Method, system and computer program product for image modification and manipulation of a scene
View Patent ↗An automated, computerized method is provided for processing an image. The method includes the steps of providing an image file depicting an image, in a computer memory, performing an image segregation operation on the image file to generate a set of intrinsic images corresponding to the image, modifying a preselected one of the set of intrinsic images according to a set of preselected operations and merging the modified one of the set of intrinsic images relative to the set of intrinsic images to provide a modified output image.
1. An automated, computerized method for processing an image, comprising the steps of: providing an image file depicting an image defined by image locations, in a computer memory; identifying 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 single material and an illumination flux characteristic of the image; and utilizing the spatio-spectral information to identify spatio-spectral operators in the image, the spatio-spectral operators being constrained relative to one another as a function of the single material and the illumination flux characteristic in an operation to segregate the image into intrinsic images such that the intrinsic images each comprise a representation of one of the single material or the illumination flux, expressed as a separate, color band representation for the one of the single material or the illumination flux, independent of the other of the single material or illumination flux.
2. The method of claim 1 including the further step of modifying the representation of one of material or illumination, separately, to accommodate separate intrinsic characteristics of material and illumination.
3. 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 single material and an illumination flux characteristic of the image, and utilize the spatio-spectral information to identify spatio-spectral operators in the image, the spatio-spectral operators being constrained relative to one another as a function of the single material and the illumination flux characteristic in an operation to segregate the image into intrinsic images such that the intrinsic images each comprise a representation of one of the single material or the illumination flux, expressed as a separate, color band representation for the one of the single material or illumination flux, independent of the other of the single material or illumination flux.
4. The system of claim 3 wherein the computer is further arranged and configured to modify the representation of one of material or illumination, separately, to accommodate separate intrinsic characteristics of material and illumination.
5. 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: access an image file depicting an image defined by image locations, in a computer 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 single material and illumination flux characteristic of the image, and utilize the spatio-spectral information to identify spatio-spectral operators in the image, the spatio-spectral operators being constrained relative to one another as a function of the single material and the illumination flux characteristic in an operation to segregate the image into intrinsic images such that the intrinsic images each comprise a representation of one of the single material or the illumination flux, expressed as a separate, color band representation for the one of the single material or the illumination flux, independent of the other of the single material or the illumination flux.
6. The computer program product of claim 5 including the further process step to modify the representation of one of material or illumination, separately, to accommodate separate intrinsic characteristics of material and illumination.
