摘要

SPIHT是一种非常有效的图像压缩算法，它基于小波系数编码组为零树的思想。这种方法很适合于父子关系容易建立的二进小波变换。本文研究了SPIHT算法如何用于任意小波包基。

Modified SPIHT algorithm for wavelet packet image coding

SPIHT is a very efficient image compression algorithm that is based on the idea of coding groups of wavelet coefficients as zerotrees. This method is well suited for the dyadic wavelet transform, where child-parent relations are easily established. In this paper we investigate how the SPIHT algorithm can be used for any arbitrary wavelet packet basis.
