The Problem
Consider multiple views of a scene, for example, in a video. These
amount to central projections onto the retina of an eye or the film of
a camera. The problem is, given this information, to derive models of
the scene in view (which could, in general, be changing). Models can
be a wide variety of things and they are generally purposive or
teleological. However, for the purpose of explaining this work,
consider a model as consisting of the three-dimensional locations of
each scene feature or point, in some coordinate system. In the case of
a changing scene, add to this model the three-dimensional velocity of
moving scene points.
