Shape from Varying Illumination and Viewpoint
We address the problem of reconstructing the 3-D shape of a Lambertian surface from multiple images acquired as an object rotates under distant and possibly varying illumination. From camera projection matrices estimated from point correspondences…

The systematic normal form of lattices, and their algorithmic applications. [joint work with Peter Shor; Lior Eldar]
The systematic normal form of lattices is a new echelon form of lattices in which the entries obey a certain co-primality condition. These lattices can be used to approximate efficiently any lattice, and hence are…
