Definition

Light transport describes how the light propagates into a known 3D scene. The inverse light transport problem takes a set of images of an unknown scene as input and infers the light transport process in the scene.

Background

Although the light transport simulation and acquisition have been well studied in computer graphics, the inverse light transport is still an open problem and hasn’t been systematically investigated. This is due to the complexity of the paths of light propagation in the scene, as well as variations of surface BRDFs along each light path. The problem becomes even more challenging when the scene geometry and illumination are unknown.

A set of inverse light transport methods [3, 10, 14] decompose the light transport into the direct lighting and indirect lighting parts. Most of these methods make some assumptions about the scene reflectance or lighting...
