Extract the RGB sensor values from a Macbeth sensor image mRGB = macbethSensorValues(sensor); These sensor RGB values from the can be transformed into the ideal RGB values for the MCC target. We can find this transform by idealLRGB = mRGB L(3x3) The transform can be adjusted to minimize different types of errors, such as the achromatic series, delta E, or RMSE. More routines will be developed for this purpose. If we find the transform L in different circumstances, say different ambient lighting for the MCC, then we can build up a whole set that is appropriate for color balancing.
