Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On a Bogomolov type vanishing theorem
Bogomolov型 消失定理 代数几何
2023/11/29
The Bogomolv theorem holds great importance in algebraic geometry, particularly in the field of birational geometry. During this presentation, we will introduce our recent work on a variant of the Bog...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Remarks on the vanishing viscosity process of state-constraint Hamilton-Jacobi equations
状态约束 哈密尔顿-雅可比方程 黏度消失
2023/4/21
We investigate the convergence rate in the vanishing viscosity process of the solutions to the subquadratic state-constraint Hamilton-Jacobi equations. We give two different proofs of the fact that, f...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Vanishing of some algebraic cycles on powers of Shimura curves
志村曲线 幂 代数 循环消失
2023/4/27
For a smooth projective variety over a number field, the Beilinson—Bloch conjecture predicts that Chow groups of algebraic cycles modulo rational equivalence can be determined using cohomological data...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The algebraic incarnations of the Artin Vanishing

2023/5/16
The non-abelian Hodge theory, briefly can be viewed as building a correspondence between certain topological objects, analytic objects, and algebraic objects. In this talk, I will show that Kodaira-ty...

Geochemists solve mystery Earth vanishing crust
2020/7/10
Earth's crust is the solid, outermost layer of our planet. Much of what happens below that layer remains a mystery, including the fate of sections of crust that vanish back into the Earth.Now, a team ...
EXTERIOR ORIENTATION ESTIMATION OF OBLIQUE AERIAL IMAGERY USING VANISHING POINTS
Oblique Aerial Images Vanishing Point Nadir Point True Horizon Line Exterior Orientation Georeferencing
2016/7/27
In this paper, a methodology for the calculation of rough exterior orientation (EO) parameters of multiple large-scale overlapping oblique aerial images, in the case that GPS/INS information is not av...
Robust and Automatic Vanishing Points Detection with Their Uncertainties from a Single Uncalibrated Image, by Planes Extraction on the Unit Sphere
Photogrammetry Geometry Vanishing points extraction Image Orientation Error estimation
2015/12/4
This paper deals with the retrieval of vanishing points in uncalibrated images. Many authors did work on that subject in the computer vision field because the vanishing point represents a major inform...
EXTRACTION OF HORIZONTAL VANISHING LINE USING SHAPES AND STATISTICAL ERROR PROPAGATION

A unified approach for automatic camera calibration from vanishing points
Automation Calibration Distortion Edge Extraction
2015/8/25
A novel approach is presented for automatic camera calibration from single images with three finite vanishing points in mutually or thogonal directions (or of more independent images having two and/or...
A NEW METHOD FOR VANISHING POINTS DETECTION IN 3D RECONSTRUCTION FROM A SINGLE VIEW
Photogrammetry 3D reconstruction Single-Image Technique Geometry vanishing points estimation
2015/8/7
From a single view that contains a three dimensional scene is possible to obtain substantial information about the object and even its
partial reconstruction. This analysis can provide, in the case ...

Camera Calibration Combining Images With Two Vanishing Points
Calibration Geometry Distortion
2015/7/14
Single image calibration is a fundamental task in photogrammetry and computer vision. It is known that camera constant and principal
point can be recovered using exclusively the vanishing points of t...
