Photometric Stereo by Hemispherical Metric Embedding
Ofer Bartal, Nati Ofir, Yaron Lipman +1
Photometric Stereo methods seek to reconstruct the 3d shape of an object from motionless images obtained with varying illumination. Most existing methods solve a restricted problem…
On Detection of Faint Edges in Noisy Images
Nati Ofir, Meirav Galun, Sharon Alpert +3
A fundamental question for edge detection in noisy images is how faint can an edge be and still be detected. In this paper we offer a formalism to study this question and subsequen…
A New Rank Constraint on Multi-view Fundamental Matrices, and its Application to Camera Location Recovery
Soumyadip Sengupta, Tal Amir, Meirav Galun +4
Accurate estimation of camera matrices is an important step in structure from motion algorithms. In this paper we introduce a novel rank constraint on collections of fundamental ma…
Solving Uncalibrated Photometric Stereo Using Fewer Images by Jointly Optimizing Low-rank Matrix Completion and Integrability
Soumyadip Sengupta, Hao Zhou, Walter Forkel +3
We introduce a new, integrated approach to uncalibrated photometric stereo. We perform 3D reconstruction of Lambertian objects using multiple images produced by unknown, directiona…
A Survey of Structure from Motion
Onur Ozyesil, Vladislav Voroninski, Ronen Basri +1
The structure from motion (SfM) problem in computer vision is the problem of recovering the three-dimensional (D) structure of a stationary scene from a set of projective measur…
