In the tutorial, a rectangle is drawn. Average brightness is then calculated only within that rectangle, and not over the whole image. But the video is a pan shot. And the rectangle's position and size is static. So the rectangle does not track the same part of the picture. Even with an image sequence from a locked-down camera a similar need can emerge. You might want a moving object to maintain its brightness over the sequence of shots. Would it be possible to allow a more dynamic specification of that rectangle?
