Hi everyone,

I have a Gaussian noise corrupted image and I need to know how can I find the MMSE estimate of the entire noisy image in MATLAB? or how can I find the MMSE estimate of a Gaussian noise vector/signal (because I can divide the entire image into small patch vectors)?

Thanks.

The Image Processing Toolbox has a function immse(). Use that.

Ok thanks for your help.

I'll try to upgrade and will then see if the problem gets solved. Thanks.

Hi again.

I upgraded to MATLAB 2014b but when I checked the immse() function I came to notice that you may haven't gotten my question. My question is that I have a noisy image and I want to find its estimate/denoised version by using MMSE (minimum mean square error) as estimator, so how can I do it in MATLAB? What approach/steps should I use to get the denoised version using MMSE estimator?

Thanks.
