the concave region, while the STOP and GO model actually converges to the
desired borders.
In the next experiment we are comparing the advantages of using a likelihood
map instead of other implicit classification schemes, such as that used in [5] or [12].
These approaches rely on a pseudo-mask behavior [12], which can be implemented
