Abstract
Photometric changes can lead to severe errors in shape recovery if not correctly accounted for. The author shows that photometric motion can be used to obtain a closed-form solution for both surface shape and reflectance and discusses how this solution can be used to enhance the performance of geometrically based structure-from-motion algorithms. A simple biological mechanism is demonstrated that accomplishes the recovery of both shape and reflectance
