摘要
提出了一种基于双正交小波分解的静态图像压缩编码方法,将图像作3次小波分解后,对低频变换系数作DPCM编码,对高频变换系数采用游程编码。实验证明这是一种比较有效的编码方法。
篒n this paper, an image compression encoding method based on biothogonal wavelet transformationis presented. After the image data is decomposed for three times, the low frequency subband coefficients are processed using DPCM and the high frequency subband coefficients are processed using RLC. Expremetal result showsthat this method is available.
