| 摘 要： | 提出了一种基于LZC算法的改进无链表小波零树编码算法,与SPIHT算法比较大大降低了所需内存容量,并在Matlab上对其进行了仿真验证,仿真结果证明PSNR值比原LZC算法提高大约1dB左右。并给出该算法基于FPGA的VLSI结构。该结构在QuartusⅡ上进行功能仿真并综合通过。

| Abstract: | This paper presents an improved listless zerotree coding algorithm.Campared with SPIAT algorithm,this algorithm,reduces the memory requirements.The algorithm is simulated and verified on Matlab.The experimental results inidicat that the PSNR results of improved LZC are about 1dB higher than those of LZC.A VLSI architecture based on FPGA is also presented,which is simulated and verified on QuartusII. |
