基于小波分析的指纹图像压缩算法

A Fingerprint Compressing Algorithm Based On The Wavelet Transform

提出了一种基于小波分析的指纹图像压缩算法,首先讨论了指纹图像的分解,然后介绍了在压缩过程中,保留指纹图像中有效细节点的零树改进算法。实验结果表明,该算法简单有效,满足实用要求。

The paper discusses a algorithm of fingerprint compressing based on the wavelet transform. Firstly, the paper analyzes the fingerprint decomposing and then introduces the zero-tree advanced algorithm which can hold the effective minutia in eouse of compressing. The experiment results show that it is simple and effective, which is to meet real requirement.
