    The confusion resolved All of the above makes sense, once we realize that fftshift and ifftshift do not have any deep connection with fft2 and ifft2 functions. They exist only to apply circular shifts in opposite directions. And one does need these shifts...

    The time domain (or spatial domain for image processing) and the frequency domain are both continuous, infinite domains. There is no explicit or implied periodicity in either domain. This is the one I call the Fourier transform. The time domain is ......
