Revealing hidden scenes by photon-efficient occlusion-based opportunistic active imaging
Feihu Xu, Gal Shulkind, Christos Thrampoulidis +4
The ability to see around corners, i.e., recover details of a hidden scene from its reflections in the surrounding environment, is of considerable interest in a wide range of appli…
Single-Photon Depth Imaging Using a Union-of-Subspaces Model
Dongeek Shin, Jeffrey H. Shapiro, Vivek K Goyal
Light detection and ranging systems reconstruct scene depth from time-of-flight measurements. For low light-level depth imaging applications, such as remote sensing and robot visio…
Photon-Efficient Computational 3D and Reflectivity Imaging with Single-Photon Detectors
Dongeek Shin, Ahmed Kirmani, Vivek K Goyal +1
Capturing depth and reflectivity images at low light levels from active illumination of a scene has wide-ranging applications. Conventionally, even with single-photon detectors, hu…
