High Precision Mesh-Based Drone Image Stitching Based on Salient Structure Preservation and Regular Boundaries

open access: yesDrones, 2023
Addressing problems such as obvious ghost, dislocation, and distortion resulting from the traditional stitching method, a novel drone image-stitching method is proposed using mesh-based local double-feature bundle adjustment and salient structure ...

A mesh optimization method using machine learning technique and variational mesh adaptation

open access: yesChinese Journal of Aeronautics, 2021
Computational mesh is an important ingredient that affects the accuracy and efficiency of CFD numerical simulation. In light of the introduced large amount of computational costs for many adaptive mesh methods, moving mesh methods keep the number of ...

Combinatorial mesh optimization [PDF]

open access: yesThe Visual Computer, 2011
A new mesh optimization framework for 3D triangular surface meshes is presented, which formulates the task as an energy minimization problem in the same spirit as in Hoppe et al. (SIGGRAPH’93: Proceedings of the 20th Annual Conference on Computer Graphics and Interactive Techniques, 1993).

Laplacian mesh optimization [PDF]

open access: yesProceedings of the 4th international conference on Computer graphics and interactive techniques in Australasia and Southeast Asia, 2006
We introduce a framework for triangle shape optimization and feature preserving smoothing of triangular meshes that is guided by the vertex Laplacians, specifically, the uniformly weighted Laplacian and the discrete mean curvature normal. Vertices are relocated so that they approximate prescribed Laplacians and positions in a weighted least-squares ...

Optimal Cache-Oblivious Mesh Layouts [PDF]

open access: yesTheory of Computing Systems, 2009
A mesh is a graph that divides physical space into regularly-shaped regions. Meshes computations form the basis of many applications, e.g. finite-element methods, image rendering, and collision detection. In one important mesh primitive, called a mesh update, each mesh vertex stores a value and repeatedly updates this value based on the values stored ...

Photometric Mesh Optimization for Video-Aligned 3D Object Reconstruction [PDF]

open access: yesComputer Vision and Pattern Recognition, 2019
In this paper, we address the problem of 3D object mesh reconstruction from RGB videos. Our approach combines the best of multi-view geometric and data-driven methods for 3D reconstruction by optimizing object meshes for multi-view photometric ...

Adjoint-Based High-Fidelity Concurrent Aerodynamic Design Optimization of Wind Turbine

open access: yesFluids, 2023
To evaluate novel turbine designs, the wind energy sector extensively depends on computational fluid dynamics (CFD). To use CFD in the design optimization process, where lower-fidelity approaches such as blade element momentum (BEM) are more popular, new

Geometric parameters in the target matrix mesh optimization paradigm

open access: yesPartial 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 ...
