摘　　要：为了将指纹纹理中的有效信息提取出来,通过指纹图像预处理和特征点提取两个步骤,提出了一种指纹图像的特征点提取算法。图像预处理主要包含图像增强、二值化、细化,而特征点提取则采用模板搜索提取法。最终通过MATLAB GUI系统将采集的指纹图像进行处理,在用户界面内显示图像处理结果以及特征点提取结果,说明该设计很好地实现了算法目的,并且具有很好的稳定性和扩展性。In order to extract the effective information from the fingerprint texture,through the preprocessing of fingerprint image and the extraction of feature points,this paper proposes a algorithm to extract the feature points of fingerprint image.Image preprocessing mainly includes image enhancement,binarization,thinning,and using template,it searches the feature points.Finally through MATLAB GUI system to process the fingerprint image acquisition,and display results and feature point extraction in the user interface,the result shows that the design reaches the purpose very well,and has good stability and extensibility.
