I am using the ForwardFFTImg module to analyse some images. I am
curious about the format of the frequency domain image. Since the
image is in packed format I assumed one should use FourierMagnitudeImg
to view the frequency domain. Supposedly the output from
FourierMagnitudeImg has NC/2+1 colums. When I viewed the image with
DisplayImg the image was the same size...?

How come?

Thanks,
