Abstract :
In order to describe mesh bit-streams which can be adapted to the heterogeneity of network bandwidth and terminals graphics capabilities, the concepts of quality scalability and resolution scalability are introduced. A triangle mesh compression scheme based on wavelet transform is proposed to generate bit-streams with both scalabilities. Each subband corresponds to a resolution level. Wavelet coefficients of each subband are bitplane encoded to enable quality refinement within this subband. The experimental results show the proposed coder has achieved better compression performance than that of PGC (progressive geometry compression).
