[Insight-users] FFT, convolution

[alexandre govignon]

hi everybody...

I have an important on FFT in Itk and convolution...
I want to know all about this FFT. I don't think about license...

But on specification of the FFT:

Anti-aliasing and zero padding?

Can you help me?

Generally speaking I would like know if i have someting to change at
my code when i use the vnlFFT library on itk... in order to avoid
image noise and everything else like this on my image results.

Thank you for advance.
