• 論文抄録 / 内容記述: Shadows play an important role in the human perception of 3D geometry in photographs, and properly synthesized shadows produce a realistic rendering result. Shadows, especially hard shadows, define powerful constraints between a light source, occluders, and the surfaces onto which shadows are cast. In our previous work, we had proposed a method to create a pseudo 3D scene in which a light produces shadows that are the same as those in the input image, and the proposed method produces realistic shadows in real-time while enabling editing of the pseudo scene. In this paper, using 3D models and synthesized images in which a 3D model casts a hard shadow on a plane, we evaluate the consistency of the shadow cast by the pseudo 3D shape created by our object shape estimation method.
