Holistically-attracted wireframe parsing

N Xue, T Wu, S Bai, F Wang, GS Xia… - Proceedings of the …, 2020 - openaccess.thecvf.com
This paper presents a fast and parsimonious parsing method to accurately and robustly
detect a vectorized wireframe in an input image with a single forward pass. The proposed …

Learning to solve hard minimal problems

P Hruby, T Duff, A Leykin… - Proceedings of the IEEE …, 2022 - openaccess.thecvf.com
We present an approach to solving hard geometric optimization problems in the RANSAC
framework. The hard minimal problems arise from relaxing the original geometric …

Multi-person 3d pose estimation in crowded scenes based on multi-view geometry

H Chen, P Guo, P Li, GH Lee, G Chirikjian - Computer Vision–ECCV 2020 …, 2020 - Springer
Epipolar constraints are at the core of feature matching and depth estimation in current multi-
person multi-camera 3D human pose estimation methods. Despite the satisfactory …

P Breiding, K Kohn, B Sturmfels - 2024 - library.oapen.org
Metric algebraic geometry combines concepts from algebraic geometry and differential
geometry. Building on classical foundations, it offers practical tools for the 21st century …

Theoretical and numerical analysis of 3d reconstruction using point and line incidences

F Rydell, E Shehu, A Torres - Proceedings of the IEEE/CVF …, 2023 - openaccess.thecvf.com
We study the joint image of lines incident to points, meaning the set of image tuples obtained
from fixed cameras observing a varying 3D point-line incidence. We prove a formula for the …

Minimal solutions for relative pose with a single affine correspondence

B Guan, J Zhao, Z Li, F Sun… - Proceedings of the …, 2020 - openaccess.thecvf.com
In this paper we present four cases of minimal solutions for two-view relative pose estimation
by exploiting the affine transformation between feature points and we demonstrate efficient …

Minimal solutions to generalized three-view relative pose problem

Y Ding, CH Chien, V Larsson… - Proceedings of the …, 2023 - openaccess.thecvf.com
For a generalized (or non-central) camera model, the minimal problem for two views of six
points has efficient solvers. However, minimal problems of three views with four points and …

Learning selection strategies in Buchberger's algorithm

D Peifer, M Stillman… - … on Machine Learning, 2020 - proceedings.mlr.press
Studying the set of exact solutions of a system of polynomial equations largely depends on a
single iterative algorithm, known as Buchberger's algorithm. Optimized versions of this …
