Detailed Description

template<class T>
class vigra::RGBPrime2YPrimeCbCrFunctor< T >

Convert non-linear (gamma corrected) R'G'B' into Y'CbCr color difference components.

#include <vigra/colorconversions.hxx>
Namespace: vigra

This functor basically applies the same transformation as vigra::RGBPrime2YPrimePbPrFunctor but the color components are scaled so that they can be coded as 8 bit integers with minimal loss of information:

\[ \begin{array}{rcl} 16\leq & Y' & \leq 235 \\ 16 \leq & Cb & \leq 240 \\ 16 \leq & Cr & \leq 240 \end{array} \]

Traits defined:

FunctorTraits::isUnaryFunctor is true (VigraTrueType)
