[Insight-users] Obtaining Real Result from Inverse Fourier Transform

[DVigneault]

Thanks for the reply, Brad!

When I change the typedef to:

typedef itk::VnlInverseFFTImageFilter< ComplexImageType, ComplexImageType > 
FFTInverseFilterType;

I get a very long error message during compilation, which starts with:
