Improving Camera Exterior Orientation Estimation using Vanishing Point Detection [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The estimation of camera pose with respect to a known object has been a fundamental challenge since the inception of photogrammetry. This task is crucial for applications ranging from 3D reconstruction to augmented reality.

Consistency between black hole and mimetic gravity – Case of (2 + 1)-dimensional gravity

Physics Letters B, 2022
We show that the mimetic theory with the constraint gρσ∂ρϕ∂σϕ=1 cannot realize the black hole geometry with the horizon(s). To overcome such issue, we may change the mimetic constraint a little bit by ω(ϕ)gρσ∂ρϕ∂σϕ=−1, where ω(ϕ) is a function of the ...

Sign-changing solutions for Schrödinger–Kirchhoff-type fourth-order equation with potential vanishing at infinity

Journal of Inequalities and Applications, 2021
The purpose of this paper is to study the existence of sign-changing solution to the following fourth-order equation: 0.1 Δ 2 u − ( a + b ∫ R N | ∇ u | 2 d x ) Δ u + V ( x ) u = K ( x ) f ( u ) in  R N , $$ \Delta ^{2}u- \biggl(a+ b \int _{\mathbb{R}^{N}}

Comparing matrix models and QCD lattice data with chemical potential [PDF]

, 2003
We present a quantitative analysis of the microscopic Dirac spectrum which is complex in the presence of a non-vanishing quark chemical potential. Data from quenched SU(3) lattice simulations for different volumes V and small values of the chemical ...

On a critical Choquard-type equation with vanishing potential in the Heisenberg group

Electronic Journal of Qualitative Theory of Differential Equations
In this article, we prove the existence of a weak solution to the sub-elliptic problem \begin{align*} \begin{split} -\Delta_{\mathbb{H}} u + V(\xi)u =\left( \int_{\mathbb{H}^N} \frac{|u(\eta)|^{Q^*_{\alpha}} + K(\eta)|u(\eta)|^p}{|\eta^{-
