BIM RECONSTRUCTION: AUTOMATED PROCEDURAL MODELING FROM POINT CLOUD DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
The reconstruction of Building Information Modeling objects for as-built modeling is currently the subject of ongoing research. A popular method is to extract structure information from point cloud data to create a set of parametric objects.

A Texture Integrated Deep Neural Network for Semantic Segmentation of Urban Meshes

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
3-D geo-information is essential for many urban related applications. Point cloud and mesh are two common representations of the 3-D urban surface. Compared to point cloud data, mesh possesses indispensable advantages, such as high-resolution image ...

Particle physics from the noncommutative geometry point of view [PDF]

open access: yes, 1993
Recent development in noncommutative geometry generalization of gauge theory is reviewed. The mathematical apparatus is reduced to minimum in order to allow the non-mathematically oriented physicists to follow the development in the interesting field of ...

A characterization of hyperbolic geometry among Hilbert geometry [PDF]

open access: yesJ. Geom. 89 (2008), no. 1-2, 48--52., 2007
In this paper we characterize hyperbolic geometry among Hilbert geometry by the property that three medians of any hyperbolic triangle all pass through one point.

Advanced Patch-Based Affine Motion Estimation for Dynamic Point Cloud Geometry Compression

open access: yesSensors
The substantial data volume within dynamic point clouds representing three-dimensional moving entities necessitates advancements in compression techniques. Motion estimation (ME) is crucial for reducing point cloud temporal redundancy.

A Generalization of Certain Remarkable Points of the Triangle Geometry [PDF]

open access: yesarXiv, 2010
In this article we prove a theorem that will generalize the concurrence theorems that are leading to the Franke's point, Kariya's point, and to other remarkable points from the triangle geometry.

Automatic normal orientation in point clouds of building interiors

open access: yes, 2019
Orienting surface normals correctly and consistently is a fundamental problem in geometry processing. Applications such as visualization, feature detection, and geometry reconstruction often rely on the availability of correctly oriented normals.

Point derivation of partial geometries

open access: yesEuropean Journal of Combinatorics, 2003
AbstractWe introduce a new construction method for semipartial geometries, called point derivation, which is a generalization of the known theory of constructing partial quadrangles from generalized quadrangles.

On the geometry of Hermitian one-point codes

open access: yesJournal of Algebra, 2014
In this paper we study the algebraic-geometry of any one-point code on the Hermitian curve. Moreover, we characterize the minimum-weight codewords of some of their dual codes and describe many their small-weight codewords.
