Photometric Stereo

Photometric Stereo is a common method to acquire the shape of objects. We seek to extend the technique to non-Lambertian Reflectance, use differential methods to develop a new framework, and unify photometric stereo with shape from shading and structure from motion within the differential framework...

Globally Optimal Structure and Motion Estimation

In this line of work, we persent globally optimal solutions to several important problems in multiview geometry. Structure from motion problems are inherently non-convex and these works rely on efficient construction of relaxations using developments in convex optimization and algebraic geometry.
