Multi-modal non-line-of-sight passive imaging

A Beckus, A Tamasan, GK Atia - IEEE Transactions on Image …, 2019 - ieeexplore.ieee.org
We consider the non-line-of-sight (NLOS) imaging of an object using the light reflected off a
diffusive wall. The wall scatters incident light such that a lens is no longer useful to form an …
