Geometric Algebra: a framework for computing point and line correspondences and projective structure using n uncalibrated cameras
Proceedings of the International Conference on Pattern Recognition (ICPR '96), Vienna.

Abstract: In this paper we present geometric algebra as a system for analysing the geometry of multiple-view images. The power of this approach is illustrated by giving purely geometric derivations of the constraints for point and line correspondences in n-views and via a discussion of projective structure.
