摘　　要：近年来,文献中报道了许多指纹匹配算法,它们各有不同的特点。提出一种新的指纹特征点匹配算法,通过指纹特征点匹配来实现指纹图像的匹配。这种算法通过采用圆形匹配限制框和简化计算步骤等方法,优化了Anil Jain和Xiping Luo等人的算法。对一组由扫描仪获取的指纹图像做实验,结果表明,该算法速度更快,精度更高,更适用于实时指纹识别系统。Many fingerprint matching algorithms have been reported in recent years, which have different features. It is proposed a new fingerprint minutiae matching algorithm and done fingerprint images matching through minutiae matching. This algorithm optimized Anil Jain et al.'s and Xiping Luo et al.'s algorithms by simplifying the calculating process and using a round bounding box. Experiments done on a set of fingerprint images captured with a scanner showed that our algorithm is faster, more accurate and more suitable for the real time fingerprint identification system.
