Light weight base class for most itk classes.
Defines the inner product operation between an Neighborhood and a NeighborhoodOperator.
A NeighborhoodOperator for taking an n-th order derivative at a pixel.
ConstNeighborhoodIterator< TImage >::RadiusType RadiusType
Const version of NeighborhoodIterator, defining iteration of a local N-dimensional neighborhood of pi...
DerivativeOperator< PixelType, itkGetStaticConstMacro(ImageDimension) > dx_op
A templated class holding a n-Dimensional vector.
