Metrics for generalized persistence modules [PDF]

, 2015
We consider the question of defining interleaving metrics on generalized persistence modules over arbitrary preordered sets. Our constructions are functorial, which implies a form of stability for these metrics.

The distance between students’ concept image and quadrilateral object definition based on students’ mathematical ability

Al-Jabar, 2022
Students learn mathematics through practical applications without applying it. Consequently, the concept images and definitions that students offer do not match.

Automated Generation of Geometric Theorems from Images of Diagrams [PDF]

, 2014
We propose an approach to generate geometric theorems from electronic images of diagrams automatically. The approach makes use of techniques of Hough transform to recognize geometric objects and their labels and of numeric verification to mine basic ...

PREPROCESSING AND REGISTRATION OF MINISCOPE-BASED CALCIUM IMAGING OF THE RODENT BRAIN [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Microscopic imaging is central to the brain and cognition studies in animals and often requires advanced image processing. In vivo recordings on awake behaving animals require stabilization of the images as the tissue in the images undergoes non-rigid ...

Image of the Burau Representation at $d$-th Roots of unity

, 2013
We prove that the image of the Full braid group $B_{n+1}$ on $n+1$ strands under the Burau representation, evaluated at a primitive $d$-th root of unity is arithmetic provided $n\geq d$.Comment: To appear in Annals of Mathematics.

Post-Disaster Building Damage Assessment: Multi-Class Object Detection vs. Object Localization and Classification

Remote Sensing
Natural disasters demand swift and accurate impact assessment, yet traditional field-based methods remain prohibitively slow. While semi-automatic techniques leveraging remote sensing and drone imagery have accelerated evaluations, existing datasets ...

Cognitive Description of the Vertical Dimension in Foundation of Space Image Schema, based on Cognitive Semantics [PDF]

̒Ilm-i Zabān
According to the embodied mathematics hypothesis, based on the cognitive linguistics’ concepts, the origin of mathematics is human embodiment, and therefore mathematical Platonism and similar descriptions, which assume the existence of mathematics ...

Segmentation of Foreground Row Trees in Apple Orchard Images Collected by Ground Vehicles [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
This paper proposes a fully automatic method for the segmentation of foreground row trees in industrial apple orchard images. The segmentation is based on analyzing a combination of a depth map constructed by the Marigold diffusion model and a model ...
