Warning while trying to filter RGB values on a picture

13 views (last 30 days)
Hi All,
The following is my code:
I = imread('29_11_2019_132519Mosaix.jpg');
rmat = I(:,:,1);
gmat = I(:,:,2);
bmat = I(:,:,3);
binaryImageR = rmat < 50;
rmat(binaryImageR) = 0;
binaryImageG = gmat < 50;
gmat(binaryImageG) = 0;
binaryImageB = bmat < 50;
bmat(binaryImageB) = 0;
imageSum = (rmat & gmat & bmat);
figure;
subplot(2,3,1), imshow(binaryImageR);
title('Red Plane');
subplot(2,3,2), imshow(binaryImageG);
title('Green Plane');
subplot(2,3,3), imshow(binaryImageG);
title('Blue Plane');
subplot(2,3,4), imshow(imageSum);
title('Filter Sum');
subplot(2,3,5), imshow(I);
title('Original');
I get the following warning and am not certain of how to fix it.
Any help will be much appreciated!

Assuming you are using the Live Editor, as a workaround, you can add the following command immediately after your plotting command(s):
>> uicontrol('Visible','off')
This will prevent the figure from being serialized, and hence most likely will prevent the error from occurring. Note, though, that this will cause the figure to then both be displayed in the Live Script and in a new figure window.
Hope this helps!
