Abstract

This paper presents an approach that can relight captured image with real incident light source. We first captured basis images of objects illuminated with a projector as the basis light source. We then established a pixel level mapping relationship between a real incident light source and the basis light source. Finally we developed a relighting algorithm that can simulate the relit effects with the real light source. The techniques can be applied to mixed reality.
