Abstract:
In this paper, we propose an efficient method for rendering virtual objects into real scene images. We put a diffuse sphere into the scene as a reference object, and use the direct relationship between the intensity of the diffuse sphere and the intensity of virtual objects for rendering the virtual objects in images. We also generate shadows of the virtual objects by using shadows of the reference sphere. As a result, arbitrary virtual objects and their shadows can be rendered quite efficiently from a single diffuse sphere put in the scene. The proposed method is tested in real image experiments, and evaluated quantitatively comparing with the existing method.
