摘要

本文介绍了MPEG-4国际标准所采用的视觉纹理压缩方案。该方案基于多尺度零树小波熵编码(MZTE)技术的概念，在空间分辨率或图像质量方面提供不同级别的可扩展性层。MZTE提供了大大改进的压缩效率和精细渐进的可扩展性。在MPEG4视频组和SNHC组中，视觉纹理编码配置文件均采用MZTE方案作为基线技术。

Multi-scale zerotree entropy coding

This paper describes the visual texture compression scheme adopted for MPEG-4 international standard. The scheme is based on the concept of multiscale zerotree wavelet entropy coding (MZTE) technique that provides different levels of scalability layer in terms of either spatial resolutions or picture quality. MZTE provides much improved compression efficiency and fine-gradual scalabilities. The MZTE scheme is adopted as the baseline technique for the visual texture coding profile in both MPEG4 video group and SNHC group.
