[Insight-users] quick question: discrete or recursive gaussian filter

[Renaud Isabelle]

Hi,
 
Now, thanks for all your replies, I think I caught the way to use itkDiscreteGaussianImageFilter and itkRecursiveGaussianImageFilter. 
 
But, something is still not obvious for me: 
 
for, small recursive sigma value and/or small discrete variance value, could someone tell me what is better to use between itkRecursiveGaussianImageFilter and itkDiscreteGaussianImageFilter, in terms of time computation and precision results?
