[Insight-users] bandpass filter in ITK

[barbababa]

Hello!

Yes i guess that is correct. In my understanding one takes the fft of the
image, applies a mask shaped
like a donut, with inner ring defining the lower cutoff and outer ring the
high cutoff untill the nyquist limit. Everything lower and higher than these
will be cut off.
And then the inverse fft.

Is this the same?
