An Atlas for the Pinhole Camera

no code implementations27 Jun 2022 Sameer Agarwal, Timothy Duff, Max Lieblich, Rekha Thomas

We introduce an atlas of algebro-geometric objects associated with image formation in pinhole cameras.

The Chiral Domain of a Camera Arrangement

no code implementations19 Mar 2020 Sameer Agarwal, Andrew Pryhuber, Rainer Sinn, Rekha R. Thomas

We introduce the chiral domain of an arrangement of cameras $\mathcal{A} = \{A_1,\dots, A_m\}$ which is the subset of $\mathbb{P}^3$ visible in $\mathcal{A}$.

essential) matrix given $m$ point correspondences in two views.

Certifying the Existence of Epipolar Matrices

no code implementations21 Jul 2014 Sameer Agarwal, Hon-Leung Lee, Bernd Sturmfels, Rekha R. Thomas

Given a set of point correspondences in two images, the existence of a fundamental matrix is a necessary condition for the points to be the images of a 3-dimensional scene imaged with two pinhole cameras.
