A surface \(S\) is a closed 2-manifold, either orientable \((S_p\), of genus \(p\geq 0)\) or nonorientable \((N_p\), of genus \(p>0\)). A clean triangulation of \(S\) is a 2-cell imbedding of a graph \(G\) into \(S\) having every 2-cell bounded by a 3-cycle of \(G\) and having every 3-cycle of \(G\) bound a 2-cell. Then \(\tau(S)\) denotes the smallest

Computer Vision and Image Understanding, 2009
This article presents a computationally efficient approach to the triangulation of 3D points from their projections in two views. The homogenous coordinates of a 3D point is given as a multi-linear mapping on its homogeneous image coordinates, a computation of low computational complexity.

Composite structures, 2019
The triangulation method has been an effective tool for estimating the source locations of various acoustic emissions (AE). However, it is hard to guarantee high accuracy in composite structures due to their anisotropy.

We analyze several perfect-information combinatorial games played on planar triangulations. We introduce three broad categories of such games: constructing, transforming, and marking triangulations. In various situations, we develop polynomial-time algorithms to determine who wins a given game under optimal play, and to find a winning strategy.

Combinatories and Triangulations
2004The problem searching for an optimal triangulation with required properties (in a plane) is solved in this paper. Existing approaches are shortly introduced here and, specially, this paper is dedicated to the brute force methods. Several new brute force methods that solve the problem from different points of view are described here.

We introduce the notion of harmonic triangulations: a harmonic triangulation simultaneously minimizes the Dirichlet energy of all piecewise linear functions. By a famous result of Rippa, Delaunay triangulations are the harmonic triangulations of planar point sets. We prove by explicit counterexample that in 3D a harmonic triangulation does not exist in
