摘 要 随着生物识别技术的不断进展，人们发现每个人的指纹具有唯一性和不变性。因此指纹识别技术逐步进展为一种新的身份识别方式，并且凭借其良好的安全可靠性，大有取代传统身份识别方式的趋势。本文简要介绍了指纹识别的基本步骤，分别是指纹图像预处理、指纹特征提取、指纹匹配。在图像预处理中，依次介绍了规格化处理、图像增强、二值化处理和细化处理的方法。预处理后将得到一幅宽度为一个像素的细化二值图像，然后通过特定的端点和交叉点的特征进行指纹匹配。论文中采纳 MATLAB 编程实现全部算法。关键词：指纹识别，图像处理，特征提取，特征匹配AbstractWith the continuous development of Biometric Identification Technology,People found that each person's fingerprint has uniqueness and invariant.Therefore Fingerprint Identification Technology gradually developed as a new identity recognition mode，and with its good safety and reliability，it has replaced the traditional identification way trends. This paper briefly introduces the basic step of Fingerprint Identification，they are Fingerprint image preprocessing, Fingerprint characteristic extraction,Fingerprint matching.In the Fingerprint image preprocessing,in turn introduced the normalized processing, Image enhancement, Binary treatment and Refining processing method.After pretreatment will get a picture for a pixel width of twenty-first-century binary image,then through the particular endpoint and intersection on the characteristics of the Fingerprint matching.This paper using Matlab programs all algorithm.Key words Fingerprint identification Image processing Feature extraction Feature matching毕业设计（论文）原创性声明和使用授权说明原创性声明本人郑重承诺：所呈交的毕业设计（论文），是我个人在指导老师的指导下进行的讨论工作及取得的成果。尽我所知，除文中特别加以标注和致谢的地方外，不包含其他人或组织已经发表或公布过的讨论成果，也不包含我为获得 及其它教育机构的学位或学历而使用过的材料。对本讨论提供过帮助和做出过贡献的个人或集体，均已...
