Compression of 3D objects with multistage color-depth panoramic maps

Abstract

Summary form only given. A new representation method, the multistage color-depth panoramic map (or panomap), is proposed for compressing 3D graphic objects. The idea of the proposed method is to transform a 3D graphic object, including both the shape and color information, into a single image. Existing image compression techniques can then be applied for compressing the panomap structure, which can achieve a highly efficient representation due to its regularity. In our experiments, compressing the color part of a CMP with a lossy method (JPEG) and the depth part with a lossless one (PNG) achieves good reconstruction quality with low bit rates.
