Plenoptic imaging of particle interactions in scintillation detectors
Xiang Dai, Chi-Jui Ho, Kevin Tandi +9
Accurate 3D localization of radiation interactions in scintillation detectors is essential for nuclear and particle physics, safeguards, and medical imaging, but remains difficult…
Deep Feature-specific Imaging
Yizhou Lu, Andreas Velten
Modern photon-counting sensors are increasingly dominated by Poisson noise, yet conventional feature-specific imaging (FSI), based on principal component analysis (PCA), is optimiz…
A comprehensive study of time-of-flight non-line-of-sight imaging
Julio Marco, Adrian Jarabo, Ji Hyun Nam +3
Time-of-Flight non-line-of-sight (ToF NLOS) imaging techniques provide state-of-the-art reconstructions of scenes hidden around corners by inverting the optical path of indirect ph…
Hardware-aware Coding Function Design for Compressive Single-Photon 3D Cameras
David Parra, Felipe Gutierrez-Barragan, Trevor Seets +1
Single-photon cameras are becoming increasingly popular in time-of-flight 3D imaging because they can time-tag individual photons with extreme resolution. However, their performanc…
Optimized Sampling for Non-Line-of-Sight Imaging Using Modified Fast Fourier Transforms
Talha Sultan, Alex Bocchieri, Chaoying Gu +3
Non-line-of-Sight (NLOS) imaging systems collect light at a diffuse relay surface and input this measurement into computational algorithms that output a 3D volumetric reconstructio…
Iterating the Transient Light Transport Matrix for Non-Line-of-Sight Imaging
Talha Sultan, Eric Brandt, Khadijeh Masumnia-Bisheh +4
Active imaging systems sample the Transient Light Transport Matrix (TLTM) for a scene by sequentially illuminating various positions in this scene using a controllable light source…
