an intrinsic image corresponding to the image.
