One Photon, Many Worlds: Posteriors and Predictions with Single-Photon Cameras
Haejoon Lee, Mohit Gupta, Vijayakumar Bhagavatula +1
Single-photon avalanche diode (SPAD) cameras operate fundamentally differently from conventional cameras due to their photon-counting nature. Each frame produces a binary image: pi…
Provable and Robust Wavefront Sensing via Self-Reference Interferometry
Nebiyou Yismaw, Vishwanath Saragadam, Aswin C. Sankaranarayanan +1
Wavefront sensing involves estimating the phase and intensity of light, enabling a wide range of imaging applications, from adaptive optics and astronomy to biomedical imaging. Sin…
Precise Forecasting of Sky Images Using Spatial Warping
Leron Julian, Aswin C. Sankaranarayanan
The intermittency of solar power, due to occlusion from cloud cover, is one of the key factors inhibiting its widespread use in both commercial and residential settings. Hence, rea…
Angle Sensitive Pixels for Lensless Imaging on Spherical Sensors
Yi Hua, Yongyi Zhao, Aswin C. Sankaranarayanan
We propose OrbCam, a lensless architecture for imaging with spherical sensors. Prior work in lensless imager techniques have focused largely on using planar sensors; for such desig…
PSF: Polarized Spiral Point Spread Function for Single-Shot 3D Sensing
Bhargav Ghanekar, Vishwanath Saragadam, Dushyant Mehra +3
We propose a compact snapshot monocular depth estimation technique that relies on an engineered point spread function (PSF). Traditional approaches used in microscopic super-resolu…
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,…
