The field of face recognition (FR) has witnessed great progress with the surge of deep learning. Existing methods mainly focus on extracting discriminative features, and directly compute the cosine or L2 distance by the point-to-point way without considering the context information. In this study, we make a key observation that the local con-text represented by the similarities between the instance and its inter-class neighbors1plays an important role forFR. Specifically, we attempt to incorporate the local in-formation in the feature space into the metric, and pro-pose a unified framework calledInter-class DiscrepancyAlignment(IDA), with two dedicated modules, Discrepancy Alignment Operator(IDA-DAO) andSupport Set Estimation(IDA-SSE). IDA-DAO is used to align the similarity scores considering the discrepancy between the images and its neighbors, which is defined by adaptive support sets on the hypersphere. For practical inference, it is difficult to acquire support set during online inference. IDA-SSE can provide convincing inter-class neighbors by introducing virtual candidate images generated with GAN. Further-more, we propose the learnable IDA-SSE, which can implicitly give estimation without the need of any other images in the evaluation process. The proposed IDA can be incorporated into existing FR systems seamlessly and efficiently. Extensive experiments demonstrate that this frame-work can 1) significantly improve the accuracy, and 2) make the model robust to the face images of various distributions.Without bells and whistles, our method achieves state-of-the-art performance on multiple standard FR benchmarks.

年龄不变人脸识别的研究越来越受到人们的关注。然而,匹配年龄差距较大的人脸仍然是一个具有挑战性的问题,主要是由于衰老引起的人脸外观显着差异。为了减少这种差异,在本文中,我们提出了一种新的算法,以消除与年龄相关的组件混合的身份和年龄信息的功能。具体来说,我们将混合人脸特征分解为两个不相关的分量:身份相关分量和年龄相关分量,其中身份相关分量包含对人脸识别有用的信息。为了实现这一想法,我们提出了去相关对抗学习(DAL)算法,其中引入了一个规范映射模块(CMM)来寻找骨干网络生成的配对特征之间的最大相关性,而骨干网络和因子分解模块被训练来生成减少相关性的特征。因此,所提出的模型学习年龄和身份的分解特征,其相关性显着降低。同时,身份相关特征和年龄相关特征分别由身份和年龄保持信号监督,以确保它们都包含正确的信息。在流行的公共领域人脸老化数据集(FG-NET,MORPH Album 2和CACD-VS)上进行了广泛的实验,以证明所提出的方法的有效性。

随着年龄的增长,人脸的外观会发生显著的类内变化,因此年龄不变人脸识别(AIFR)仍然是人脸识别领域的一个主要挑战。为了减少由年龄引起的类内差异,在本文中,我们提出了一种新的方法(即正交嵌入CNN,或OE-CNN)来学习年龄不变的深层人脸特征。具体来说,我们将深层人脸特征分解为两个正交分量来表示年龄相关和身份相关的特征。因此,对老化具有鲁棒性的身份相关特征随后用于AIFR。此外,为了补充现有的跨年龄人脸数据集,推进该领域的研究,我们构建了一个全新的大规模跨年龄人脸数据集(CAF)。在三个公共领域人脸老化数据集(MORPH Album 2、CACD-VS和FG-NET)上进行的大量实验表明了所提出方法的有效性和所构建的CAF数据集在AIFR上的价值。在最流行的通用人脸识别(GFR)数据集LFW上对我们的算法进行基准测试,还证明了GFR的泛化性能。
