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.

I'm not sure how "cool" it is, or if it's applicable to your type of noise, but a good starting place is a median filter
