Template-based quadrilateral mesh generation from imaging data
(SPRINGER, 2011)
This paper describes a novel template-based meshing approach for generating good quality quadrilateral meshes from 2D digital images. This approach builds upon an existing image-based mesh generation technique called Imeshp, ...
Generating segmented meshes from textured color images
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
This paper presents a new framework for generating triangular meshes from textured color images. The proposed framework combines a texture classification technique, called W-operator, with Imesh, a method originally conceived ...
A 2-D delaunay refinement algorithm using an initial prerefinement from the boundary mesh
(2008-06-01)
An improvement to the quality bidimensional Delaunay mesh generation algorithm, which combines the mesh refinement algorithms strategy of Ruppert and Shewchuk is proposed in this research. The developed technique uses ...
Generating Segmented Quality Meshes from Images
(SPRINGER, 2009)
Techniques devoted to generating triangular meshes from intensity images either take as input a segmented image or generate a mesh without distinguishing individual structures contained in the image. These facts may cause ...
Free tools and strategies for the generation of 3D finite element meshes: Modeling of the cardiac structures
(2013-06-11)
The Finite Element Method is a well-known technique, being extensively applied in different areas. Studies using the Finite Element Method (FEM) are targeted to improve cardiac ablation procedures. For such simulations, ...
All hexahedral element meshing: Generation of the dual mesh by recurrent subdivision
(Elsevier Science Sa, 2000-02)
The domain geometry is defined by means of a closed all-quadrilateral mesh. The outer mesh imposes very strong restrictions on the possible connectivities between the inner hexahedral elements. Following the guidelines of ...
POLYLLA: polygonal meshing algorithm based on terminal-edge regions
(Springer, 2022)
This paper presents an algorithm to generate a new kind of polygonal mesh obtained from triangulations. Each polygon is built from a terminal-edge region surrounded by edges that are not the longest-edge of any of the two ...
A CPU–GPU framework for optimizing the quality of large meshes
(Elsevier, 2013-03)
The automatic generation of 3D finite element meshes (FEM) is still a bottle neck for the simulation of large fluid-dynamic problems. Although today there are several algorithms that can generate good meshes without user ...
Template-based quadrilateral meshing
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Generating quadrilateral meshes is a highly non-trivial task, as design decisions are frequently driven by specific application demands. Automatic techniques can optimize objective quality metrics, such as mesh regularity, ...
