how can i . Compare reconstructed original Image of Fourier Transform

clc;
clear all;
close all;

imdata = imread('C:\Users\Th3_Bl4cK\Desktop\r.jpg');
figure(1);imshow(imdata); title('Original Image');
imdata = rgb2gray(imdata);
figure(2); imshow(imdata); title('Gray Image');

 F = fft2(imdata);

 S = abs(F);
figure(3);imshow(S,[]);title('Fourier transform of an image');

Fsh = fftshift(F);
figure(4);imshow(abs(Fsh),[]);title('Centered fourier transform of Image')

S2 = log(1+abs(Fsh));
figure(5);imshow(S2,[]);title('log transformed Image')

F = ifftshift(Fsh);
f = ifft2(F);
figure(6);imshow(f,[]),title('reconstructed Image')

In figure(7) I want to show the rgb image of original image .

Try this:

imdata = imread('C:\Users\Th3_Bl4cK\Desktop\r.jpg');
figure(1);
imshow(imdata); 
originalRGBImage = imdata; % Save original image for later display in figure (7)
title('Original Image');
imdata = rgb2gray(imdata);  % imdata changed, so good thing we saved it.
% more code....
% Now display original image in figure 7
h7 = figure(7);
imshow(originalRGBImage);
