Kong, T.Y., A.W. Roscoe and A. Rosenfeld, Concepts of digital topology, Topology and its Applications 46 (1992) 219-262. In an earlier paper written for a different readership [Computers and Graphics 13(2) (1989) 159-1661 the first author defined a digitalfundamentalgroup-an analog, for binary digital pictures, of the fundamental group. In general the definition of the digital fundamental group involves continuous deformation. But an alternative, discrete, definition of the digital fundamental group was proposed for the strongly normal digital picture spaces defined in the same paper. The above-mentioned paper also defined a “continuous analog” C(p) for each binary digital picture B on such a DPS (DPS = digital picture space). C(p) is a polyhedron constructed by “filling in the gaps” between black points (l’s) of the binary digital picture B in a specific way. Other kinds of continuous analog had previously been used by the first two authors. In seeking the simplest and most efficient algorithms for performing image processing operations, researchers have considered many different combinations of grids and adjacency relations. Almost all of those combinations are isomorphic to special cases of the concept of a strongly normal DPS.
