Model-based bit allocation for normal mesh compression

摘要: In this paper, we propose a powerful bit allocation that optimizes the quantization of normal mesh geometry. This aims to minimize surface-to-surface distance [P. Cignoni et al., 1998] between original irregular and quantized one, according target bitrate. Moreover, provide fast allocation, approximate with simple criterion depending on wavelet coefficient distributions, use theoretical models. provides low-complex model-based yielding results better than recent state-of-the-art methods like [A. Khodakovsky I. Guskov, 2002].
