2.5.5.2 Special Cases of Hype rspheres in 2-D and 3-D
Next we take a deeper look into the disks (or spheres) in 2-D and 3-D for a
subclass of hyperoctagonal distances where the N-Sequence B is intrinsically
sorted (see Definition 2.22), that is, B = S(B). Examples of these disks and
spheres are shown in Figs. 2.11 and 2.12, respectively.
Under this condition, we s how that the vertices are nicely approximated
and compact forms for the perimeter, area, volume, and shape feature e xist.
Approximations of Vertices in 2-D and 3-D
We start by approximating the vertices in 2- D (digital disks) and 3-D (digital
spheres). ...
