A Novel Approach to Colour Constancy
Abstract
By approaching colour constancy as a problem of predicting colour appearance, we derive the colour constancy equation, which we use to enumerate those properties of illuminant and surface reflectance required for colour constancy. We then use a physical realisability constraint on surface reflectances to construct the set of illuminants under which the image observed can have arisen. Two distinct algorithms arise from employing this constraint in conjunction with the colour constancy equation: the first corresponds to normalisation according to a coefficient rule, the second is considerably more complex, and allows a large number of parameters in the illuminant to be recovered. The simpler algorithm has been tested extensively on images of real Mondriaan’s, taken under different coloured lights and displays good constancy. The results also indicate that good constancy requires that receptoral gain be controlled.
