Hey everyone,
I was just wondering why when the magnitude of an image is zero, the phase is so noisy?

ok, but phase has meaning when talking about periodic signals (1d or 2d) an image can not be considered as periodic signal, so of course the phase will look like rv , do you obtain something like :
I=im2double(imread('circuit.tif'));
dI=fft2(I);
P=angle(dI);
imagesc(P)
?
