Learning Graph Convolutional Network for Blind Mesh Visual Quality Assessment

IEEE Access, 2021
This paper proposes a new method for blind mesh visual quality assessment (MVQA) based on a graph convolutional network. For that, we address the node classification problem to predict the perceived visual quality. First, two matrices representing the 3D

Tetrahedral mesh improvement using moving mesh smoothing, lazy searching flips, and RBF surface reconstruction [PDF]

, 2017
Given a tetrahedral mesh and objective functionals measuring the mesh quality which take into account the shape, size, and orientation of the mesh elements, our aim is to improve the mesh quality as much as possible.

Improving Triangle Mesh Quality with SurfaceNets [PDF]

, 2000
Simulation of soft tissue deformation is a critical part of surgical simulation. An important method for this is finite element (FE) analysis. Models for FE analysis are typically derived by extraction of triangular surface meshes from CT or MRI image data.

Geometric parameters in the target matrix mesh optimization paradigm

Partial Differential Equations in Applied Mathematics, 2022
The Target Matrix Optimization Paradigm for improving mesh quality has always had, as its agenda, to create a direct path between application mesh quality requirements and a set of target matrices that can result in an optimal mesh that meets the ...
