Without lists,the memory requirement is reduced significantly,and the improved listless zerotree coding method enhances the coding speed by improving the zerotree coding process,and reduces the complexity in the encoding and decoding procedure.
本文对SPIHT算法进行了改进 ,得到一种在编码和解码过程中都不用链表的小波零树编码方法 ,称为改进的无表零树编码 。
