Point Cloud Geometry Compression Based on Multi-Layer Residual Structure
Entropy, 2022 Point cloud data are extensively used in various applications, such as autonomous driving and augmented reality since it can provide both detailed and realistic depictions of 3D scenes or objects.

Joint Geometry and Color Point Cloud Denoising Based on Graph Wavelets
IEEE Access, 2021 A point cloud is an effective 3D geometrical presentation of data paired with different attributes such as transparency, normal and color of each point. The imperfect acquisition process of a 3D point cloud usually generates a significant amount of noise.

Layered Projection-Based Quality Assessment of 3D Point Clouds
IEEE Access, 2021 Point clouds are subject to various distortions during point cloud processing missions, any of which may lead to quality degradation. Consequently, predicting point cloud quality has attracted a lot of attention. In this paper, a layered projection-based

The geometry of degenerations of Hilbert schemes of points [PDF]
Journal of Algebraic Geometry, 2020 Given a strict simple degenerationf:X→Cf \colon X\to Cthe first three authors previously constructed a degenerationIX/Cn→CI^n_{X/C} \to Cof the relative degreennHilbert scheme of00-dimensional subschemes. In this paper we investigate the geometry of this degeneration, in particular when the fibre dimension offfis at most22.

Pairwise transitive 2-designs [PDF]
, 2015 We classify the pairwise transitive 2-designs, that is, 2-designs such that a group of automorphisms is transitive on the following five sets of ordered pairs: point-pairs, incident point-block pairs, non-incident point-block pairs, intersecting block ...

Is the electrostatic force between a point charge and a neutral metallic object always attractive? [PDF]
, 2010 We give an example of a geometry in which the electrostatic force between a point charge and a neutral metallic object is repulsive. The example consists of a point charge centered above a thin metallic hemisphere, positioned concave up.

Dynamic Point Cloud Compression Based on Projections, Surface Reconstruction and Video Compression
Sensors, 2021 In this paper we will present a new dynamic point cloud compression based on different projection types and bit depth, combined with the surface reconstruction algorithm and video compression for obtained geometry and texture maps. Texture maps have been

Is there a Jordan geometry underlying quantum physics? [PDF]
, 2008 There have been several propositions for a geometric and essentially non-linear formulation of quantum mechanics. From a purely mathematical point of view, the point of view of Jordan algebra theory might give new strength to such approaches: there is a `

Automatic Geometry Generation from Point Clouds for BIM
Remote Sensing, 2015 The need for better 3D documentation of the built environment has come to the fore in recent years, led primarily by city modelling at the large scale and Building Information Modelling (BIM) at the smaller scale.

Point-Like Structure in Strings and Non-Commutative Geometry [PDF]
, 1996 Dynamics of a free point particle on a multi world-line is presented and shown to reduce to that of a bosonic string theory at the appropriate limit.
