Light in Flight

Transient imaging, or light-in-flight imaging, refers to the capture and analysis of light transport at nanosecond and picosecond scales. We develop devices and methods to enable the capture and processing of such data at low cost and unprecedented speed, and to robustly reconstruct 3D scene information within and even beyond the line of sight.

Inverse Rendering

In computer graphics, we pride ourselves on performant and accurate forward simulation of light (rendering). Here, we use graphics as methodology to solve problems beyond the generation of pretty pictures. By marrying extremely efficient forward renderers to numerical optimization methods, we develop novel analysis-by-synthesis approaches that push the boundaries on challenging problems like 3D surface reconstruction, real-time tracking of occluded objects from indirect diffuse light reflections, and light field imaging through uncalibrated free-form optics.

Digital Material Appearance

Accurate and detailed representations of real-world materials are a crucial ingredient to any computer graphics application. An important strand of our research is dedicated to developing new methods for the acquisition, representation, manipulation and reproduction of digital material models, and understanding the factors that contribute to successful communication of measurable and subjective material properties.
