Detailed Description

template<class TInputImage, class TCoordRep = float>
class itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >

Calculate the derivative by central differencing.

This class is templated over the input image type and the coordinate representation type (e.g. float or double).

Possible improvements:

• the use of Neighborhood operators may improve efficiency.
