Digital camera pixels measure image intensities by converting incident light energy into an analog electrical current, and then digitizing it into a fixed-width binary representation. This direct measurement method, while conceptually simple, suffers from limited dynamic range and poor performance under extreme illumination — electronic noise dominates under low illumination, and pixel full-well capacity results in saturation under bright illumination. We propose a novel intensity cue based on… Expand

Passive imaging of single photon flux: strategies for de-noising, motion blur reduction and super-resolution up-scaling
Single photon-counting avalanche photo-diode (SPAD) can measure the photon flux from uncorrelated single photons. In present work, we show how the sensor photon count rate is related to the intensityExpand


High Flux Passive Imaging With Single-Photon Sensors
A theoretical model for passive free-running SPAD imaging is developed, and a scene brightness estimator based on the average time of darkness between successive photons detected by a PF-SPAD pixel is derived, which demonstrates an improvement of over 2 orders of magnitude over conventional sensors by imaging scenes spanning a dynamic range of 10^6:1. Expand
First-Photon Imaging
First-photon imaging is introduced, which is a computational imager that exploits spatial correlations found in real-world scenes and the physics of low-flux measurements, and recovers 3D structure and reflectivity from the first detected photon at each pixel. Expand
Quanta burst photography
This work designs algorithms that align and merge binary sequences captured by SPCs into intensity images with minimal motion blur and artifacts, high signal-to-noise ratio (SNR), and high dynamic range, and theoretically analyzes the SNR and dynamic range of quanta burst photography. Expand
Reconstructing Transient Images from Single-Photon Sensors
In this work, an imaging system that builds on single photon avalanche diode (SPAD) sensors to capture multi-path responses with picosecond-scale active illumination is designed and evaluated and inverse methods that use modern approaches to deconvolve and denoise measurements in the presence of Poisson noise are developed.

Single photon range, intensity and photon flux imaging with kilohertz frame rate and high dynamic range.
This paper compares time correlated and uncorrelated imaging of single photon events using an InGaAs single-photon-counting-avalanche-photo-diode (SPAD) sensor with a 32 × 32 focal plane array detector and demonstrates imaging, ranging and photon flux measurements of a moving target from a few samples with a frame rate of 50 kHz.

The end result is an imaging system that can measure a very wide range of scene radiance and produce a substantially larger number of brightness levels, with a slight reduction in spatial resolution. Expand
32 × 32 CMOS SPAD Imager for Gated Imaging, Photon Timing, and Photon Coincidence

Three-dimensional imaging through scattering media based on confocal diffuse tomography
This work introduces a technique that co-designs single-photon avalanche diodes, ultra-fast pulsed lasers, and a new inverse method to capture 3D shape through scattering media, and demonstrates acquisition of shape and position for objects hidden behind a thick diffuser at macroscopic scales.

Looking around the corner using transient imaging
We show that multi-path analysis using images from a timeof-flight (ToF) camera provides a tantalizing opportunity to infer about 3D geometry of not only visible but hidden parts of a scene. WeExpand
