The geodesic Fréchet distance between two curves bounding a simple polygon

open access: yesJournal of Computational Geometry
The Fréchet distance is a popular similarity measure that is well understood for polygonal curves in $\mathbb{R}^d$: near-quadratic time algorithms exist, and conditional lower bounds suggest that these results cannot be improved significantly, even in ...

Glued Near Polygons

open access: yesEuropean Journal of Combinatorics, 2001
A partial linear space \((P,L)\) \((P\) set points, \(L\) set of lines) is called a near polygon if the diameter of its point graph is finite and if for every pair \((p,l)\in P\times L\) there is a unique point \(q\in P\) on \(l\) nearest to \(p\) with respect to the natural distance defined on the graph.

Combinatorial Construction of Some Near Polygons

open access: yesJournal of Combinatorial Theory, Series A, 1997
A near \(2n\)-gon is a linear incidence system \((P,L)\) satisfying: (i) every line contains at least two points, (ii) the point graph of \((P,L)\) is connected with diameter \(n\), (iii) for each point line pair \((p,l)\), there is a unique point \(q\) on \(l\) nearest \(p\). Note that near 4-gon is the same thing as a generalized quadrangle.

The Regular Near Polygons of Order (s, 2) [PDF]

open access: yesJournal of Algebraic Combinatorics, 2004
A near polygon is a partial linear space \({\mathcal S}=({\mathcal P},{\mathcal L})\) with the property that for every point \(p\in {\mathcal P}\) and for every line \(L\in {\mathcal L}\) there exists a unique point on \(L\) nearest to \(p\). Here distances \(d\) are measured in the collinearity graph \(\Gamma\). If \(n=\text{ diam}(\Gamma)\), then \({\

Let’s Go Bananas: Beyond Bounding Box Representations for Fisheye Camera-Based Object Detection in Autonomous Driving

open access: yesSensors
Object detection is a mature problem in autonomous driving, with pedestrian detection being one of the first commercially deployed algorithms. It has been extensively studied in the literature.

3D MODELING OF HISTORICAL DOGER CARAVANSARIES BY DIGITAL PHOTOGRAMMETRY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Caravansaries are sort of bigger khan that established on the busy trade roads to provide any kind of supplies but essentially all Caravansaries on Anatolia are established for caravans' accommodations which are passing through on caravan rout.

Numerical analysis to estimate near-wellbore drilling induced failures area for fractured formation using Universal Discrete Element Codes (UDEC)

open access: yesCogent Engineering, 2021
There have been reported cases of wellbore instability near-wellbore area due to failures associated with drilling operations, the magnitude and extension of the failure area is imprecisely evaluated by copious researchers due to some of the limitations ...
