针对传统身份识别方法中标识物体容易丢失和伪造的问题，在对比可作为识别特征的多种生物特征的基础上，提出并实现了一种基于指纹特征的识别系统。系统首先利用指纹采集器获取指纹图像，然后对采集到的指纹图像进行包括图像分割、图像增强、图像二值化和图像细化在内的图像预处理操作，接着对处理过后的指纹图像进行指纹的特征提取，最后将提取到的待验证手指指纹特征，与指纹特征库中的候选指纹特征进行匹配，以实现用户身份识别。实验结果表明，基于指纹特征的识别系统具有很高的实时性和较高的准确性，可以满足一般用户的身份识别要求。

Aiming at the identification objects easily lost or forgery in traditional identification methods,based on series of biological iden-tification characteristics,propose and realize a recognition system based on fingerprint characteristic. First,the system obtains the finger-print image using fingerprint collector,then carry out the image pre-processing for the collected fingerprint image,inclusive of image seg-mentation,image enhancement,image binarization and image thinning,and then the system will extract the fingerprint characteristic for the treated fingerprint image,finally the extracted fingerprint features are mapped with the candidate fingerprint features in the fingerprint feature base to realize the user identity identification. Experimental results show the recognition system based on fingerprint feature has good accuracy and high real-time performance,which can meet the requirements of general recognition .
