[Walter Roberson]

I = imread('YourImage.jpg');
blurredI = I + max(I(:)) / 10 * rand(size(I);
imwrite(blurredI, 'BlurredImage.jpg');

[Sneha Chakurkar]

its showing Error. Code is wrong.

[Walter Roberson]

filename = 'flamingos.jpg';
I = imread(filename);
imshow(I); title('original');

blurredI = cast(double(I) + double(max(I(:))) / 10 * rand(size(I)), 'like', I);
imwrite(blurredI, 'BlurredImage.jpg');

imshow(blurredI)

diffI = imsubtract(blurredI, I);
imshow(rescale(diffI))

Try this:

fontSize = 15;

% Blur a gray scale image.
windowSize = 19;
kernel = ones(windowSize) / windowSize ^ 2;
grayImage = imread('cameraman.tif');
subplot(2, 2, 1);
imshow(grayImage);
title('Original Image', 'FontSize',fontSize);
blurryImage = imfilter(grayImage, kernel);
subplot(2, 2, 2);
imshow(blurryImage, []);
title('Blurred Image', 'FontSize',fontSize);

% Blur an RGB image.
windowSize = 19;
kernel = ones(windowSize) / windowSize ^ 2;
rgbImage = imread('peppers.png');
subplot(2, 2, 3);
imshow(rgbImage);
title('Original Image', 'FontSize',fontSize);
blurryImage = imfilter(rgbImage, kernel);
subplot(2, 2, 4);
imshow(blurryImage, []);
title('Blurred Image', 'FontSize',fontSize);
