Title:

Projective Geometry for Computer Vision

Abstract:

Projective geometry has been shown in recent years to offer a new set of approaches to the classical computer vision problem of recovering a 3D model of camera and scene point locations from uncalibrated image collections. This talk will start with a brief introduction to projective models of multiple view camera geometry. We then address the challenge of estimating many interacting camera parameters under unknown imaging conditions via a new projective parameterization for view triplets that enforces dependencies among camera pairs. This model is shown to guarantee a geometrically consistent camera configuration and improve the estimated camera configuration for image pairs with poor view overlap using the estimated relations between cameras with high view overlap. We end with a discussion of two practical applications of projective models: motion boundary detection and novel view synthesis.
