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

Matrix geometries emergent from a point [PDF]
Reviews in Mathematical Physics, 2014 We describe a categorical approach to finite noncommutative geometries. Objects in the category are spectral triples, rather than unitary equivalence classes as in other approaches. This enables us to treat fluctuations of the metric and unitary equivalences on the same footing, as representatives of particular morphisms in this category. We then show

Learning Geometry-Disentangled Representation for Complementary Understanding of 3D Object Point Cloud [PDF]
AAAI Conference on Artificial Intelligence, 2020 In 2D image processing, some attempts decompose images into high and low frequency components for describing edge and smooth parts respectively. Similarly, the contour and flat area of 3D objects, such as the boundary and seat area of a chair, describe ...

The influence of drill point geometry on tool life
Tehnički Glasnik, 2018 Drilling is a cutting process that uses a rotary cutting tool to cut a cylindrical hole in a solid material. During machining, drill bits are exposed to rapid wear at high temperature.

Emergent unitarity, all-loop cuts and integrations from the ABJM amplituhedron
Journal of High Energy Physics, 2023 We elaborate on aspects of a new positive geometry proposed recently, which was conjectured to be the four-point amplituhedron for ABJM theory. We study generalized unitarity cuts from the geometry, and in particular we prove that (1) the four-point ...

A point's point of view of stringy geometry [PDF]
Journal of High Energy Physics, 2003 The notion of a "point" is essential to describe the topology of spacetime. Despite this, a point probably does not play a particularly distinguished role in any intrinsic formulation of string theory. We discuss one way to try to determine the notion of a point from a worldsheet point of view.

Categorical Geometry and Integration Without Points [PDF]
Applied Categorical Structures, 2012 The theory of integration over infinite-dimensional spaces is known to encounter serious difficulties. Categorical ideas seem to arise naturally on the path to a remedy. Such an approach was suggested and initiated by Segal in his pioneering article \cite{segal}.

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.
