Turning corners into cameras: Principles and methods

KL Bouman, V Ye, AB Yedidia… - Proceedings of the …, 2017 - openaccess.thecvf.com
We show that walls and other obstructions with edges can be exploited as naturally-
occurring" cameras" that reveal the hidden scenes beyond them. In particular, we …

Using unknown occluders to recover hidden scenes

AB Yedidia, M Baradad… - Proceedings of the …, 2019 - openaccess.thecvf.com
We consider the challenging problem of inferring a hidden moving scene from faint shadows
cast on a diffuse surface. Recent work in passive non-line-of-sight (NLoS) imaging has …

Inferring light fields from shadows

M Baradad, V Ye, AB Yedidia… - Proceedings of the …, 2018 - openaccess.thecvf.com
We present a method for inferring a 4D light field of a hidden scene from 2D shadows cast
by a known occluder on a diffuse wall. We do this by determining how light naturally …

Computational mirrors: Blind inverse light transport by deep matrix factorization

M Aittala, P Sharma, L Murmann… - Advances in neural …, 2019 - proceedings.neurips.cc
We recover a video of the motion taking place in a hidden scene by observing changes in
indirect illumination in a nearby uncalibrated visible region. We solve this problem by …

Accidental cameras: creating images from shadows

V Ye - 2018 - dspace.mit.edu
In this thesis, we explore new imaging systems that arise from everyday occlusions and
shadows. By modeling the structured shadows created by various occlusions, we are able to …
