针对传统小波变换过程复杂的缺点和SPIHT 算法编码过程重复运算、存储量大的问题。首先分析了小波基
和小波分解层数的选取, 然后提出了一种改进的SPIH T 算法, 该算法利用可变阈值对SPIH T 算法中初始子带进行分类得
到一种更有效的编码算法。-Against disadvantages of traditional process of complex wavelet transform and SPIHT algorithm coding process repeated operation, the problem of large storage capacity. First analyzed the wavelet base
And the selection of the layer number of wavelet decomposition, and then puts forward an improved SPIH T algorithm, the algorithm with variable threshold for SPIH T be initial subband classification algorithm
To a more efficient coding algorithm.
