The property
of filling ratio of a resulting segment is defined as follows:

Where

t_1, t_2... t_m
- coordinates of points of the raster;

E (t_i, h) - |
membership function which is determined
by parameters of the found maximum (h = {X, Y, A, D, P1, P2, B1, B2}); |

e (t_i) - |
the indicator function marking contour
points: = 1 if the given raster point is included into the number of contour points; = 0, otherwise. |

In the first
series of experiments those segments were only considered acceptable
which have filling ratio over 0.5.

According to*
sparsed* representation, the filling ratio criterion of contiguous
segments was modified also. The essence of such modification consists
in the following. The axial line of a tested segment is divided into
the intervals equal to a step of tracking of contour boundaries. Within
the limits of each interval there is the contour point nearest to the
axial line. Values of memberships functions to these points are summarized,
and the obtained outcome is divided on the greatest possible value of
this sum when within the limits of each interval there is a point laying
on the segment axial line. In the second series of experiments the segments
which filling ratio exceeded 0.8 were considered as acceptable ones.
