<div dir="ltr">Hi there,<div><br></div><div>I'm attempting to perform a Fast Fourier Transform (FFT) on an image using ITK. For my test data, I am unable to use the ForwardFFTImageFilter, which throws an exception on Update(). This exception is in regards to the dimension sizes of the image (must be a multiple of 2,3, or 5). Thus I am looking to use FFTW.</div>
<div><br></div><div>On my Windows 7 machine, in my ITK cmake configuration, I have set ITK_USE_SYSTEM_FFTW to be true. This was because there were error messages on setting ITK_USE_FFTWD indicating that for Windows, I must use ITK_USE_SYSTEM_FFTW as fftw cannot be built as an external project on Windows.</div>
<div><br></div><div>In my VS 2008 project, upon building the solution, I hit an error "FFTW 3.3.2 or later is required so that FFTW_WISDOM_ONLY is defined." This indicates to me that FFTW was not found. </div><div>
<br></div><div>Searching the ITK mailing list archive, I did not find a clear solution to this.</div><div><br></div><div>Does anyone know or have a solution for using FFTW in ITK on a Windows machine?</div><div><br></div>
<div>Thank you.</div><div><br></div><div>Cheers,<br clear="all"><div><div dir="ltr">Ricky Singla </div></div>
