摘　　要：指纹检测技术作为一种身份识别技术,具有很高的方便性、安全性和准确性。本文通过数码相机获取指纹图像,由于采集到的图像每次捺印的方位不完全一样,着力点不同会带来不同程度的变形,又存在大量模糊指纹,如何正确提取特征和实现正确匹配,是指纹识别技术的关键。本文将采集到的图像运用MATLAB软件进行图像处理,通过图像增强、图像压缩、特征提取等方法,获得指纹特征信息,结果表明,利用MATLAB软件的图像处理功能,有助于提高指纹检测时对特征点的分辨能力。Fingerprint detection technologies as an identification,high with convenience,security and accuracy,we can twain the fingerprint image by Digital camera.By reason of the image each press the direction is partly the same,the different acting point can bring inordinately modification,and in existence scores of fingerprint image,how to fetch the hallmark for right and implement matching for right,is the crucial for Fingerprint detection technologies.Using image processing software dispose of the image,through image enhancement,image compression,feature extraction methods and other methods,fingerprint access to information,and compression storage,comparison of feature points.The results show that the use of matlab software,image processing functions,help to improve the characteristics of fingerprint detection point on the ability to distinguish.
