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 …

A polyhedral homotopy algorithm for real zeros

AA Ergür, T Wolff - Arnold Mathematical Journal, 2023 - Springer
We design a homotopy continuation algorithm, that is based on Viro's patchworking method,
for finding real zeros of sparse polynomial systems. The algorithm is targeted for polynomial …

The average condition number of most tensor rank decomposition problems is infinite

C Beltrán, P Breiding, N Vannieuwenhoven - Foundations of …, 2023 - Springer
The tensor rank decomposition, or canonical polyadic decomposition, is the decomposition
of a tensor into a sum of rank-1 tensors. The condition number of the tensor rank …
