Adaptive multi-resolution coding for 3D scenes using vector quantization

This paper proposes a multi-resolution coding system for 3D graphic scenes using vector quantization (VQ). For improved compression efficiency, the proposed system generates the VQ codebook for a given 3D scene using mesh objects contained in the scene database instead of separate training models. Furthermore, objects are weighted according to their unequal display importance resulting from interactions, which is incorporated into both codebook training and rate-distortion optimization. Empirical results are presented to verify the efficiency of the proposed coding system.
