Cast-Shadow Removal for Cooperative Adaptive Appearance Manipulation

Abstract

We propose a framework to suppress over-illumination at the overlapping area created by cooperative adaptive appearance manipulation with independently working two projector-camera systems. The proposed method estimates projection overlapping in each projector-camera unit with neither geometrical mapping nor projection image sharing. Then, the method suppresses the projection illumination of the overlapping area by compensated reflectance estimation. Experimental results using two projector-camera systems confirm that the proposed method correctly detects overlapping areas adaptively and removes cast shadows that cause uneven illumination owing to cooperative appearance manipulation of a moving 3D target.
