I want to ask...is it possible to differentiate 2 different images by
using the fft2 function in matlab?
If i'm not mistaken, fft2 converts the image into cos and sin
function..Is it possible to differentiate the images (power spectrum
image) by looking only at its phase and magnitude diagram?thanks..
