Combinatorial boundary of a 3D lattice point set
Boundary extraction and surface generation are important topological topics for threedimensional digital image analysis. However, there is no adequate theory to establish relations between these different topological procedures in a completely discrete way. In this paper, we present a new boundary extraction algorithm which gives not only a set of border points but also a polyhedral surface who...

Boundary tracking and surface generation are ones of main topological topics for threedimensional digital image analysis. However, there is no adequate theory to make relations between these different topological properties in a completely discrete way, In this paper, we present a new boundary tracking algorithm which gives not only a set of border points but also the surface structures by usin...
متن کاملLattice Point Methods for Combinatorial Games
We encode arbitrary finite impartial combinatorial games in terms of lattice points in rational convex polyhedra. Encodings provided by these lattice games can be made particularly efficient for octal games, which we generalize to squarefree games. These additionally encompass all heap games in a natural setting, in which the Sprague–Grundy theorem for normal play manifests itself geometrically...
متن کاملA convex combinatorial property of compact sets in the plane and its roots in lattice theory
K. Adaricheva and M. Bolat have recently proved that if $,mathcal U_0$ and $,mathcal U_1$ are circles in a triangle with vertices $A_0,A_1,A_2$, then there exist $jin {0,1,2}$ and $kin{0,1}$ such that $,mathcal U_{1-k}$ is included in the convex hull of $,mathcal U_kcup({A_0,A_1, A_2}setminus{A_j})$. One could say disks instead of circles.Here we prove the existence of such a $j$ and $k$ ...
متن کاملIntroduced a Modified Set of Boundary Condition of Lattice Boltzmann Method Based on Bennett extension in Presence of Buoyancy Term Considering Variable Diffusion Coefficients
Various numerical boundary condition methods have been proposed to simulate various aspects of the no-slip wall condition using the Lattice Boltzmann Method. In this paper, a new boundary condition scheme is developed to model the no-slip wall condition in the presence of the body force term near the wall which is based on the Bennett extension. The error related to the new model is smaller tha...
