Fast Task-Based Adaptive Sampling for 3D Single-Photon Multispectral Lidar Data

no code implementations3 Sep 2021 Mohamed Amir Alaa Belmekki, Rachael Tobin, Gerald S. Buller, Stephen McLaughlin, Abderrahim Halimi

Given a task of interest, the iterative sampling strategy targets the most informative regions of a scene which are defined as those minimizing parameter uncertainties.

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.

Robust and Guided Bayesian Reconstruction of Single-Photon 3D Lidar Data: Application to Multispectral and Underwater Imaging

no code implementations18 Mar 2021 Abderrahim Halimi, Aurora Maccarone, Robert Lamb, Gerald S. Buller, Stephen McLaughlin

3D Lidar imaging can be a challenging modality when using multiple wavelengths, or when imaging in high noise environments (e. g., imaging through obscurants).

Robust super-resolution depth imaging via a multi-feature fusion deep network

1 code implementation20 Nov 2020 Alice Ruget, Stephen McLaughlin, Robert K. Henderson, Istvan Gyongy, Abderrahim Halimi, Jonathan Leach

The network is designed for a SPAD camera operating in a dual-mode such that it captures alternate low resolution depth and high resolution intensity images at high frame rates, thus the system does not require any additional sensor to provide intensity images.

Correntropy Maximization via ADMM - Application to Robust Hyperspectral Unmixing

no code implementations4 Feb 2016 Fei Zhu, Abderrahim Halimi, Paul Honeine, Badong Chen, Nanning Zheng

In hyperspectral images, some spectral bands suffer from low signal-to-noise ratio due to noisy acquisition and atmospheric effects, thus requiring robust techniques for the unmixing problem.
