Abstract:
1. An automated, computerized method for processing an image, comprising the steps of: providing an image file depicting an image, in a computer memory; organizing information relevant to the image according to a smooth-illumination constraint enforcing a Laplacian filter response such that ∇ utilizing the smooth-illumination constraint to generate an intrinsic image from the image, wherein the organizing includes applying the Laplacian filter response, ∇ wherein the organizing includes approximating second derivatives in the x and y directions to represent ∇ wherein the linear system of constraints is developed by applying the Laplacian filtering kernel to log-image data to generate a right-hand side of the linear system of constraints and building a left-hand matrix enforcing the same linear filtering relationship on unknown values.
