Algebraic Mesh Quality Metrics [PDF]

SIAM Journal on Scientific Computing, 2001
The author builds a mathematical theory of quality metrics for structured and unstructured meshes. A mesh has elements and nodes. An element quality metric is a scalar function of node positions that measures some geometric property of the element with the given nodes.

Using fuzzy link cost and dynamic choice of link quality metrics to achieve QoS and QoE in wireless mesh networks [PDF]

Journal of Network and Computer Applications, 2011
The growth of multimedia applications and wireless systems requires a new behavior of routing protocols for wireless mesh networks (WMNs). It is necessary to provide not only the minimum requirements for quality of service (QoS), but also to assure the quality of experience (QoE) support for multimedia applications.

Quality Metrics for High Order Meshes: Analysis of the Mechanical Simulation of the Heart Beat

IEEE Transactions on Medical Imaging, 2013
The quality of a computational mesh is an important characteristic for stable and accurate simulations. Quality depends on the regularity of the initial mesh, and in mechanical simulations it evolves in time, with deformations causing changes in volume and distortion of mesh elements.

An Alternating Mesh Quality Metric Scheme for Efficient Mesh Quality Improvement

Procedia Computer Science, 2011
AbstractIn the numerical solution of partial differential equations (PDEs), high-quality meshes are crucial for the stability, accuracy, and convergence of the associated PDE solver. Mesh quality improvement is often performed to improve the quality of meshes before use in numerical solution of the PDE.

A perceptual quality metric for dynamic triangle meshes

EURASIP Journal on Image and Video Processing, 2017
A measure for assessing the quality of a 3D mesh is necessary in order to determine whether an operation on the mesh, such as watermarking or compression, affects the perceived quality. The studies on this field are limited when compared to the studies for 2D.
