The latest wavelet based 3D mesh coding schemes convert an irregular mesh into a semi-regular mesh and directly apply the zerotree-like image coders to compress the wavelet vectors generated in the remeshing process. The major problem of such type of approaches is that the particular properties of semi-regular meshes are not being considered in the zerotreelike image coders. In this paper, we propose an improved wavelet based 3D mesh coder. The basic idea is to introduce a preprocessing step to scale up the vector wavelets generated in remeshing so that the inherent dependency of wavelets can be truly understood by the zerotree-like image compression algorithms. The weights used in the scaling process are carefully designed through thoroughly analyzing the distortions of wavelets at different refinement levels. Experimental results show that our proposed mesh coder significantly outperforms the state-of-the-art wavelet based 3D mesh compression scheme.
