On Projection Matrices and their Applications in Computer Vision

Projection matrices from projective spaces ? to ? have long been used in multiple-view geometry to model the perspective projection created by the pin-hole camera. In this work we introduce higher-dimensional mappings ? ?, ? for the representation of various applications in which the world we view is no longer rigid. We also describe the multi-view constraints from these new projection matrices (where ?) and methods for extracting the (non-rigid) structure and motion for each application.
