Quality improvement of surface triangular mesh using a modified Laplacian smoothing approach avoiding intersection. [PDF]

open access: yesPLoS ONE, 2017
We present a systematic procedure to improve the qualities of triangular molecular surface meshes and at the same time preserve the manifoldness. The procedure utilizes an algorithm to remove redundant points having three or four valences and another ...

Approximation Algorithms for Multicoloring Planar Graphs and Powers of Square and Triangular Meshes

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
A multicoloring of a weighted graph G is an assignment of sets of colors to the vertices of G so that two adjacent vertices receive two disjoint sets of colors. A multicoloring problem on G is to find a multicoloring of G.

Polylidar - Polygons From Triangular Meshes [PDF]

open access: yesIEEE Robotics and Automation Letters, 2020
This paper presents Polylidar, an efficient algorithm to extract non-convex polygons from 2D point sets, including interior holes. Plane segmented point clouds can be input into Polylidar to extract their polygonal counterpart, thereby reducing map size and improving visualization.

Fault-Tolerant Partition Resolvability in Mesh Related Networks and Applications

open access: yesIEEE Access, 2022
Fault-tolerance of a system measures its working capability in the presence of faulty components in the system. The fault-tolerant partition dimension of a network computes the least number of subcomponents of network required to distinctively identify ...

Deep Neural Network for 3D Shape Classification Based on Mesh Feature

open access: yesSensors, 2022
Virtual reality, driverless cars, and robotics all make extensive use of 3D shape classification. One of the most popular ways to represent 3D data is with polygonal meshes. In particular, triangular mesh is frequently employed.

Hessian Eigenfunctions for Triangular Mesh Parameterization [PDF]

open access: yesProceedings of the 11th Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, 2016
Hessian Locally Linear Embedding (HLLE) is an algorithm that computes the nullspace of a Hessian functional H for Dimensionality Reduction (DR) of a sampled manifold M. This article presents a variation of classic HLLE for parameterization of 3D triangular meshes.
