                         Recovery of Epipolar Geometry
                         as a Manifold Fitting Problem

The introduction of the joint image manifold allows to treat the problem of 
recovering camera motion and epipolar geometry as a problem of fitting the 
manifold to the data measured in a stereo pair. The manifold has a singularity, 
therefore care must be taken when fitting it.

I will review the notion of joint image manifold, and how previous motion recovery
methods can be viewed in its context, and then offer a new fitting method, which
improves upon previous results, especially when the extent of the data and/or the
motion are small.

Joint work with P. Anandan (Microsoft), and I. Shimshoni, L. Goshen (Technion).
