论文摘要
近年来,由于深度学习的出现,面部识别取得了出色的成功。但是,与额叶面孔相比,这些深度识别模型中的许多在处理曲线面的表现相对较差。这种表现不佳的主要原因是,学习对概况识别有用的大型姿势不变的深度表示本质上很难。在本文中,我们假设轮廓面域与深度特征空间中的额面域具有逐渐连接。我们希望通过将轮廓面和额叶面向共同的潜在空间投影并在潜在领域进行验证或检索来利用这种连接。我们利用耦合的生成对抗网络(CPGAN)结构在潜在的常见嵌入子空间中找到配置文件和额叶图像之间的隐藏关系。具体而言,CPGAN框架由两个基于GAN的子网络组成,一个用于额叶域,另一个专用于配置文件域。每个子网络都倾向于找到一个投影,该投影最大化了一个普通嵌入特征子空间中两个特征域之间的成对相关性。使用CFP,CMU Multipie,IJB-A和IJB-C数据集证明了与最新方法相比,我们的方法的功效。
In recent years, due to the emergence of deep learning, face recognition has achieved exceptional success. However, many of these deep face recognition models perform relatively poorly in handling profile faces compared to frontal faces. The major reason for this poor performance is that it is inherently difficult to learn large pose invariant deep representations that are useful for profile face recognition. In this paper, we hypothesize that the profile face domain possesses a gradual connection with the frontal face domain in the deep feature space. We look to exploit this connection by projecting the profile faces and frontal faces into a common latent space and perform verification or retrieval in the latent domain. We leverage a coupled generative adversarial network (cpGAN) structure to find the hidden relationship between the profile and frontal images in a latent common embedding subspace. Specifically, the cpGAN framework consists of two GAN-based sub-networks, one dedicated to the frontal domain and the other dedicated to the profile domain. Each sub-network tends to find a projection that maximizes the pair-wise correlation between two feature domains in a common embedding feature subspace. The efficacy of our approach compared with the state-of-the-art is demonstrated using the CFP, CMU MultiPIE, IJB-A, and IJB-C datasets.
