Hey I want to change my gray image back to rgb.
This is my code
I1 = '3 new.jpeg';
img = imread(I1);
img_grey = rgb2gray(img);
A = img(:,:,3);
second_img = imsubtract(A, img_grey);
final_img = im2bw(second_img, 0.09);
imshow(final_img);
title('Final Img','fontsize',20);
rgbImage=ind2rgb(final_img,jet(256));
imshow (rgbImage);

rgbImage=ind2rgb(uint8(final_img), jet(256));
You will not be able to convert it back to the original color.
However it would be possible to use the binary image to select parts of the original image to stay the same and convert everything else to black.
finalrgb = img.*uint8(final_img) ;

How did you call the display function, such as imshow(), in both cases? It should work the same. Are you using GUIDE or App Designer for the "GUI" method?
To change your gray scale image back into the original RGB image, you simply assign it:
img_grey = img;
That should work as long as you still have img available.

We recommend against using global.

subplot('Position', [0.2 0.2 0.6 0.6]);
subplot() of what axes in what figure?
Note: when you use subplot() and the position you give partly overlays an existing axes, the existing axes will be deleted.
img_grey=img;GUID
is GUID a function that you are intentionally calling there?
Note that in pushbuttoon2_Callback, you do not display anything.

Attach both the .m file and the .fig file with the paperclip icon if you need more help.
