| Abstract: | 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. |
