On a class of point-reflection geometries
Discrete Mathematics, 1994 In [\textit{C. F. Manara} and the second author, Rend. Sci. Mat. Appl. A 125, No. 2, 203-217 (1991; Zbl 0798.51017)] an axiomatic approach to point-reflection geometries has been given (generalizing the case of Euclidean planes where each point is the centre of a unique reflection).

EQUILATERAL POINT SETS IN ELLIPTIC GEOMETRY [PDF]
Indagationes Mathematicae (Proceedings), 1991 This chapter highlights equilateral point sets in elliptic geometry. Elliptic space of r−1 dimensions E r−1 is obtained from r -dimensional vector space R r with inner product ( a , b ). For 1 , any k -dimensional linear subspace R k of R r is called a ( k−1 )-dimensional elliptic subspace E k−1 .

Differential geometry of a surface at a planar point [PDF]
Transactions of the American Mathematical Society, 1936 We shall say that a point 0 of a surface S is a planar point of the third order if the surface has a tangent plane at 0 and if every curve on the surface through 0 has an inflexiont at 0. It is the purpose of this paper to study the surface S in the neighborhood of such a planar point from a projective point of view by making use of the osculantst of ...

Missing the point in noncommutative geometry [PDF]
Synthese, 2021 AbstractNoncommutative geometries generalize standard smooth geometries, parametrizing the noncommutativity of dimensions with a fundamental quantity with the dimensions of area. The question arises then of whether the concept of a region smaller than the scale—and ultimately the concept of a point—makes sense in such a theory.

Absolute Embeddings of Point–Line Geometries
Journal of Algebra, 2001 The paper concerns the existence of absolute embeddings \(e\) of point-line geometries \(\Gamma=({\mathcal P},{\mathcal L})\), that is, any embedding of \(\Gamma\) in some projective space can be derived from \(e\) by projecting onto suitable quotient spaces.

Iterative Geometry Encoding Volume for Stereo Matching [PDF]
Computer Vision and Pattern Recognition, 2023 Recurrent All-Pairs Field Transforms (RAFT) has shown great potentials in matching tasks. However, all-pairs correlations lack non-local geometry knowledge and have difficulties tackling local ambiguities in ill-posed regions.

Sparse Tensor-Based Multiscale Representation for Point Cloud Geometry Compression [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2021 This study develops a unified Point Cloud Geometry (PCG) compression method through the processing of multiscale sparse tensor-based voxelized PCG. We call this compression method SparsePCGC.

TransPCGC: Point Cloud Geometry Compression Based on Transformers
Algorithms, 2023 Due to the often substantial size of the real-world point cloud data, efficient transmission and storage have become critical concerns. Point cloud compression plays a decisive role in addressing these challenges.
