[Insight-users] FFT

[Luis Ibanez]

Hi Alexandre,


0) The fact that the image is being read
    from a DICOM file format is irrelevant
    for the purpose of computing an FFT.


1) Have you enabled FFTW ?


2) Have you run the examples:

    Insight/Examples/Filtering/
      FFTDirectInverse.cxx
      FFTDirectInverse2.cxx
      FFTImageFilter.cxx


3) In particular have you tried the following ?

FFTImageFilter.exe
    Insight/Examples/Data/Circle.png circleReal.mhd circleImg.mhd



Please let us know,


    Thanks


       Luis
