Method for image modification

A computer program product, disposed on a non-transitory computer readable media, the product including computer executable process steps operable to control a computer to:

• provide an image file depicting an image, in a computer memory, perform an image segregation operation on the image file to generate a set of intrinsic images corresponding to the image, modify a preselected one of the set of intrinsic images by a geometric transformation and merge the modified one of the set of intrinsic images relative to the set of intrinsic images to provide a modified output image.

A computer program product, disposed on a non-transitory computer readable media, the product including computer executable process steps operable to control a computer to:

• provide an image file depicting an image, in a computer memory, perform an image segregation operation on the image file to generate a set of intrinsic images corresponding to the image, 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, independent of the other of the material or illumination, wherein each band corresponds to a segment of the electro-magnetic spectrum, and modify each one of the set of intrinsic images, separately, to accommodate separate intrinsic characteristics of material and illumination, for a more accurate result.

A system for processing an image, comprising:

• a memory storing an image file depicting an image defined by image locations, and
• a computer arranged and configured to execute a routine to access the image file in the memory, identify spatio-spectral information for the image, the spatio-spectral information defining spectral relationships, expressed in color bands, among contiguous image locations, and the spatial extent of the spectral relationships, as relevant to a material and illumination characteristic of the image, and utilize the spatio-spectral information to segregate the image into intrinsic images such that the intrinsic images each comprise a representation of one of material or illumination, expressed as a separate, color band representation for the one of material or illumination, independent of the other of the material or illumination.
