Performs color calibration using a color chart.
Performs color calibration using a color chart.
The calibration in performed in the specified reference color space. For the best results the reference color space should be similar to the color space of the input image. That is, in optimal conditions function mapping from the actual color space to the reference color space should be close to linear. For instance for raw images the CIE XYZ color space is better reference than sRGB since mapping between the input and the reference can be done with good accuracy using low order polynomial. If the input image is a typical JPEG image it is best to select sRGB as a reference color space.
