摘要:

生物识别系统有一些缺点:生物识别系统通常可以提供良好的性能,除了一些个人,因为它的性能高度依赖于捕获的质量。解决这些问题中的一些问题的一种解决方案是使用多生物测定,其中不同的生物测定系统组合在一起(相同生物测定模态的多次捕获、多个特征提取算法、多个生物测定模态.)。在本文中,我们感兴趣的是分数级融合函数的应用(即,我们使用多生物特征认证方案,该方案接受或拒绝申请人使用应用程序)。在现有技术中,由不同生物计量系统提供的分数的加权和(其是线性分类器)和SVM(其是非线性分类器)的使用提供了最佳性能之一。我们提出了一种新的方法的基础上使用遗传编程提供类似或更好的性能(取决于数据库的复杂性)。我们通过组装一些经典的基元函数(+,*,-,...)来获得分数融合函数。我们已经验证了所提出的方法对三个重要的生物特征基准数据集从最先进的。

英文摘要:

Biometric systems suffer from some drawbacks: a biometric system can provide in general good performances except with some individuals as its performance depends highly on the quality of the capture. One solution to solve some of these problems is to use multibiometrics where different biometric systems are combined together (multiple captures of the same biometric modality, multiple feature extraction algorithms, multiple biometric modalities...). In this paper, we are interested in score level fusion functions application (i.e., we use a multibiometric authentication scheme which accept or deny the claimant for using an application). In the state of the art, the weighted sum of scores (which is a linear classifier) and the use of an SVM (which is a non linear classifier) provided by different biometric systems provide one of the best performances. We present a new method based on the use of genetic programming giving similar or better performances (depending on the complexity of the database). We derive a score fusion function by assembling some classical primitives functions (+, *, -, ...). We have validated the proposed method on three significant biometric benchmark datasets from the state of the art.
