The application areas of 3D video include wide varieties of human activities. To promote these applications in our everyday life, a standardized compression scheme for 3D video is required. In this paper, we propose a practical and effective scheme for representing and compressing 3D video named skin-off, in which both the geometric and visual information are efficiently represented by cutting a 3D mesh and mapping it onto a 2D array. Our skin-off scheme shares much with geometry videos, proposed by Hoppe et al. However, while geometry videos employ the 3D surface shape information alone to generate 2D images, the skin-off scheme we are proposing employs both 3D shape and texture information to generate them. This enables us to achieve higher image quality with limited bandwidth. Experimental results demonstrate the effectiveness of the skin-off scheme.

The content may be of three kinds: live-action movies, 3DCG movies, and animated cartoon. In this talk we will describe a set of in-house tools to efficiently convert from Japanese hand-drawn animation to stereoscopic animation.
