Abstract

A passively illuminated scene presents a variety of photon pathways: direct and indirect, which convey varying levels of information about the scene across different dimensions of the light field. In indirect passive imaging, the object of interest is occluded from the imager which has no control over illumination. Using a second-order (non-linear) image formation model we demonstrate (experimentally) the feasibility of passive indirect diffuse imaging.
