Genetic Algorithm-based Affine Parameter Estimation for Shape Recognition

open access: yesInternational Journal of Advanced Robotic Systems, 2014
Shape recognition is a classically difficult problem because of the affine transformation between two shapes. The current study proposes an affine parameter estimation method for shape recognition based on a genetic algorithm (GA).

Solitons of discrete curve shortening

open access: yes, 2016
For a polygon in Euclidean space we consider a transformation T which is obtained by applying the midpoints polygon construction twice and using an index shift. For a closed polygon this is a curve shortening process. A polygon is called (affine) soliton

On the stability of the $p$-affine isoperimetric inequality

open access: yes, 2013
Employing the affine normal flow, we prove a stability version of the $p$-affine isoperimetric inequality for $p\geq1$ in $\mathbb{R}^2$ in the class of origin-symmetric convex bodies.

The Schwartzman group of an affine transformation

open access: yesJournal of Spectral Theory, 2023
We compute the Schwartzman group associated with an ergodic affine automorphism of a compact connected abelian group given by the composition of an automorphism of the group and a translation by an element in the path component of the identity. We show that the Schwartzman group can be characterized by evaluating the invariant characters of the ...

Affine Tensor Product Model Transformation

open access: yesComplexity, 2018
This paper introduces the novel concept of Affine Tensor Product (TP) Model and the corresponding model transformation algorithm. Affine TP Model is a unique representation of Linear Parameter Varying systems with advantageous properties that makes it ...

2D affine transform parameters by Gaussian elimination with pivoting [PDF]

open access: yesArchives of Civil Engineering
In many geomatics, computer vision, and computer-aided applications, coordinate transformations are needed to transform from one coordinate system to another, especially in geodesy and photogrammetry.

On the Affine Image of a Rational Surface of Revolution

open access: yesMathematics, 2020
We study the properties of the image of a rational surface of revolution under a nonsingular affine mapping. We prove that this image has a notable property, namely that all the affine normal lines, a concept that appears in the context of affine ...

Contrasting the dynamics of elastic and non-elastic deformations across an experimental colloidal Martensitic transition

open access: yes, 2017
We present a framework to segregate the roles of elastic and non-elastic deformations in the examination of real-space experiments of solid-solid Martensitic transitions.
