There is a big number of filters, but I would like to warn you: the results are usually are not as good as you would expect, and it is always done at the expense of resolution (no, resolution is NOT the size of your frame in pixels, it is the ability to resolve two close features as separate, usually, two lines). It may not justify the effort.

I can advise a couple of cross-platform C++ libraries which certainly offer noise reduction algorithms:

OpenCV. Please see:[^],[^].

CImg. Please see:[^].

Both libraries are open source.

Good luck,
