Multiple View Relations Using the Teaching and Learning-Based Optimization Algorithm

open access: yesComputers, 2020
In computer vision, estimating geometric relations between two different views of the same scene has great importance due to its applications in 3D reconstruction, object recognition and digitization, image registration, pose retrieval, visual tracking ...

The Tracial Hahn-Banach Theorem, Polar Duals, Matrix Convex Sets, and Projections of Free Spectrahedra [PDF]

open access: yes, 2016
This article investigates matrix convex sets and introduces their tracial analogs which we call contractively tracial convex sets. In both contexts completely positive (cp) maps play a central role: unital cp maps in the case of matrix convex sets and ...

A fast monocular visual odometry pose estimation method for self-driving vehicles

open access: yesJournal of Hebei University of Science and Technology, 2017
Aiming at the problem that the traditional pose estimation algorithm of monocular odometry cannot meet the needs of real-time localization of self-driving vehicles, a fast pose estimation algorithm based on the improvement of the fundamental matrix is ...

Adding flavor to Dijkgraaf-Vafa [PDF]

open access: yes, 2002
We study matrix models related via the correspondence of Dijkgraaf and Vafa to supersymmetric gauge theories with matter in the fundamental. As in flavorless examples, measure factors of the matrix integral reproduce information about R-symmetry ...

Radial Distortion from Epipolar Constraint for Rectilinear Cameras

open access: yesJournal of Imaging, 2017
Lens distortion causes difficulties for 3D reconstruction, when uncalibrated image sets with weak geometry are used. We show that the largest part of lens distortion, known as the radial distortion, can be estimated along with the center of distortion ...

On the fundamental solutions-based inversion of Laplace matrices

open access: yesResults in Applied Mathematics, 2022
The discretisation of the Laplacian results into the well-known Laplace matrix. In the case of a one dimensional problem, an explicit formula for its inverse is derived on the basis of fundamental solutions (Green’s functions) for general boundary ...

The Sine-Gordon Solitons as a N-Body Problem

open access: yes, 1993
We consider the N-soliton solutions in the sine-Gordon model as a N-body problem. This leads to a relativistic generalization of the Calogero model first introduced by Ruijsenaars.
