Abstract: Reductions transform binary pictures only by changing some black points to white ones. Topology preservation is a major concern of thinning algorithms that are composed of reductions. For (18,12) binary pictures on the 3D face-centered cubic (FCC) grid, we propose four sufficient conditions for topology-preserving parallel reductions that can change a set of black points simultaneously. The first two conditions examine some configurations of changed points, and they provide methods of verifying that formerly constructed parallel reductions preserve the topology. The further two conditions focus on individual points, directly provide deletion rules of topology-preserving parallel reductions, and make us possible to establish topologically correct parallel thinning algorithms.
