In a first exemplary embodiment of the present invention, an automated, computerized method for generating an illumination invariant, chromaticity representation of an image is provided. The method of the present invention comprises the steps of providing an image comprising an array of pixels, each pixel having N band color values, transforming the N bands to log color space values in a log color space, generating a bi-illuminant chromaticity plane in the log color space and projecting the log color space values to the chromaticity the plane to provide chromaticity representation values corresponding to the pixels of the image.
