Patent ID: 8559714

Claim:
An automated, computerized method for processing an image, comprising the steps of: providing an image file depicting an original image, in a computer memory; generating an intrinsic image corresponding to the original image, wherein the step of generating an intrinsic image is carried out according to a spatio-spectral constraint/solver model to generate a set of intrinsic images and wherein each one of the set of intrinsic images comprises a representation of one of material or illumination, expressed as a separate, multi-band representation for the one of material or illumination, wherein each band corresponds to a segment of an electro-magnetic spectrum; and modifying the intrinsic image by performing an edge-preserving blur of illumination in the intrinsic image representation of illumination, and calculate the intrinsic image representation of material as a function of the original image and the modified intrinsic image representation of illumination.
