 Namespace: vigra
The functor realizes the transformation
![\[ R'G'B' \Rightarrow RGB \Rightarrow XYZ \Rightarrow L^*u^*v^* \]](form_27.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:
![\[ \begin{array}{rcl} 0 \leq & L^* & \leq 100 \\ -83.077 \leq & u^* & \leq 175.015 \\ -134.101 \leq & v^* & \leq 107.393 \end{array} \]](form_24.png)
