That's the point: make another filter with temporal dimension in blend.
Blend filter has many features such as doing something more than diff
and having threading. The main function takes 2 frames so just add the
glue code around to take the previous and the current frame instead.

That's just a suggestion, maybe the other functions don't make much sense.
Feel free to ignore.
