Postproduction Re-Illumination of Live Action Using Time-Multiplexed Lighting

Abstract

In this work, we present a technique for capturing a time-varying human performance in such a way that it can be re-illuminated in postproduction. The key idea is to illuminate the subject with a variety of rapidly changing time-multiplexed basis lighting conditions, and to record these lighting conditions with a fast enough video camera so that several or many different basis lighting conditions are recorded during the span of the final video's desired frame rate. In this poster we present two versions of such a system and propose plans for creating a complete, production-ready device.
