Abstract
A system that compensates for uneven lighting in a digital image of a surface. During operation, the system receives the digital image of the surface. Next, the system obtains a reference lighting map for the surface, which contains information about the lighting of the surface at the time the digital image was acquired. The system then uses the reference lighting map to compensate for uneven lighting in the digital image.
