The theoretical comparison of efficiency of the algorithms for directional field constructing

In this paper the theoretical and experimental investigations of efficiency of known algorithms for directional fields constructing (by criterion of noise stability) are presented. An analysis carried out by us provides the conditions for exceeding the algorithm described in over the algorithm described in. It is shown, that this superiority is caused by principal features of a structure of algorithms. As well, the conditions for approximately identical noise stability of both these algorithms are formulated.
