fastNlMeansDenoising with Python

edit

I'm having trouble with cv2.fastNlMeansDenoising(). I'm running Python 2.7 on Windows 7 (forced to use Windows since it's a work computer...otherwise I'd be on linux). Is this a c++ only function? The documentation doesn't refer to Python but surely there is a denoising function for Python. When I execute fastNlMeansDenoising my application locks up.
