First Claim
Patent Images
1. A machine-based method for use in processing a digital image that includes first and second regions, the method comprising:
- estimating an intrinsic color of a given pixel located in an area of interest that is adjacent to at least one of the first and second regions, the estimating comprises extrapolating from colors of multiple pixels in one of the first and second regions and multiple pixels in the other of the two regions, andstoring the intrinsic color of the pixel for later use.

Abstract
A digital image that includes first and second regions is processed. An intrinsic color of a given pixel located in an area of interest that is adjacent to at least one of the first and second regions is estimated by extrapolating from colors of multiple pixels in one of the first and second regions and multiple pixels in the other of the two regions.
