[Insight-users] FFT problem

[Yu, Yang]

Dear all,

I come across with a problem about implementing fast Fourier transform of 2D image. The output image (which is almost total gray) is not what I expected. I just simply use the codes provided by ITK examples

----FFTDirectInverse.cxx
----FFTImageFilter.cxx.

The input images are Data\Circle.png for FFTDirectInverse.cxx, and Data\FatMRISlice.png for FFTImageFilter.cxx.

The output image is viewed using the SNAP.

I don't know which part is wrong. Anyone who have solved this kind of problem before?!

Kind regards
Yang YU
