PI-NLOS: polarized infrared non-line-of-sight imaging
Optics Express, 2023 Passive non-line-of-sight (NLOS) imaging is a promising technique to enhance visual perception for the occluded object hidden behind the wall. Here we present a data-driven NLOS imaging framework by using polarization cue and long-wavelength infrared (LWIR) images.
