    • Research

    The Illumination and Imaging (ILIM) laboratory at the Robotics Institute is dedicated to the study of light transport and the development of novel illumination and imaging technologies. The laboratory is part of the broader computer vision and computer graphics groups at Carnegie Mellon. Our research is motivated by applications in the areas of digital imaging, computer vision, computer graphics and robotics. Selected projects are highlighted below. Please visit the official RI webpage for a list of publications. The sponsors for these research projects include Office of Naval Research (ONR), Defense Advanced Projects Research Agency (DARPA), National Science Foundation (NSF), and Siemens Corporate Research, Princeton (SCR).
