Image noise detection and reduction

Asked by Ömer KAYA on 4 Feb 2011

I am in need of an image noise detection and reduction algorithm.


Jan Simon on 4 Feb 2011

Please specify any Matlab specific details.

Walter Roberson on 4 Feb 2011

And just any algorithm with do? If that's the case, set the entire image to a constant value and there will be no more noise. If that solution is not acceptable, then you need to be more specific about the kind of images and kind of noise that you are working with.

Please edit the subject line! "Hello;" is not a good subject for this question.
