High-speed object detection with a single-photon time-of-flight image sensor

no code implementations28 Jul 2021 Germán Mora-Martín, Alex Turpin, Alice Ruget, Abderrahim Halimi, Robert Henderson, Jonathan Leach, Istvan Gyongy

The results, obtained with exposure times down to 2 ms (equivalent to 500 FPS) and in signal-to-background (SBR) ratios as low as 0. 05, point to the advantages of providing the CNN with full histogram data rather than point clouds alone.

A pulse oximeter based on Time-of-Flight histograms

no code implementations25 Feb 2021 Yuanyuan Hua, Konstantinos Bantounos, Aravind Venugopalan Nair Jalajakumari, Alex Turpin, Ian Underwood, Danial Chitnis

Traditionally, these devices estimate the oxygenation level by measuring the intensity of the transmitted light through the tissue and are embedded into everyday devices such as smartphones and smartwatches.

3D imaging from multipath temporal echoes

no code implementations17 Nov 2020 Alex Turpin, Valentin Kapitany, Jack Radford, Davide Rovelli, Kevin Mitchell, Ashley Lyons, Ilya Starshynov, Daniele Faccio

Echo-location is a broad approach to imaging and sensing that includes both man-made RADAR, LIDAR, SONAR and also animal navigation.

Spatial images from temporal data

no code implementations2 Dec 2019 Alex Turpin, Gabriella Musarra, Valentin Kapitany, Francesco Tonolini, Ashley Lyons, Ilya Starshynov, Federica Villa, Enrico Conca, Francesco Fioranelli, Roderick Murray-Smith, Daniele Faccio

Traditional paradigms for imaging rely on the use of a spatial structure, either in the detector (pixels arrays) or in the illumination (patterned light).
