FEATURE MATCHING OF HISTORICAL IMAGES BASED ON GEOMETRY OF QUADRILATERALS
historical images image orientation feature matching descriptor matching quadrilaterals geometry
2018/6/4
This contribution shows an approach to match historical images from the photo library of the Saxon State and University Library Dresden (SLUB) in the context of a historical three-dimensional city mod...
Conformal Mapping of Circular Quadrilaterals and Weierstrass Elliptic Functions
conformal mapping accessory parameter Schwarzian derivative
2011/2/21
Numerical and theoretical aspects of conformal mappings from a disk to a circular-arc quadrilateral, symmetric with respect to the coordinate axes, are devel-oped.
Degree conditions for the partition of a graph into triangles and quadrilaterals

For two positive integers r and s with r ≥ 2s−2, if G is a graph of order 3r+4s such that d(x)+d(y) ≥ 4r+4s for every xy 6∈ E(G), then G independently contains r triangles and s quadrilaterals, ...
Motivated by some questions in Euclidean Ramsey theory, our aim in this note is to show that there exists a cyclic quadrilateral that does not embed into any transitive set (in any dimension). We show...
Certain Inequalities Concerning Bicentric Quadrilaterals, Hexagons and Octagons
Bicentric Polygon Inequality
2008/7/1
In this paper we restrict ourselves to the case when conics are circles one completely inside of the other. Certain inequalities concerning bicentric quadrilaterals, hexagons and octagons in connectio...

ARE BILINEAR QUADRILATERALS BETTER THAN LINEAR TRIANGLES
linear approximation bilinear quadrilaterals linear triangles finite element computations
2007/3/29
This paper compares the theoretical effectiveness of bilinear approximation over quadrilaterals with linear approximation over triangles. Anisotropic mesh transformation is used to generate asymptotic...
