Computational Illumination

Abstract

The field of computational photography includes computational imaging techniques that enhance or extend the capabilities of digital photography, a combination of computer vision, computer graphics, and applied optics. Computational illumination is an aspect of computational photography that considers how to modify illumination in order to facilitate useful techniques in computer vision and imaging. This talk will present research using multiflash imaging, coded shadow photography, and parameterized structured light, three families of techniques in computational illumination, where the results help to produce reliable information in scenes that is often difficult to robustly compute otherwise.
