Fast non-line-of-sight imaging with high-resolution and wide field of view using synthetic wavelength holography
The presence of a scattering medium in the imaging path between an object and an
observer is known to severely limit the visual acuity of the imaging system. We present an …

Non-line-of-sight imaging via neural transient fields
We present a neural modeling framework for non-line-of-sight (NLOS) imaging. Previous
solutions have sought to explicitly recover the 3D geometry (eg, as point clouds) or voxel …

Learning diffractive optical communication around arbitrary opaque occlusions
Free-space optical communication becomes challenging when an occlusion blocks the light
path. Here, we demonstrate a direct communication scheme, passing optical information …

Humans as light bulbs: 3d human reconstruction from thermal reflection
R Liu, C Vondrick - … of the IEEE/CVF Conference on …, 2023 - openaccess.thecvf.com
The relatively hot temperature of the human body causes people to turn into long-wave
infrared light sources. Since this emitted light has a larger wavelength than visible light …

Optical non-line-of-sight physics-based 3d human pose estimation
We describe a method for 3D human pose estimation from transient images (ie, a 3D spatio-
temporal histogram of photons) acquired by an optical non-line-of-sight (NLOS) imaging …

Convolutional approximations to the general non-line-of-sight imaging operator
Abstract Non-line-of-sight (NLOS) imaging aims to reconstruct scenes outside the field of
view of an imaging system. A common approach is to measure the so-called light transients …
