An Improved Set Partitioning in Hierarchical Trees

Abstract

Abstract: By studying on set partitioning in hierarchical trees (SPIHT), and analyzing the distribution of the image wavelet coefficients, this paper presents that there is redundancy in the SPIHT coding stream. So an improved SPIHT coding method is proposed, its efficiency is proved from theory analysis and simulation results.

摘要： 通过对等级树集分割编码方法的研究及对图像小波系数的分布特征的分析，发现等级树集分割编码码流还存在一些冗余。基于此提出了一种优化的等级树集分割编码方法，理论分析和仿真实验证明了该方法的有效性。
