WebSep 26, 2014 · Multiplying by purely complex exponential is basically a phase shift. If you shift original image, the amplitude of its frequency components remains the same, the only thing that changes is the phase of those components. That's the shifting property of an FFT. Shifting is done by moving the origin point of an image.
