[Insight-users] help with gaussian blurring

[Renaud Isabelle]

Hi,
 
I have a 3D initial image which is in fact a sequence in time of 2D images.
 
I wanna apply a gaussian smoothing on each 2D images without filtering in time, that is in z direction. 
 
How could I do? 
 
- Do I have to define my gaussian filter only on 2D image after having extracted each time a 2D image from my 3D volume,
 
- or could I define my gaussian filter on my whole 3D image ( = reader's output), but specify it to work only on x and y  directions? 
 
i take a look on the example and ITK applications but i couldn't find this case. 
 
please put a light on me,
 
isabelle
