摘要 本文提出了一种基于整数提升小波正变换的改进的多级树集合分裂算法,减少了对内存反复读取的操作,减轻了对内存造成的负担,提高了编码的效率。 In this paper,a improved SPIHT algorithm based on int lifting wavelet correct transform is proposed for the shortcomings of SPIHT.It reduces the reading operations to memory and the burden of memory by the process and improves the efficiency of the coding.
