研究了遥感图像数据压缩新技术。利用半正交小波基和对偶系设计了具有严格线性相位和精确重建特性的ＦＩＲ滤波器组，将其应用于遥感图像的数据压缩，取得了良好的成果。
Research on remote sensing image data compression technology. FIR filter banks with strict linear phase and exact reconstruction are designed by using semi-orthogonal wavelet bases and dual systems. The FIR filter banks are applied to the data compression of remote sensing images and achieved good results.
