What is the function used for eliminating noise using a mean flter?

On my google search I found documentation on mean filter here:

http://homepages.inf.ed.ac.uk/rbf/HIPR2/mean.htm

But I want an example source like median filter(matlab help with search is a little source with printscreens to undestand the steps for eliminating noise in an image) with source and screenshots and steps to follow like.


Any links and further information about using functions for mean filter will be very helpful! (example source with screenshots to understand how to eliminate noise for a image test ).



Thanks in advance!





J'ai trouve des documentations mais j'ai besoin d'un petit exemple ou les fonctions qui utilisent le mean filter.(pour l'elimination du bruit d'une image).




Merci d'avance!

a hint:

% if(f) you own the image proc tbx
     help mean2;
     doc mean2;

You might use mean2 as one step in creating some custom noise
reduction filter (it gets the mean of the whole image), but I think
the original poster (and perhaps what us meant) is the conv2 function
or imfilter (both in the image processing toolbox).
