CONCLUSIONS AND FUTURE WORK
In the present work we generalize our previous works [16, 15]. We demon-
strate that steps (1)-(6) can be applied without scale or topological restrictions.
Besides, we present a general interactive procedure to change the topology of a
surface.
The purpose of this work will be to extend the user interaction method by
using a scalpel and allowing the user to drag the scalpel.
In addition, we aim to apply the gradient vector flow (GVF), described in
Appendix A, to improve the precision of the final result. We expect that with the
proposed modifications for the GVF we will get a method less sensitive to noise
and artifacts.
Another interesting point is to implement our approach by Level Sets, instead
of T-Surfaces, following the discussion in Section 7. Finally, we expect that surface
offsets will be useful to automatically initialize dual approaches for deformable
surfaces.
