| 摘 要： | 指纹图像经预处理后，由于各种原因，会产生数以百计的特征。为了图像匹配的精确和快速，提出一套在细化后的指纹点线图上提取细节特征并对其剪枝的方法，并根据细节特征的拓扑特性，设计了验证其可靠性的算法。通过实验，证明了该后处理过程在去除指纹图像伪特征方法面具有良好的效果。

| Abstract: | After pre-processing of the fingerprint image, hundreds of characteristics will be produced for varieties of reasons. In order to realize accurate and quick image matching, a set of methods for extracting and pruning of details on the subdivided fingerprint point and line diagram are proposed. An algorithm for verifying their reliability is designed according to the topological property of the details. The experiments prove that the post-processing process has good effects for eliminating pseudo-characteristics of fingerprint image. |
