A similar code is in the stabilization plugin. It detects motion of subsequent
frames and writes it into a file.
Since it uses small measurement fields one can also detect small
moving objects, however the code has to be modified a bit. Just a though....
This kind of motion detection would be better than a simple difference image,
because brightness changes and so on are no problem, but off course it is
slower.
