clear all; close all;
I = imread('64img.png','png');
I = double(I);
figure;imshow (abs(I));
title ('test')
PH=rand([64,64]);
I = I .* exp(2i*pi*PH);
FTS = fftshift (ifft2 (fftshift (I)));
A = abs (FTS);
figure; imshow (mat2gray (A));

I = imread('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1114385/image.bmp');
I = double(I);
figure;imshow (abs(I));
title ('test')
%PH=rand([64,64]);
PH = rand(size(I)); % make PH the same size as I
I = I .* exp(2i*pi*PH);
FTS = fftshift (ifft2 (fftshift (I)));
A = abs (FTS);
figure; imshow (mat2gray (A));
