activity6-Fourier Transform Model of Image

6A)


upper left: original image (circle)
upper right: fft2
lower left: fft shifted
lower right: fft shifted zoomed










upper left: original image ( bigger circle)
upper right: fft2
lower left: fft shifted
lower right: fft shifted zoomed











upper left: original image ("A")
upper right: fft2 (inverted image)
lower left: fft shifted
lower right: fft shifted zoomed









6B

upper left: image (VIP)
upper right: aperture (circle)
down: fft (inverted)















upper left: image (VIP)
upper right: aperture ( smaller circle)
down: fft (iimage not well reconstructed because of the smaller aperture size)
