Abstract: A 2D topological map allows one to fully describe the topology of a labeled image. In this paper we define 2D topological map isomorphism. We show that isomorphic topological maps correspond to homeomorphic embeddings in the plane and we give a polynomial-time algorithm for deciding of topological map isomorphism. Then we use this notion to give a generic definition of multi-label simple transformation as a set of transformations of labels of pixels which does not modify the topology of the labeled image. We illustrate the interest of multi-label simple transformation by generating look-up tables of any pair of adjacent pixel transformation preserving the topology.

Keywords: Combinatorial maps; 2D topological maps isomorphism; Labeled image; Simple points; Simple sets.
