Detailed Description
class vigra::RGBPrime2LuvFunctor< T >
Convert non-linear (gamma corrected) R'G'B' into perceptual uniform CIE L*u*v*.
#include <vigra/colorconversions.hxx>
Namespace: vigra
The functor realizes the transformation
![\[ R'G'B' \Rightarrow RGB \Rightarrow XYZ \Rightarrow L^*u^*v^*
\]](form_46_dark.png)
See vigra::RGBPrime2RGBFunctor, vigra::RGB2XYZFunctor and vigra::XYZ2LuvFunctor for a description of the three steps. The resulting color components will have the following bounds:
![\[ \begin{array}{rcl}
0 \leq & L^* & \leq 100 \\
-83.077 \leq & u^* & \leq 175.015 \\
-134.101 \leq & v^* & \leq 107.393
\end{array}

Traits defined:
FunctorTraits::isUnaryFunctor is true (VigraTrueType)
