In our daily lives, we observe a variety of interesting visual effects, such as the glow around street-lights in fog, the soft appearance of translucent objects like skin, plants and marble, different colors of liquids like wine and milk or the splendor of underwater effects. Such visual effects are produced due to complex interactions of light with the world around us. These interactions, in the form of inter-reflections, subsurface scattering and volumetric scattering, are collectively termed as global light transport.
The focus of my research is to understand the complex effects of global light transport on the image formation process, for applications in Computer Graphics and Vision. In particular, my research addresses the following issues related to scene recovery and rendering in the presence of global light transport (click on images for details):
(De) Focused Illumination and Global Light Transport
Underwater Imaging: Seeing clearer and farther in poor visibility scenarios
Fast Simulation and Rendering of Dynamic, Non-homogenous Volumetric Media
Measuring Scattering Properties of Volumetric Media
High Resolution Tracking of Facial Expressions
