Topological Equivalence of Regions with Holes
The basic criteria to identify topological equivalence between two regions
with holes are:
- the same number of holes exists in both scenes;
- corresponding holes in both scenes have the same topological relations
with respect to other holes; and
- corresponding holes in both scenes have the same topological relations
with respect to their generalized region.
