Base class for all process objects that output image data.
UnaryFunctorImageFilter< TInputImage, TOutputImage, Functor::GEConst< typename TInputImage::PixelType, typename TOutputImage::PixelType > > Superclass
Computes the absolute difference between an image and a constant. Can be done with ShiftScale and Abs...
TOutput operator()(const TInput &A)
Implements pixel-wise generic operation on one image.
