Significance of phase and amplitude in the Fourier domain

We add new thoughts and aspects to the importance of phase and amplitude in the Fourier domain. We show how very similar objects react radically differently if, in the Fourier domain, either the phase was lost completely or the amplitude was modified to be constant. We also discuss the great influence of symmetry on the relative significance of the Fourier amplitude and of the Fourier phase. We show how changing the value of one pixel in some objects completely changes the significance of the Fourier phase and amplitude.
