基于第二代Curvelet变换的指纹预处理算法

Algorithm of fingerprint preprocessing based on the second generation curvelet transform

分析了现有的一些增强、分割算法的不足,提出了基于第二代Curvelet变换的指纹图像预处理算法.实验结果表明提出的算法简单有效,能够实现指纹图像增强的要求.

An algorithm for the enhancement of fingerprints was presented; an algorithm for realizing the foreground/background segmentation was also discussed, based on a new mathematical transform, namely, the second generation curvelet transform. The result shows that the algorithm is effective and the transform is attractive.
