Users are asked to annotate the 4 extremal points (left, right, top, and bottom-most) of an object. The authors of the paper claim, that this is a more natural way of defining bounding-boxes of objects.
Implementation remarks:
the clicking order does not matter
it's not possible to move the whole box. Instead one can drag the single points with right button move.
