Through image = imread (image.tiff), then Y = fftshift applied (fft2 (image)).
Viewed the spectrum through imshow (log (abs (A )),[]) as also by imshow (A, [0 100000]).
The result of the spectrum has four points in the corners. Would anyone interpret this spectrum?
Follow the link and the image obtained by FFT.
