小波嵌入零块编码算法 Set Partitioned Embedded bloCK ; SPECK
Bit rates in wavelet blocks are adaptively adjusted in coding process. By use of bipartition, the entropy of each wavelet block approximates to the target bit rate of one.5.
该算法首先根据每个小波块所含能量的多少和到每个小波块实际编码所用的比特数，给其分配不同的码率；然后根据二分法，通过调整各小波块的量化因子使得各小波块的熵逼近它的目标比特率。
