| 摘 要： | 提出了一种指纹图特征增强与去伪的分级算法．对指纹的二值图进行增强，有效减少虚假细节点的出现；在细化图上跟踪并标记脊线，去除具有连接关系的伪细节点；利用指纹对偶性除去断点等无脊线连接关系的伪细节点．实验结果表明，此算法在去除伪细节点方面具有很好的效果，达到了自动指纹身份识别系统的实时要求．

| Abstract: | An innovational hierarchy algorithm was presented to enhance and purify fingerprint features. The binary image was enhanced. The ridges in the thinned image were traced to eliminate the false minutiae connected by ridges. Both foreground and background characteristics were used to repair ridge breaks and to eliminate islands. The experimental results show that this algorithm can detect and eliminate the spurious minutiae encountered in the thinned fingerprint image with high time efficiency. |
