Single-Photon Structured Light
Varun Sundar, Sizhuo Ma, Aswin C. Sankaranarayanan +1
We present a novel structured light technique that uses Single Photon Avalanche Diode (SPAD) arrays to enable 3D scanning at high-frame rates and low-light levels. This technique,…

Differential Scene Flow from Light Field Gradients
Sizhuo Ma, Brandon M. Smith, Mohit Gupta
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, ca…
