Claim 1
Independent Claim
78 words
A method for characterizing a scene as surfaces and illuminants comprising the steps of: measuring an illuminant spectral signature of a capturing device 110; capturing the scene as an array of pixel values 150; characterizing a scene transfer function by combining the illuminant spectral signature with a device signature of the capturing device 130; and characterizing a scene signature by describing illumination and surfaces corresponding to the array of pixel values according to the scene transfer function 160.
