Detailed Description

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

Calculate the variance in the neighborhood of a pixel.

Calculate the variance pixel value over the standard 8, 26, etc. connected neighborhood. This calculation uses a ZeroFluxNeumannBoundaryCondition.

If called with a ContinuousIndex or Point, the calculation is performed at the nearest neighbor.

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