[Insight-users] help on the FFT and FFT Inverse

[Luis Ibanez]

Hi Remi,

Please look at the FFT examples in


    Insight/Examples/Filtering/
                 FFTImageFilter.cxx


You must pay particular attention to the pixel type that
you use for representing your images.

If you continue experiencing any problems with the FFT,
then please post your code to the list.


    Thanks


      Luis
