The thesis documents various implementations of the
spherical self-organizing feature map spanning from
range imagery to multi-dimensional satellite imagery.
Other implementations include archaeological data
and face modeling. The techniques are adapted
versions of the fundamental learning strategy of the
self-organizing map, introduced by Dr. Teuvo Kohonen,
and implemented within a spherical topology.
Continuity in learning is imposed by the predefined
spherical lattice which also transforms the data into
a 3D tessellated form. Since the tessellated forms
originate from a sphere they simplify the computation
of transformation parameters, object re-orientation
etc. commonly used in three-dimensional graphics.
