how to proceed with image denoising based on wavelets

Respected sir, I need a matlab code for wavelet based image denoising. I do no how this wavelet works for images... Can u explain the concepts involved in denoising and matlab code for the same.

                Thanking you,

With Regards, Geetha.K

That is a very broad question, and not one appropriate for Answers. I suggest you contact your local university and ask if they have a course on the topic.

Hi Geetha, Daniel is correct that your question is very broad.

However, there is a lot of material in the Wavelet Toolbox documentation that demonstrates wavelet image denoising. For example:

http://www.mathworks.com/help/toolbox/wavelet/ug/bs3fc_j.html

and

http://www.mathworks.com/help/toolbox/wavelet/ug/bs34y5l.html

The above illustrate ways to denoise an image using GUIs and generate the MATLAB code to reproduce that analysis at the command line.
