[Insight-users] FFT Confusion

[David Doria]

As I understand it, this is one of the classes to use to perform an FFT:

VnlFFTRealToComplexConjugateImageFilter

Am I interpreting the name correctly by:

It takes a "Real" valued image and produces the "ComplexConjugate" of
the FFT as the output? If that is correct, is there instead a way to
produce the "normal" FFT (instead of the conjugate)? Or is there an
easy way to take the conjugate of a complex valued image?

Thanks,

David
