3D Scene Inference from Transient Histograms

no code implementations9 Nov 2022 Sacha Jungerman, Atul Ingle, Yin Li, Mohit Gupta

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.

Compressive Single-Photon 3D Cameras

no code implementations CVPR 2022 Felipe Gutierrez-Barragan, Atul Ingle, Trevor Seets, Mohit Gupta, Andreas Velten

CSPHs are a per-pixel compressive representation of the high-resolution histogram, that is built on-the-fly, as each photon is detected.

Passive Inter-Photon Imaging

no code implementations CVPR 2021 Atul Ingle, Trevor Seets, Mauro Buttafava, Shantanu Gupta, Alberto Tosi, Mohit Gupta, Andreas Velten

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.

Asynchronous Single-Photon 3D Imaging

no code implementations ICCV 2019 Anant Gupta, Atul Ingle, Mohit Gupta

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.

Photon-Flooded Single-Photon 3D Cameras

no code implementations CVPR 2019 Anant Gupta, Atul Ingle, Andreas Velten, Mohit Gupta

Single photon avalanche diodes (SPADs) are starting to play a pivotal role in the development of photon-efficient, long-range LiDAR systems.

High Flux Passive Imaging with Single-Photon Sensors

no code implementations CVPR 2019 Atul Ingle, Andreas Velten, Mohit Gupta

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.
