Say that the *concavity* of a polyhedron (2D or 3D) equals the number of points laying within the convex hull. Could (in principle) the measures you propose give different results? --> different 'types' or 'characters' of 'concavity'? Or, differently, the least count of points to be removed so as to *obtain* a convex figure. (more tricky) Wouter.
