Viewpoint-Dependent Appearance-Manipulation with Multiple Projector-Camera Systems

Abstract

This paper proposes a novel projection display technique that realizes viewing-direction-dependent appearance-manipulation. The proposed method employs a multiple projector-camera feedback system, and each projector-camera system simultaneously manipulates the apparent color or contrast from the different viewing directions. Since we assume the mirror reflection is a dominant component, we placed the camera on the counter side of the projector for the system. We confirmed that our multiple projector-camera system enables viewpoint-dependent appearance-manipulation on an anisotropic reflection surface by the experimental results. Interestingly, the application target is not limited to a metallic surface, and we have confirmed that it can be applied to matte paper media for glossy ink reflection.
