摘要
预处理是指纹自动识别过程中的第一步，它的好坏直接影响着指纹自动识别系统的效果．文中分灰度去噪、二值化、二值滤波去噪、细化等几部分．详细介绍了指纹自动识别系统中的预处理技术，文中所介绍的算法都是经实践证明并取得了很好效果的，具有很高的使用及参考价值．
Preprocessing is the first step of fingerprint identification system, and it influences the result of fingerprint identification directly. The preprocessing in an automatic fingerprint identification system is presented in four parts:filtration in gray image, binaryzation, filtration in binary image, and thinning. The algorithms introduced here have all been checked in practice and have good result, to that they have high value both in practice and in reference.
