摘要翻译：
本文提出了一种基于高斯混合模型(GMM)的人脸和耳朵生物特征识别系统，该系统利用Dempster-Shafer(DS)决策理论对Gabor响应的估计值进行信念融合。利用Gabor小波滤波器对人脸和人耳图像进行卷积，提取空间增强的Gabor人脸特征和Gabor人耳特征。此外，将GMM分别应用于高维Gabor人脸和Gabor耳响应，进行定量测量。在GMM中采用期望最大化(EM)算法估计密度参数。这产生了两组特征向量，然后使用Dempster-Shafer理论进行融合。实验在包含400个个体的人脸和耳朵图像的多模态数据库上进行。研究发现，利用Gabor小波滤波器结合GMM和DS理论可以提供鲁棒有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.
