Polarized Non-Line-of-Sight Imaging
2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2020This paper presents a method of passive non-line-of-sight (NLOS) imaging using polarization cues. A key observation is that the oblique light has a different polarimetric signal. It turns out this effect is due to the polarization axis rotation, a phenomena which can be used to better condition the light transport matrix for non-line-of-sight imaging ...

Thermal Non-Line-of-Sight Imaging
2019 IEEE International Conference on Computational Photography (ICCP), 2019We propose a novel non-line-of-sight (NLOS) imaging framework with long-wave infrared (IR). At long-wave IR wavelengths, certain physical parameters are more favorable for high-fidelity reconstruction. In contrast to prior work in visible light NLOS, at long-wave IR wavelengths, the hidden heat source acts as a light source. This simplifies the problem

Passive Non-Line-of-Sight Imaging Using Optimal Transport
IEEE Transactions on Image Processing, 2022Passive non-line-of-sight (NLOS) imaging has drawn great attention in recent years. However, all existing methods are in common limited to simple hidden scenes, low-quality reconstruction, and small-scale datasets. In this paper, we propose NLOS-OT, a novel passive NLOS imaging framework based on manifold embedding and optimal transport, to reconstruct

Real-time non-line-of-sight imaging
ACM SIGGRAPH 2018 Emerging Technologies, 2018Non-line-of-sight (NLOS) imaging aims at recovering the shape of objects hidden outside the direct line of sight of a camera. In this work, we report on a new approach for acquiring time-resolved measurements that are suitable for NLOS imaging. The system uses a confocalized single-photon detector and pulsed laser.

Non-line-of-sight underwater optical wireless communication network
Journal of the Optical Society of America A, 2009The growing need for ocean observation systems has stimulated considerable interest within the research community in advancing the enabling technologies of underwater wireless communication and underwater sensor networks. Sensors and ad hoc sensor networks are the emerging tools for performing extensive data-gathering operations on land, and solutions ...
