blur an image of a mandrill in matlab

To blur an image of a mandrill in Matlab, you can follow these steps:

1. Load the image using imread function
2. Convert the image to grayscale using rgb2gray function
3. Create a Gaussian filter using fspecial function
4. Apply the filter to the grayscale image using imfilter function

Here's the code:

main.m
% Load the image
im = imread('mandrill.png');

% Convert to grayscale
im_gray = rgb2gray(im);

% Create a Gaussian filter
h = fspecial('gaussian', [5 5], 2);

% Apply the filter
im_blur = imfilter(im_gray, h);

% Display the original and blurred images
figure
subplot(1, 2, 1)
imshow(im_gray)
title('Original Image')

subplot(1, 2, 2)
imshow(im_blur)
title('Blurred Image')

22 lines

You can adjust the size and standard deviation of the Gaussian filter to control the amount of blur in the image.
