Learning-Based Lossless Compression of 3D Point Cloud Geometry [PDF]
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020 This paper presents a learning-based, lossless compression method for static point cloud geometry, based on context-adaptive arithmetic coding. Unlike most existing methods working in the octree domain, our encoder operates in a hybrid mode, mixing ...

Geometry and topology of symmetric point arrangements [PDF]
Linear Algebra and its Applications, 2021 We investigate point arrangements $v_i\in\mathbb R^d,i\in \{1,...,n \}$ with certain prescribed symmetries. The arrangement space of $v$ is the column span of the matrix in which the $v_i$ are the rows. We characterize properties of $v$ in terms of the arrangement space, e.g.

Efficient Large-Scale Point Cloud Geometry Compression
SensorsDue to the significant bandwidth and memory requirements for transmitting and storing large-scale point clouds, considerable progress has been made in recent years in the field of large-scale point cloud geometry compression.

Homogeneous variational problems: a minicourse [PDF]
, 1999 A Finsler geometry may be understood as a homogeneous variational problem, where the Finsler function is the Lagrangian. The extremals in Finsler geometry are curves, but in more general variational problems we might consider extremal submanifolds of ...

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

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

Geometry without topology as a new conception of geometry [PDF]
, 2001 A geometric conception is a method of a geometry construction. The Riemannian geometric conception and a new T-geometric one are considered. T-geometry is built only on the basis of information included in the metric (distance between two points).

Differentiable surface splatting for point-based geometry processing [PDF]
ACM Transactions on Graphics, 2019 We propose Differentiable Surface Splatting (DSS), a high-fidelity differentiable renderer for point clouds. Gradients for point locations and normals are carefully designed to handle discontinuities of the rendering function.

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 $ $.

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
