In a first exemplary embodiment of the present invention, an automated, computerized method is provided for processing an image. According to a feature of the present invention, the method comprises the steps of providing an image file depicting an image defined by image locations, in a computer memory, generating a bi-illuminant chromaticity plane in a log color space for representing the image locations of the image in a log-chromaticity representation for the image, providing an estimate for an orientation of the bi-illuminant chromaticity plane and optimizing the estimate of an orientation as a function of a minimization of a weighted entropy. |
