* \class AmplitudePhaseToRGBFunctor
* \brief Function object to compute a color representation of a radar image.
*
* This class is useful for visualizing radar images with a combination of
* the phase and the amplitude at the same time.
*
* The amplitude is used to represent the intensity of the pixel and the phase
* to represent it's hue.
*
* Amplitude and phase can be obtained using the itk::ComplexToModulusImageFilter
* and itk::ComplexToPhaseImageFilter for example.
