Give access to the Modulus of a std::complex&lt;&gt; value.
ImageAdaptor< TImage, Accessor::ComplexToModulusPixelAccessor< typename TImage::PixelType, TOutputPixelType > > Superclass
Presents a complex image as being composed of std::abs() part of its pixels.
static void Set(TInternalType &output, const TExternalType &input)
static TExternalType Get(const TInternalType &input)
Give access to partial aspects of voxels from an Image.
Base class for all data objects in ITK.
