摘要 研究了一种适合在高速DSP上运行的基于小波变换的快速嵌入式零树编码(EZW)算法。通过分析传统EZW的数据压缩流程以及DSP的处理机制,对EZW算法进行了改进,使之在DSP上运行的速度得到了极大的提高,并已在某高输入数据率的图像压缩项目上使用,效果良好。 This paper research an improved fast algorithm of EZW based on wavelet transform agreeing with running on high speed DSP. The algorithm of EZW is improved through analyzing data compression flow of traditional EZW and processing method of DSP. Consequently the speed of the algorithm running on DSP is greatly enhanced and the algorithm is applied to a certain item of image compression that rate of input data is big. The result of application is very good.
