[Insight-users] Speeding up the evaluation of the itk::Gaussian?

[motes motes]

In a loop that iterates a 128*128 image I am currently using a 2D itk::Gaussian:


#include "itkGaussianSpatialObject.h"
....

  ti.GoToBegin();

  while(!ti.IsAtEnd())  {

      .....
      InputPointType translated = tmp + (location-point);
      double value;
      m_Gaussian->ValueAt(translated, value);
      ....

}

but it totally kills the performance (without the gaussian call it
takes seconds and with the gaussian call it takes minutes!). Is there
someway to speed up the evaluation of the 2D  itk::Gaussian ?
