- No images are attached
- In what way is it not working? Do you get an error? Or a different result than you expect (in which case what did you expect?)?
- What exact code did you use. It's going to be difficult to tell you what's wrong if you don't tell us.

Two points you may have overlooked.
- You need to do it on monochrome images, not color. So extract the color channels and do it one color channel at a time.
- You need to cast the uint8 to double before you pass the array into conv2.

windowSize = 9;
kernel = ones(windowSize)/windowSize^2;
blurredImage = conv2(double(grayImage), kernel, 'same');
surf(blurredImage);
colormap(gray(256));
