摘要
通过对常用算法改进的基础上,实现了一套完整的指纹预处理算法,包括平滑、滤波、二值化和细化,有效的利用了指纹的方向特性,很好的增强了指纹图像,保护了细节特征,为可靠、准确的实现指纹识别提供了一种可行的方法。
Based on improving of the usual algorithms, A set of algorithms for preprocessing of fingerprint images is proposed, which is composed of smoothing, filtering, binarization and thinning. The algorithm can utilize the directional characteristic of fingerprint, enhance the fingerprint images, protect minutiae feature of fingerprint.
