Perhaps you should provide a link to some of the images you want to filter
for noise, so we can get an idea.
It really depends on what size the dust and scratches are, and how easily
they can be distinguished from real content.
Usually to filter noise, you need some edge-preserving smoothing filter. One
very interesting article I read was about the SUSAN filter.
