#include <itkGaussianSpatialFunction.h>

Detailed Description

template<typename TOutput = double, unsigned int VImageDimension = 3, typename TInput = Point<SpacePrecisionType, VImageDimension>>
class itk::GaussianSpatialFunction< TOutput, VImageDimension, TInput >

N-dimensional Gaussian spatial function class.

GaussianSpatialFunction implements a standard Gaussian curve in N-d. m_Normalized determines whether or not the Gaussian is normalized (whether or not the sum over infinite space is 1.0)

m_Scale scales the output of the Gaussian to span a range larger than 0->1, and is often set to the maximum value of the output data type (for instance, 255 for uchars)
