摘　　要：近来指纹识别系统(AFIS)在很多领域中得到了广泛的应用。人们对指纹识别算法的研究也日渐增多。提出了一种适用于实时指纹识别系统的特征点匹配算法。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AnilJain和XipingLuo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,我们的算法速度更快,精度更高,更适用于实时指纹识别系统。AFIS(automatic fingerprint identification system) has been widely used in many areas in recent years.The studies of fingerprint identification algorithms increased greatly at the same time.A new fingerprint minutiae matching algorithm is proposed for real time AFIS.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.
