A Geometry Feature Aggregation Method for Point Cloud Classification and Segmentation
IEEE Access, 2021 In spite of the good performance of convolutional neural network (CNN) and graph neural network (GNN) in 3D point cloud classification and segmentation at present, to aggregate local information of point clouds and improve the robustness of geometric ...

On transparent embeddings of point-line geometries [PDF]
Journal of Combinatorial Theory, Series A, 2018 We introduce the class of transparent embeddings for a point-line geometry $ = ({\mathcal P},{\mathcal L})$ as the class of full projective embeddings $\varepsilon$ of $ $ such that the preimage of any projective line fully contained in $\varepsilon({\mathcal P})$ is a line of $ $.

Non-perturbative Gauge Groups and Local Mirror Symmetry [PDF]
, 2001 We analyze D-brane states and their central charges on the resolution of C^2/Z_n by using local mirror symmetry. There is a point in the moduli space where all n(n-1)/2 branches of the principal component of the discriminant locus coincide. We argue that

OpenCRG Models From Different Data Sources to Support Vehicle Simulations
IEEE Access, 2022 Digital twins of road surfaces support multiple engineering applications. Remote sensing technologies provide information from the entire surface of the pavement by high accuracy point clouds. Pavement errors and differences from designed geometry can be

IEEE Access, 2020 Since lane geometry information can be used for controlling the pose of an intelligent vehicle, a lane geometry map that contains the lane geometry information should have reliable accuracy. For generating the reliable lane geometry map, lane curve which

The horofunction boundary of the Hilbert geometry [PDF]
Advances in Geometry, 8 (4) 503-529, 2008, 2006 We investigate the horofunction boundary of the Hilbert geometry defined on an arbitrary finite-dimensional bounded convex domain D. We determine its set of Busemann points, which are those points that are the limits of `almost-geodesics'. In addition, we show that any sequence of points converging to a point in the horofunction boundary also converges

Statistical Properties of Strain and Rotation Tensors in Geodetic Network [PDF]
, 2010 This article deals with the characteristics of deformation of a body or a figure represented by discrete points of geodetic network. In each point of geodetic network kinematic quantities are considered normal strain, shear strain, and rotation. They are

Shape modeling with point-sampled geometry [PDF]
ACM Transactions on Graphics, 2003 We present a versatile and complete free-form shape modeling framework for point-sampled geometry. By combining unstructured point clouds with the implicit surface definition of the moving least squares approximation, we obtain a hybrid geometry representation that allows us to exploit the advantages of implicit and parametric surface models.

Cosmological evolution and dark energy in osculating Barthel–Randers geometry
European Physical Journal C: Particles and Fields, 2021 We consider the cosmological evolution in an osculating point Barthel–Randers type geometry, in which to each point of the space-time manifold an arbitrary point vector field is associated.

Hamilton Geometry - Phase Space Geometry from Modified Dispersion Relations
, 2018 Quantum gravity phenomenology suggests an effective modification of the general relativistic dispersion relation of freely falling point particles caused by an underlying theory of quantum gravity. Here we analyse the consequences of modifications of the
