#include <itkForwardDifferenceOperator.h>
Inheritance diagram for itk::ForwardDifferenceOperator< TPixel, VDimension, TAllocator >:
ForwardDifferenceOperator uses forward differences i.e. F(x+1) - F(x) to calculate a "half" derivative useful, among other things, in solving differential equations. It is a directional NeighborhoodOperator that should be applied to a Neighborhood using the inner product.
