A study of horizontally weakly conformal maps and their distributions [PDF]

open access: yesریاضی و جامعه, 2023
The aim of this paper is to consider horizontally weakly conformal maps which have been studied in [P. Baird and J. C. Wood, Harmonic morphisms between Riemannian manifolds, London Mathematical Society Monographs.

Geometry of Fisher Information Metric and the Barycenter Map

open access: yesEntropy, 2015
Geometry of Fisher metric and geodesics on a space of probability measures defined on a compact manifold is discussed and is applied to geometry of a barycenter map associated with Busemann function on an Hadamard manifold \(X\).

Geodesic Mappings and Einstein Spaces [PDF]

open access: yes, 2012
In this paper we study fundamental properties of geodesic mappings with respect to the smoothness class of metrics. We show that geodesic mappings preserve the smoothness class of metrics. We study geodesic mappings of Einstein spaces.

A FUZZY AUTOMATIC CAR DETECTION METHOD BASED ON HIGH RESOLUTION SATELLITE IMAGERY AND GEODESIC MORPHOLOGY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Automatic car detection and recognition from aerial and satellite images is mostly practiced for the purpose of easy and fast traffic monitoring in cities and rural areas where direct approaches are proved to be costly and inefficient.

Merge Tree Geodesics and Barycenters with Path Mappings

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2023
Comparative visualization of scalar fields is often facilitated using similarity measures such as edit distances. In this paper, we describe a novel approach for similarity analysis of scalar fields that combines two recently introduced techniques: Wasserstein geodesics/barycenters as well as path mappings, a branch decomposition-independent edit ...

Skinning maps [PDF]

open access: yes, 2009
Let M be a hyperbolic 3-manifold with nonempty totally geodesic boundary. We prove that there are upper and lower bounds on the diameter of the skinning map of M that depend only on the volume of the hyperbolic structure with totally geodesic boundary ...

An adaptive Markov chain algorithm applied over map-matching of vehicle trip GPS data

open access: yesGeo-spatial Information Science, 2021
Markov chains have frequently been applied to match the probable routes with a set of GPS trip data that a pilot vehicle is emitting over a specific graph road network.

Part-to-full shape matching of different human subjects

open access: yesHeliyon, 2021
Shape matching is a fundamental operation in digital geometry processing and computer graphics. Challenges in shape matching include finding correspondences of partial shapes with deformations, as well as topological noise and ambiguities.

Development of Multilayer-Based Map Matching to Enhance Performance in Large Truck Fleet Dispatching

open access: yesISPRS International Journal of Geo-Information, 2021
Spatial information technology has been widely used for vehicles in general and for fleet management. Many studies have focused on improving vehicle positioning accuracy, although few studies have focused on efficiency improvements for managing large ...

Geodesic Mapping for Dynamic Surface Alignment [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2014
This paper presents a novel approach that achieves dynamic surface alignment by geodesing mapping. The surfaces are 3D manifold meshes representing non-rigid objects in motion (e.g., humans) which can be obtained by multiview stereo reconstruction. The proposed framework consists of a geodesic mapping (i.e., geodesic diffeomorphism) between surfaces ...
