Detailed Description


template<class T>
class vigra::XYZ2LabFunctor< T >

Convert standardized tri-stimulus XYZ into perceptual uniform CIE L*a*b*.

#include "vigra/colorconversions.hxx"
Namespace: vigra

The functor realizes the transformation

where is the reference white point. represents the lighness ("brightness") of the color, and code the chromaticity.
