Summary:Presents a formulation for recursive recovery of motion, pointwise
structure, and focal length from feature correspondences tracked through
an image sequence. In addition to adding focal length to the state
vector, several representational improvements are made over earlier
structure from motion formulations, yielding a stable and accurate
estimation framework which applies uniformly to both true perspective
and orthographic projection. Results on synthetic and real imagery
illustrate the performance of the estimator
