Phase and Magnitude Fourier transform of a real function is complex –difficult to plot, visualize –instead, we can think of the phase and magnitude of the transform Phase is the phase of the complex transform Magnitude is the magnitude of the complex transform Curious fact – all natural images have about the same magnitude transform – hence, phase seems to matter, but magnitude largely doesn't Demonstration – Take two pictures, swap the phase transforms, compute the inverse - what does the result look like
