[Insight-users] help with gaussian blurring

[Karthik Krishnan]

Isabelle,

Please see Examples/Filtering/SmoothingRecursiveGaussianImageFIlter.cxx. 
The family of gaussian filters is implemented in a seperable fashion as 
perl Deriche's implementation. It is possible to set the direction 
independently and filter along any of the three axes.
