摘要
对在指纹的预处理和特征提取、指纹分类、指纹的匹配过程中的方向图、滤波器、神经网络等关键性原理和技术做了详细的说明,并对在各个过程中用到的方法做了进一步的比较,讨论了各种方法的优越性。
Details the key theory and techniques,such as directional image,filter and neural network,which are widely used in the process of fingerprint image preprocessing and feature extraction,classification and matching.The paper compares these methods in every step of this process,and discusses the superiorities and shortcomings of all the techniques.
