how can i implement matched,wiener and smoothing filter on this image????????

Hello

i want to implement matched,wiener and smoothing filter on this image <http://tinypic.com/view.php?pic=5wh0lg&s=5>

but i don't know how this can be done.

any one has any code related to using these filters with images?

Were there bugs in the code that you found when you google'd these?

only i got this code for wiener:

%% apply wiener filter to noisy image.

clc;

newImageRGB = imread('saturn.png');

%% convert image to gray level

grayImage = rgb2gray(newImageRGB);

figure;

imshow(grayImage);

%% adding noise to image .

afferNoise = imnoise(grayImage,'gaussian',0,0.025);

figure;

imshow(afferNoise)

%% applying wiener filter ot image.

afterWiener = wiener2(afferNoise,[6 6]);

figure, imshow(afterWiener)

and because my image is grayscale only i applied the last steps with 5*5 mask.

and i couldn't obtain the code for matched and smoothing filter.
