Light Transport for Vision and Graphics

Model Reducing Radiosity of Deformable Scenes
Novel mathematical framework to extend Galerkin projection to non-polynomial functions with applications to fast fluid simulation and radiosity rendering of deformable scenes.
Radiosity of Translucent Scenes
The goal of the project is to efficiently render both the subsurface scattering of light within objects and the diffuse interreflections between them.
Structured light 3D under Global Illumination
The goal is to recover 3D shapes of complex objects using structured lighting that is robust to interreflections, sub-surface scattering and defocus.
(De)Focused Illumination and Global Light Transport
The goal is to recover depth from defocus in the presence of global illumination.
Structured Light in Scattering Media
Laser range finding and photometric stereo in impure waters.
Optimal placement of cameras and sources in scattering media
Optimal positioning of light sources and cameras for best visibility in impure waters.
Frequency Space Analysis of Rain and Snow
Removing rain and snow from videos using a frequency space analysis.
Shedding light on the weather
Estimating visibility and weather condition from light source appearances.
Vision through Fog and Haze
Models and algorithms for recovering scene properties from images captured in fog and haze.
WILD Database
Calibrated and HDR time-lapse images of an outdoor scene for a year.
Legendre Fluids
We present a unified framework for reduced space modeling and rendering of dynamic and non-homogenous participating media, like snow, smoke, dust and fog.
Scattering Properties by Dilution
We have developed a simple device and technique for robustly estimating the properties of a broad class of participating media.
Single Scattering Model
We are interested in analyzing and rendering the visual effects due to scattering of light by participating media such as fog, mist and haze.
Multiple Scattering
This project focuses on multiple scattering from light sources immersed in participating media such as bad weather and fluids.
