Globally Optimal Algorithms for Affine and Metric Upgrades in Stratified Autocalibration [ www ] [ pdf] WebOptimization using the L ∞ norm is an increasingly important area in multiview geometry. Previous work has shown that globally optimal solutions can be computed reliably using the formulation of generalized fractional programming, in which algorithms solve a sequence of convex problems independently to approximate the optimal L ∞ norm error.
