TOutput operator()(const TInput &A) const
Base class for all process objects that output image data.
void operator=(const Self &)
UnaryFunctorImageFilter< TInputImage, TOutputImage, Functor::EdgePotential< typename TInputImage::PixelType, typename TOutputImage::PixelType > > Superclass
Computes the edge potential of an image from the image gradient.
SmartPointer< const Self > ConstPointer
Implements pixel-wise generic operation on one image.
