Class handling the surface moment.
For a dense planar object, the area corresponds to the zero-order moment:
When considering a discrete set of points, the moment simply corresponds to the number of points. Since this is of no use in a servoing scheme, this class uses in this case , which is invariant to planar translation and rotation.
