摘要

我们使用BRIEF二进制局部图像描述符作为生物特征指纹数据库索引的细节描述符。具有不同描述符大小和参数化的测试在专有数据库上执行。与传统细节匹配的实现速度相比，我们发现BRIEF描述符对于数据库索引来说足够快。测试的描述符在匹配率和平均渗透率方面优于最近文献中的其他两个图像描述符(LBP, HoG)。

Fingerprint indexing via BRIEF minutia descriptors

We use BRIEF binary local image descriptors as minutia descriptors for indexing of biometric fingerprint databases. Tests with varying descriptor size and parametrisation are performed on a proprietary database. Compared with the speed of an implementation of conventional minutiae matching, we find that BRIEF descriptors are fast enough for database indexing. The tested descriptors outperform two other image descriptors (LBP, HoG) from recent literature with respect to matching rates and average penetration rates.
