The directed distance dist([??], u, v) from u to v in [??] is the minimal length of a dipath starting from u and ending at v.
The weak diameter can intuitively be seen as an optimistic measure of the directed distances in an oriented graph (basically two vertices u and v are considered close when, say, u can reach v with few moves, and this no matter how many moves needs v to reach u (if possible)).
The complexity of deciding whether a graph admits an orientation with fixed weak diameter
It could be improved using directed distance transform (Altendorf and Jeulin, 2009) in the case of fibers with different cross-sections, but it would make the whole process more timeconsuming.
A possible solution of this problem would be to modify the method for estimating the radius of the paths, using directed distance transform (Altendorf and Jeulin, 2009).

Institutions also frequently directed distance education courses to other branches of their institution (39%) and to other college campuses (35%).

The sampled directions [vs.sub.i] of the directed distance transform are chosen as the complete neighborhood (in 2D 8 neighbors, in 3D 26 neighbors), see Altendorf (2007).
The directed distance transform can be calculated efficiently following an adapted version of the algorithm introduced by Rosenfeld and Pfaltz (1966).
