3D Scene Flow from 4D Light Field Gradients

Sizhuo Ma, Brandon M. Smith, Mohit Gupta

ECCV 2018poster

This paper presents novel techniques for recovering 3D dense scene flow, based on differential analysis of 4D light fields. The key enabling result is a per-ray linear equation, called the ray flow equation, that relates 3D scene flow to 4D light field gradients. The ray flow equation is invariant t…

Tracking Multiple Objects Outside the Line of Sight Using Speckle Imaging

Brandon M. Smith, Matthew O'Toole, Mohit Gupta

CVPR 2018poster

This paper presents techniques for tracking non-line-of-sight (NLOS) objects using speckle imaging. We develop a novel speckle formation and motion model where both the sensor and the source view objects only indirectly via a diffuse wall. We show that this NLOS imaging scenario is analogous to dire…
