Trapping Light for Time of Flight

no code implementations CVPR 2018 Ruilin Xu, Mohit Gupta, Shree K. Nayar

We propose a novel imaging method for near-complete, surround, 3D reconstruction of geometrically complex objects, in a single shot.

AirCode: Unobtrusive Physical Tags for Digital Fabrication

no code implementations18 Jul 2017 Dingzeyu Li, Avinash S. Nair, Shree K. Nayar, Changxi Zheng

We present AirCode, a technique that allows the user to tag physically fabricated objects with given information.

SpeDo: 6 DOF Ego-Motion Sensor Using Speckle Defocus Imaging

no code implementations ICCV 2015 Kensei Jo, Mohit Gupta, Shree K. Nayar

We develop a theoretical model for speckle flow (motion of speckle as a function of sensor motion), and show that it is quasi-invariant to surrounding scene's properties.

Extended Depth of Field Catadioptric Imaging Using Focal Sweep

no code implementations ICCV 2015 Ryunosuke Yokoya, Shree K. Nayar

We show that while the IPSF is spatially varying when a curved mirror is used, it remains quasi depth-invariant over the wide field of view of the imaging system.
