The GVF based ACM defines a new external force field [F.sup.g.sub.xt] = V(x, y), and the new external force field is named gradient vector flow force field.
The gradient vector flow force field can be expressed as V(x, y) = (u(x, y), v(x, y)), and its energy function is

Some techniques are based on a Centroidal Voronoi Diagrams (CVD) approach [13-15], whereas other methods [16-19] compute a vector field by making use of different strategies (i.e., graph cuts minimization [20], gradient vector flow [21]).
