When Two Cameras Meet a Cubic Surface - SIAM SAGA Seminar

Explore a 57-minute seminar from the Society for Industrial and Applied Mathematics featuring Rekha Thomas from the University of Washington. Delve into the fascinating topic "When Two Cameras Meet a Cubic Surface" as part of the Seminar on Applied Geometry and Algebra series. Discover how the multiview variety models images captured by pinhole cameras and learn about the semialgebraic subset arising from physical camera limitations. Examine the minimal problem for a pair of cameras using 5 point pairs and uncover how a cubic surface with 27 real lines carries the combinatorics and arithmetic information of this scenario. Gain insights from this joint work with Sameer Agarwal, Andrew Pryhuber, and Rainer Sinn, moderated by Kathlén Kohn from KTH Royal Institute of Technology.
