Radiometric compensation for ubiquitous projection.

Integrating a pico-projector with a multimedia device allows a nearby wall, desk, or human body to be conveniently used as the projection surface. Ubiquitous projection is no longer a fiction, and the miniature of projector brings about a new form of social interaction and augmented reality applications. This paper gives an overview of the key advances in radiometric compensation for ubiquitous projection and discusses the technical issues associated with the physical limitations of projectors and cameras in spatial resolution and dynamic range. Existing techniques that can be applied to address these issues are reviewed, and open issues for future research are discussed.
