文摘

Binary tomography of hexagon shape images built up by triangle pixels is considered. 3 lanewise and 6 (lanewise and orthogonal) projection directions are used. Network flow is providing promising initial populations for the genetic approach. Local change, e.g., guided mutations and compactness operators are used. Various switching components are described in formal way for the 3 projection case. Experiments on various images show the efficiency of our algorithm.
