<DIV>Thanks Jesse. I totally agree about the lack of documentation. </DIV> <DIV> </DIV> <DIV>I think I will give up using itk FFTW as well, for the second time! </DIV> <DIV> </DIV> <DIV>I would like only to use Vnl version, however, it seems this one produces the wrong result. </DIV> <DIV> </DIV> <DIV>Could you tell me on what you tried to make itk FFTW work: Windows with Microsoft Visual C++? </DIV> <DIV> </DIV> <DIV>Isabelle<BR><BR><B><I>Jesse C Cronce <croncejc@mrctr.upmc.edu></I></B> a écrit :</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">I tried using the fft functionality provided by the different filters<BR>and was never able to get it to work.
