摘　　要：双正交小波变换应用较广泛。其特点是FIR滤波器具有线性相位 ,滤波器系数具有对称性 ,可避免产生信号失真。本文分析了双正交小波变换图像处理方面的性能和特点 。Biorthogonal wavelet transform was applied extensively. The specialty of its filter possesses linearity phase and coefficient of its filter possesses symmetry. So, distortion of signal can be avoided in procession. In this paper, the performance and the specialty which biorthogonal wavelet transform has in image procession was analyzed, and the application of fingerprint image compression was introduced.
