摘要:

本文提出了一种多模态生物特征识别系统,通过高斯混合模型(GMM)的人脸和耳朵的生物特征与信念融合的估计分数特征的Gabor响应和建议的融合是由Dempster-Shafer(DS)决策理论完成。将人脸和人耳图像与Gabor小波滤波器进行卷积,提取空间增强的Gabor人脸特征和Gabor人耳特征。此外,GMM应用于高维的Gabor人脸和Gabor耳响应分别进行定量测量。利用期望最大化算法估计GMM中的密度参数。这产生了两组特征向量,然后使用Dempster-Shafer理论进行融合。实验进行了多模态数据库包含400个人的脸和耳朵的图像。研究发现,将Gabor小波滤波器与GMM和DS理论相结合,可以提供鲁棒、高效的多模态融合策略。

英文摘要:

This paper proposes a multimodal biometric system through Gaussian Mixture Model (GMM) for face and ear biometrics with belief fusion of the estimated scores characterized by Gabor responses and the proposed fusion is accomplished by Dempster-Shafer (DS) decision theory. Face and ear images are convolved with Gabor wavelet filters to extracts spatially enhanced Gabor facial features and Gabor ear features. Further, GMM is applied to the high-dimensional Gabor face and Gabor ear responses separately for quantitive measurements. Expectation Maximization (EM) algorithm is used to estimate density parameters in GMM. This produces two sets of feature vectors which are then fused using Dempster-Shafer theory. Experiments are conducted on multimodal database containing face and ear images of 400 individuals. It is found that use of Gabor wavelet filters along with GMM and DS theory can provide robust and efficient multimodal fusion strategy.
