Descripción
In some recent papers we have introduced a notion of continuity in digital spaces which extends the usual notion of digital continuity. Our approach, which uses multivalued maps, provides a better framework to dene topological notions, like retractions, in a far more realistic way than by using just single-valued digitally continuous functions. In particular, we have characterized the deletion of simple points and some well known parallel thinning algorithm as a particular type of retractions, called (N; k)-retractions. In this paper we give a full characterization of the thinning algorithms that can be modeled as (N; k)-retractions. This class agrees, with minor modications, with the class of thinning algorithms satisfying Ronse necessary conditions for preservation of topology.
