ShapeFit and ShapeKick for Robust, Scalable Structure from Motion [article]

Thomas Goldstein, Paul Hand, Choongbum Lee, Vladislav Voroninski, Stefano Soatto
2016 arXiv   pre-print
We introduce a new method for location recovery from pair-wise directions that leverages an efficient convex program that comes with exact recovery guarantees, even in the presence of adversarial outliers  ...  Our proposed numerical framework is flexible in that it accommodates other approaches to location recovery and can be used to speed up other methods.  ...  Introduction The typical structure-from-motion (SfM) pipeline consists of (i) establishing sparse correspondence between local regions in different images of a (mostly) rigid scene, (ii) exploiting constraints  ...

A Survey of Structure from Motion [article]

Onur Ozyesil, Vladislav Voroninski, Ronen Basri, Amit Singer
2017 arXiv   pre-print
The structure from motion (SfM) problem in computer vision is the problem of recovering the three-dimensional (3D) structure of a stationary scene from a set of projective measurements, represented as  ...  e.g., using relative pairwise camera positions estimated from the extracted features), and (3) recovery of the 3D structure using the estimated motion and features (e.g., by minimizing the so-called reprojection  ...  and theoretical analysis of stability, robustness and computational efficiency of existing or new methods. Figure 1 : 1 The structure from motion (SfM) problem.  ...
