High Flux Passive Imaging with Single-Photon Sensors
Our key observation is that the precise inter-photon timing measured by a SPAD can be used for estimating scene brightness under ambient lighting conditions, even for very bright scenes.
Photon-Flooded Single-Photon 3D Cameras
Single photon avalanche diodes (SPADs) are starting to play a pivotal role in the development of photon-efficient, long-range LiDAR systems.
Asynchronous Single-Photon 3D Imaging
Single-photon avalanche diodes (SPADs) are becoming popular in time-of-flight depth-ranging due to their unique ability to capture individual photons with picosecond timing resolution.
Passive Inter-Photon Imaging
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.
Compressive Single-Photon 3D Cameras
CSPHs are a per-pixel compressive representation of the high-resolution histogram, that is built on-the-fly, as each photon is detected.
3D Scene Inference from Transient Histograms
Time-resolved image sensors that capture light at pico-to-nanosecond timescales were once limited to niche applications but are now rapidly becoming mainstream in consumer devices.
Learned Compressive Representations for Single-Photon 3D Imaging
Single-photon 3D cameras can record the time-of-arrival of billions of photons per second with picosecond accuracy.
Count-Free Single-Photon 3D Imaging with Race Logic
The two key ingredients of our approach are (a) processing photon streams using race logic, which maintains photon data in the time-delay domain, and (b) constructing count-free equi-depth histograms.
Panoramas from Photons
Here we present a method capable of estimating extreme scene motion under challenging conditions, such as low light or high dynamic range, from a sequence of high-speed image frames such as those captured by a single-photon camera.
