FFT of shifted image in Numpy
I want to prove using numpy the theory of Fourier transforms in which translation in space corresponds to a shift in the phase domain (frequency domain remains constant). … I have generated these three 2d-numpy arrays showing translated versions of the same boxes:
I then use numpy to calculate the FFT of each of these images doing:
H1 = np.fft.fft2(im1)
H2 = np.fft.fft2( …
