Abstract: The present invention provides a method for analyzing a digital image comprising a plurality of pixels representing a scene. The method comprising steps of obtaining pixel chromaticity information, providing, combinations each having a corresponding surface and a corresponding illuminant, performing a global scene surface-illuminant classification by determining hypothesis scores, accumulating hypothesis scores, thereby obtaining a global illuminant/surface statistic representing an estimate of a distribution of illuminants and/or surfaces in the scene as represented by the digital image. Other methods are also provided. Apparatuses for carrying out the methods are also provided.
