asd.pngwhen you activate the file. four image should appear like this.
img1, img2, img1 magnitude + img2 phase , img1 phase + img2 magnitude . 2D DFT method should be used in last two image (seperating magnitude and phase)

Do the same for considering two images and show mag1+phase1 and so on, here I have shown how you calculate the mag and phase for one image
fft_result=fft2(im);
mag=abs(fft_result);
phase=angle(fft_result);
