摘要：3-D video records dynamic 3-D visual events as is. Applications of 3-D video include wide varieties of human activities. For promoting these applications in everyday life, a standardized compression scheme for 3-D video is required. We developed a practical and effective scheme for representing and compressing 3-D video named “skin-off,” in which both the geometric and visual information are efficiently represented by cutting a 3-D mesh and mapping it onto a 2-D array. Skin-off has much in common with geometry images proposed by Gu et al. However, while geometry images use only 3-D surface shape information to generate 2-D images, skin-off uses both 3-D shape and texture information to generate them. This enables us to achieve higher image quality with limited bandwidth. Experimental results demonstrate the effectiveness of skin-off.
