* 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 ).
