本文利用Ｂ样函数构造半正交小波基，并利用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，将其应用于遥感图象的数据压缩，取得了良好的成果
In this paper, the B-like function is used to construct the semi-orthogonal wavelet basis. The FIR filter bank with strict linear phase and exact reconstruction is designed by using the dual system. The FIR filter bank is applied to the data compression of remote sensing images and has achieved good results
