Abstract

In conventional predictive quantization schemes for 3-D mesh geometry, excessively large residuals or prediction errors, although occasional, lead tovisually unacceptable geometric distortion. This is due to the fact that they cannot Limit the maximum quantization error within a given bound. In order to completely eliminate the visually unacceptable distortion caused by large residuals, we propose a predictive two-stage quantization scheme. This scheme is very similar to the conventional DPCM, except that the embeddedquantizer is replaced by a series of two quantizers. Each quantizer outputis further compressed by an arithmetic code. When applied to typical 3-D mesh models, the scheme performs much better than the conventional predictive quantization methods and, depending upon input models, even than the MPEG-4 compression method for 3-D mesh geometry both in rate-distortion sense and in subjective viewing.
