BinaryFunctorImageFilter< TInputImage1, TInputImage2, TOutputImage, Functor::ConstrainedValueDifference< typename TInputImage1::PixelType, typename TInputImage2::PixelType, typename TOutputImage::PixelType > > Superclass
Base class for all process objects that output image data.
TOutput operator()(const TInput1 &A, const TInput2 &B) const
Implements pixel-wise the computation of constrained value difference.
bool operator!=(const ConstrainedValueDifference &) const
Define additional traits for native types such as int or float.
#define itkConceptMacro(name, concept)
Implements pixel-wise generic operation of two images, or of an image and a constant.
bool operator==(const ConstrainedValueDifference &other) const
