由于互联网上3D网格交换的大规模发展，这种数据的传输和保护最近受到了特别关注。本文提出了一种在网格谱域中对三维三角形网格的几何信息进行压缩和水印的方法。我们首先解释如何提高质量的压缩使用重叠，然后我们提出了一个替代水印方案在网格频谱域。最后，我们给出了一个概述的压缩或水印所获得的结果。证明了水印算法对压缩方法的鲁棒性。
Due to massive development of 3D meshes exchanges on the Internet, transmission and protection of such data has recently received a special focus. In this paper we present a method to compress and watermark the geometry of a 3D triangle mesh in the mesh spectral domain. We first explain how to improve the quality of the compression using overlapping, then we propose a substitutive watermarking scheme in the mesh spectral domain. Finally, we give an overview of the results obtained both for compression or watermarking. The robustness of the watermarking algorithm against the compression method is demonstrated.
