[Insight-users] Frequency domain filtering

[Emiliano Beronich]

Hi everybody!

I need to apply a Butterworth filter, and some others too, to an image, 
in the x-direction (unidimensional filtering to a 3D or 4D image). I 
would like to filter on the frequency domain because a need to pass the 
image across a ramp-filter, too.
Is there a convenient filter to accomplish this filtering in ITK?

Thanks
Emiliano
