Polygonal approximation of digital planar curves through vertex betweenness
(ElsevierPhiladelphia, 2013-02)
Contour polygonal approximation is usually defined as a set of selected points, which describes a polygon and best represents the original contour. This paper presents a novel graph based approach to compute a polygonal ...
On polygonal fuzzy sets and numbers

Approximating implicit curves on plane and surface triangulations with affine arithmetic
(ElsevierAmsterdam, 2014-05)
We present a spatially and geometrically adaptive method for computing a robust polygonal approximation of an implicit curve defined on a planar region or on a triangulated surface. Our method uses affine arithmetic to ...
Affine properties of convex equal-area polygons
(Springer, 2012-10)
In this paper we discuss some affine properties of convex equal-area polygons, which are convex polygons such that all triangles formed by three consecutive vertices have the same area. Besides being able to approximate ...

Frequency of transverse vibration of regular polygonal plates with a concentric, circular orthotropic patch
(Academic Press Ltd-elsevier Science Ltd, 2000-11-23)
A first order approximation treatment of the case where a repair is made of the central portion of a vibrating isotropic plate of regular polygonal shape using a material of circularly anisotropic constitutive characteristics ...
An exact algorithm for minimizing vertex guards on art galleries

A numerical implementation for the high-order 2D Virtual Element Method in MATLAB
(2021)
We present a numerical implementation for the Virtual Element Method that in-
corporates high order spaces. We include all the required computations in order to assemble the
stiffness and mass matrices, and right hand ...
