ABSTRACT:
Methods and systems for processing image data are described. A scene classifier determines the probabilities that various scene classes are associated with the image data. A gamut mapper determines the probabilities that various combinations of illuminant color and scene class are associated with the image data. The probabilities from the scene classifier are used to weight the probabilities from the gamut mapper. The weighted results can be used to select an illuminant color. The image data can be adjusted to compensate for the selected illuminant color.
