变换域高斯向量嵌入融合深度特征人脸识别

TRANSFORM DOMAIN GAUSSIAN VECTOR EMBEDDING FUSION DEEP FEATURE FACE RECOGNITION

  • 摘要: 针对现有模型在识别细节信息方面的不足,提出Gabor小波变换域高斯模型向量嵌入(GGVE)人脸识别方法。该方法在Gabor变换域建立多变量高斯模型,用对数欧氏向量嵌入方法将高斯模型转换到线性空间,并利用欧氏距离进行快速计算模型的相似度。与现有的手工描述子相比,GGVE能够在复杂环境下更有效地提取出稳健的面部细节特征。为了弥补深度网络信息丢失问题,提出多特征输出的ResNet50网络模型(ResNet50MF),并结合GGVE特征进行人脸识别。实验表明,将GGVE特征和ResNet50MF高层特征进行融合能够显著提升识别准确率,可以应用于复杂环境下的人脸识别。

     

    Abstract: Aimed at the shortcomings of existing models in identifying detailed information, Gabor transform domain Gaussian model vector embedding face recognition method is proposed, called (GGVE). GGVE established a multivariate Gaussian model in the multi-scale transform domain of Gabor wavelet, and used the logarithmic-Euclidean vector embedding method to transform the Gaussian model into a linear space, and used the Euclidean distance to quickly calculate the similarity of the model. Compared with existing hand-crafted descriptors, GGVE could more effectively extract robust facial detail features in complex environments. In order to make up for the information loss of deep network, a multi-feature output ResNet50 network model (ResNet50MF) was proposed, which was combined with GGVE features for face recognition. Experiments show that the fusion of GGVE features and ResNet50MF high-level features can significantly improve the recognition accuracy, and can be applied to face recognition in complex environments.
