You can use medfilt2 to perform 2D median filtering on an image. Example:

% Read image
img = imread('yourimage.jpg');

% Median filtering
filtered_img = medfilt2(img);

You can use fspecial to create a Gaussian filter and use imfilter to filter the image with that filter. Example:

% Read image
img = imread('yourimage.jpg');

% Gaussian filter of size 11-by-11 and std 3 pixels
h = fspecial('gaussian', 11, 3);

% Convolve
filtered_img = imfilter(img, h);
