1.classical digital topology I Arbitrary adjacencies inZ n , but also in subdomains I Digital topology = couple of adjacencies (Rosenfeld) I Object = Topology + Set I Operations : neighborhoods, border, connectedness and connected components, decomposition into digital layers, simple points 2.cubical cellular topology I cells, adjacent and incident cells, faces and cofaces I signed cells, signed incidence, 3.digital surface topology I surfels, surfel adjacency, surfel neighborhood I surface tracking (normal, fast), contour tracking innD
