Computer Vision studies image formation in cameras. In particular, we consider the reconstruction problem: Given images in several cameras of the same scene, triangulate the scene, i.e. find the camera locations and the preimages in the world. There is an algebraic part of this theory that ignores the question whether the reconstruction consists of points that are in front of the camera. We address this issue. This involves semi-algebraic geometry, which we discuss in a projective setup.
This is joint work with Sameer Agarwal, Andrew Pryhuber, and Rekha Thomas.
