Abstract
In a first exemplary embodiment of the present invention, an automated, computerized method is provided for determining an illumination boundary in an image. The method comprises the steps of performing dynamic sampling in preselected local areas of the image to determine spectral ratio information for the image at each of the preselected local areas, and utilizing the spectral ratio information to identify an illumination boundary.
