Detailed Description


template<class T>
class vigra::RGBPrime2LuvFunctor< T >

Convert non-linear (gamma corrected) R'G'B' into perceptual uniform CIE L*u*v*.

Namespace: vigra

The functor realizes the transformation

See vigra::RGBPrime2RGBFunctor, vigra::RGB2XYZFunctor and vigra::XYZ2LuvFunctor for a description of the three steps. The resulting color components will have the following bounds:
