Structure-aware Building Mesh Polygonization
ISPRS Journal of Photogrammetry and Remote Sensing, 2020 We introduce a novel approach for the polygonization of Multi-view Stereo (MVS) meshes of buildings, which results in compact and topologically valid models. The main characteristic of our method is structure awareness, i.e., the recovery and preservation of the initial mesh primitives and their adjacencies.

A steganalytic algorithm for 3D polygonal meshes [PDF]
2014 IEEE International Conference on Image Processing (ICIP), 2014 We propose a steganalytic algorithm for watermarks embedded by Cho et al.'s mean-based algorithm [1]. The main observation is that while in a clean model the means of Cho et al.'s normalized histogram bins are expected to follow a Gaussian distribution, in a marked model their distribution will be bimodal. The proposed algorithm estimates the number of

Modeling the spatiotemporal variability in subsurface thermal regimes across a low-relief polygonal tundra landscape [PDF]
The Cryosphere, 2016 Vast carbon stocks stored in permafrost soils of Arctic tundra are under risk of release to the atmosphere under warming climate scenarios. Ice-wedge polygons in the low-gradient polygonal tundra create a complex mosaic of microtopographic features ...

Online access and sharing of reality-based 3d models
SCIRES-IT, 2014 The article presents an investigation on techniques and solutions for publishing reality-based 3D models online. The process starts from a dense point cloud and leads to a reduced textured 3D model accessible on the web with a browser.

Penalty Virtual Element Method for the 3D Incompressible Flow on Polyhedron Mesh
Entropy, 2022 In this paper, a penalty virtual element method (VEM) on polyhedral mesh for solving the 3D incompressible flow is proposed and analyzed. The remarkable feature of VEM is that it does not require an explicit computation of the trial and test space ...

Surface classification on a 3D cardiac ventricular model using machine learning
Компьютерная оптикаThis work improves techniques for the classification of cardiac ventricular surfaces on a polygonal surface mesh in the context of small datasets. This task is reduced to a multi-class classification of a point on a surface mesh.
