Heng Yang and Luca Carlone, In Perfect Shape: Certifiably Optimal 3D Shape Reconstruction from 2D Landmarks, In IEEE Conf. on Computer Vision and Pattern Recognition (CVPR), 2020. —We present Shape*, the first certifiably optimal non-minimal solver for 3D shape reconstruction from 2D landmarks in a single image, and Shape#, a robust shape reconstruction algorithm that tolerates a large amount of outliers in the 2D measurements. We demonstrate the power of Sums-of-Squares (SOS) relaxations in solving challenging geometric perception.

(Video) Best Paper Award in Robot Vision at ICRA 2020. —A general-purpose robust estimation framework called graduated non-convexity (GNC) that can be applied to any problem where a globally optimal non-minimal solver (e.g. from SDP and SOS relaxations) for the outlier-free case is available. Empirically robust againts 70-80% outliers across applications. As an alternative to RANSAC, GNC robustifies non-minimal solvers, while RANSAC robustifies minimal solvers.
