易于硬件实现的无链表小波零树编码算法
Listless wavelet zerotree coding algorithm for hardware implementation
摘要
Abstract
A listless minimum zerotree coding algorithm (LMZC) based on thefast lifting wavelet transform with lower memory requirement and higher compression performance is presented. A minimum zerotree of wavelet coefficients and a listless significance map coding algorithm using a new scanning order and new flag maps different from LZC are utilized. A comparison reveals that the PSNR results of LMZC are up to 0.5 dB higher than those of LZC, and the compression performance of LMZC outperforms that of SPIHT in terms of hardware implementation.关键词
