摘要
针对图像数据在二维小波变换后多辨率塔形结构的小波系数的特点，提出了适应数据特点的处理技术和压缩方法。大幅度地降低了图像数据间的冗余度，取得了较好的压缩效果。
Regarding to the feature of the multiresolution pyramid structure wavelet coefficients resultedho 2 - D wavelettransform,in this paper procesaing technology and code method are introduced adapting tothe data structure. It fully reduces the relations among image data,and obtains good compression effect.
