<p class="MsoNormal">Dear all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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
<o:p></o:p></p>

<p class="MsoNormal">----FFTDirectInverse.cxx <o:p></o:p></p>
<p class="MsoNormal">----FFTImageFilter.cxx. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The input images are Data\Circle.png for FFTDirectInverse.cxx, and Data\FatMRISlice.png for FFTImageFilter.cxx.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The output image is viewed using the SNAP.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I don’t know which part is wrong. Anyone who have solved this kind of problem before?!
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Kind regards<o:p></o:p></p>
