Image Reconstruction and Chirality in Computer Vision

We first discuss image formation in computer vision (modelling pinhole cameras as projections in projective space) and the associated (complex) algebraic descriptions. The reverse problem is called scene reconstruction which is our second topic. Along the way, we will see real algebraic refinements of the established complex algebraic picture capturing that the constraints that images are taken of an actual three-dimensional scene in real projective space and that the scene is in front of each camera.
