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

Hilbert geometries with Riemannian points [PDF]
Annali di Matematica Pura ed Applicata (1923 -), 2019 If a Hilbert geometry of twice differentiable boundary has two quadratic infinitesimal spheres, then the Hilbert geometry is a Cayley–Klein model of the hyperbolic geometry.

Some Concepts of Modern Algebraic Geometry: Point, Ideal and Homomorphism [PDF]
, 1994 Starting from classical algebraic geometry over the complex numbers (as it can be found for example in Griffiths and Harris it was the goal of these lectures to introduce some concepts of the modern point of view in algebraic geometry.

Automatic normal orientation in point clouds of building interiors
, 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.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Sparing pharyngeal constrictor muscles (PCMs) during radiotherapy improves patient‐reported swallowing function. This study aimed to explore the feasibility of integrating knowledge‐based planning (KBP) with multicriteria optimization (MCO) in Eclipse v18.0 to selectively spare PCM, quantify the required trade‐off in prophylactic ...

Point derivation of partial geometries
European 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.

Two Points of the Boundary of Toric Geometry [PDF]
, 2018 This note presents two observations which have in common that they lie at the boundary of toric geometry. The first one because it concerns the deformation of affine toric varieties into non toric germs in order to understand how to avoid some ramification problems arising in the study of local uniformization in positive characteristic, and the second ...

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