Virtual view networks for object reconstruction

All that structure from motion algorithms “see ” are sets of 2D points. We show that these impoverished views of the world can be faked for the purpose of reconstructing objects in challenging settings, such as from a single im-age, or from a few ones far apart, by recognizing the object and getting help from a collection of images of other ob-jects from the same class. We synthesize virtual views by computing geodesics on networks connecting objects with similar viewpoints, and introduce techniques to increase the specificity and robustness of factorization-based object re-construction in this setting. We report accurate object shape reconstruction from a single image on challenging PASCAL VOC data, which suggests that the current domain of appli-cations of rigid structure-from-motion techniques may be significantly extended. 1.
