Abstract
This chapter introduces of two basic types of proximities in the study of relationships between sub-complexes in cell complexes, namely, spatial and descriptive proximities. These proximities are useful in clustering and separating subcomplexes in triangulated finite, bounded surface regions such as those found in visual scenes. This chapter introduces a number of connectedness proximities useful in probing, analyzing, comparing and classifying cell complexes on triangulated surface regions.
