You could use something like PyMedia to iterate the frames in the
video, then process the image using something like PIL or numpy.
Other possibilities might include gstreamer, or any other multimedia
library that has python bindings.  Depending on your exact needs,
python may be too slow for the "guts" of the algorithm, but certainly
could be used for prototyping and/or glue code.

I've used PyMedia with both PIL and numpy to do some video processing
in the past.  If you need help getting started, just ask.
