Total Differential Photometric Mesh Refinement with Self-Adapted Mesh Denoising

open access: yesPhotonics, 2022
Variational mesh refinement is a crucial step in multiview 3D reconstruction. Existing algorithms either focus on recovering mesh details or focus on suppressing noise. Approaches with consideration of both are lacking.

Mesh refinement [PDF]

open access: yesMathematics of Computation, 1973
We study mesh refinement techniques for first-order hyperbolic equations. A refinement method for use with the leap-frog scheme is defined and its stability established.

Generic Mesh Refinement On GPU [PDF]

open access: yesProceedings of the ACM SIGGRAPH/EUROGRAPHICS conference on Graphics hardware, 2005
International audienceMany recent publications have shown that a large variety of computation involved in computer graphics can be moved from the CPU to the GPU, by a clever use of vertex or fragment shaders.

Adaptive mesh refinement for storm surge [PDF]

open access: yesOcean Modelling, 2014
An approach to utilizing adaptive mesh refinement algorithms for storm surge modeling is proposed. Currently numerical models exist that can resolve the details of coastal regions but are often too costly to be run in an ensemble forecasting framework without significant computing resources.

Adaptive 3D unstructured mesh refinement [PDF]

open access: yesE3S Web of Conferences, 2020
Algorithms for generating three-dimensional detailed computational meshes are considered. The algorithms are based on adaptive refinement of the original coarse meshes describing a 3D object.

Assessment of different parameters used in mesh independence studies in two-phase slug flow simulations

open access: yesMeasurement: Sensors, 2021
The paper deals with the influence of grid refinement on the formation and evolution of slugs in numerical simulations of horizontal two-phase flow. For this, six meshes with increasing refinement were used. For a quantitative comparison of the different

Mesh Segmentation Refinement [PDF]

open access: yesComputer Graphics Forum, 2009
AbstractThis paper proposes a method for refining existing mesh segmentations, employing a novel extension of the active contour approach to meshes. Given a segmentation, produced either by an automatic segmentation method or interactively, our algorithm propagates the segment boundaries to more appropriate locations.

Stable Dynamical Adaptive Mesh Refinement [PDF]

open access: yesJournal of Scientific Computing, 2021
AbstractWe consider accurate and stable interpolation procedures for numerical simulations utilizing time dependent adaptive meshes. The interpolation of numerical solution values between meshes is considered as a transmission problem with respect to the underlying semi-discretized equations, and a theoretical framework using inner product preserving ...

Adaptive Mesh Refinement in Titanium [PDF]

open access: yes19th IEEE International Parallel and Distributed Processing Symposium, 2005
In this paper, we evaluate Titanium's usability as a high-level parallel programming language through a case study, where we implement a subset of Chombo's functionality in Titanium. Chombo is a software package applying the adaptive mesh refinement methodology to numerical partial differential equations at the production level.
