[PDF][PDF] Optical computing for fast light transport analysis

M O'Toole, KN Kutulakos - ACM Trans. Graph, 2010 - Citeseer
We present a general framework for analyzing the transport matrix of a real-world scene at
full resolution, without capturing many photos. The key idea is to use projectors and cameras …

A dual theory of inverse and forward light transport

J Bai, M Chandraker, TT Ng, R Ramamoorthi - Computer Vision–ECCV …, 2010 - Springer
Inverse light transport seeks to undo global illumination effects, such as interreflections, that
pervade images of most scenes. This paper presents the theoretical and computational …

Shape from second-bounce of light transport

S Liu, TT Ng, Y Matsushita - Computer Vision–ECCV 2010: 11th European …, 2010 - Springer
This paper describes a method to recover scene geometry from the second-bounce of light
transport. We show that form factors (up to a scaling ambiguity) can be derived from the …

radiometric compensation using color-mixing matrix reformed from light transport matrix
