SPIHT algorithm is an embedded zerotree coding algorithm known for its high performance. However, it needs a large number of memories and many repeated calculations, so it is more complicated, and can′t implement real-time compression.
SPIHT算法是一种简单、有效的嵌入式零树编码算法,但是,它需要大量存储空间,而且存在多次重复运算,因而复杂程度高,时间消耗大,不利于实时压缩。
