A circle is drawn with B
boundary points. Chords are drawn from each
boundary point to every other
boundary point.
Definition 7 (Hole
Boundary Points (HBP)): HBPs are the intersection points of nodes' sensing discs around a coverage hole, which develop an irregular polygon by connecting adjacent points.
If the Nr is too small, some valid boundaries will not be detected where the point density is large; on the contrary, if the Nr is too large, the
boundary points will contain more noise, which will influence the accuracy of 3D model badly.
The spline-interpolation solution is particularly effective in comparison with the FEM for the bodies with singular
boundary points, for example, cones [14].
D.I.KHAN -- Security forces Wednesday evening here gunned down a suicide bomber before he could hit the check post in Chudwan area, situated at the
boundary point connecting D.I Khan district with tribal belt, local police said.
For each sampled point on the circle, its nearest
boundary point is found and lined to it.
A grid point is called a
boundary point if i = 0,I or j = 0, J; otherwise, it is called an interior point.
This could be done by using
boundary point tracking algorithm [17].
Without loss of generality, one can consider only the left
boundary point [u.sub.0] = ch, 0 < c < 1, if [U.sub.t] takes value only from [0,1].
