Edge detection and sharpening software is my friend. If it's an object in
the frame, contrast to the entire frame, that is being target then run a
simple edge detector on a blit, find the CG, stack CG in subsequent
frames. Average, sharpen, edge detect, add back into original (ie stack
frames)...

Another trick, digital cameras use it, is to crop all the frames so that
the 'window' is the 'same' in each frame. Then display the frame as the
'through the lens' and you get a much more stable image.

That they are moving is an opportunity, not a problem.
