5. Joint Face Alignment and 3D Face Reconstruction with Application to Face Recognition.

Abstract

Face alignment and 3D face reconstruction are traditionally accomplished as separated tasks. By exploring the strong correlation between 2D landmarks and 3D shapes, in contrast, we propose a joint face alignment and 3D face reconstruction method to simultaneously solve these two problems for 2D face images of arbitrary poses and expressions. This method, based on a summation model of 3D faces and cascaded regression in 2D and 3D shape spaces, iteratively and alternately applies two cascaded regressors, one for updating 2D landmarks and the other for 3D shape. The 3D shape and the landmarks are correlated via a 3D-to-2D mapping matrix, which is updated in each iteration to refine the location and visibility of 2D landmarks. Unlike existing methods, the proposed method can fully automatically generate both pose-and-expression-normalized (PEN) and expressive 3D faces and localize both visible and invisible 2D landmarks. Based on the PEN 3D faces, we devise a method to enhance face recognition accuracy across poses and expressions. Both linear and nonlinear implementations of the proposed method are presented and evaluated in this paper. Extensive experiments show that the proposed method can achieve the state-of-the-art accuracy in both face alignment and 3D face reconstruction, and benefit face recognition owing to its reconstructed PEN 3D face.

6. Combined training strategy for low‐resolution face recognition with limited application‐specific data.

Author

Zeng, Dan, Spreeuwers, Luuk, Veldhuis, Raymond, and Zhao, Qijun

Abstract

Application‐specific data for certain biometric applications are often not sufficiently available. The authors present a solution for face recognition with limited application‐specific data. Existing methods often use a classifier with convolutional neural networks (CNNs) as feature extractors. The CNNs are trained with massive general (i.e. not application specific) data and the classifier is trained with application‐specific data. Alternatively, the authors propose a combined training strategy to train the classifier on a balanced mixture of general and application‐specific data, such that the recognition performance is maximised. The proposed method largely alleviates the needs for application‐specific data. To prove its effectiveness, they apply the proposed method to low‐resolution face recognition. Specifically, they use the heterogeneous joint Bayesian (HJB) classifier that is capable of comparing features from the same modality but with different characteristics. To further boost performance, the authors augment the training data by pre‐processing it to resemble application‐specific data. They conducted extensive experiments on challenging datasets, namely, SCface and COX. The results show that the proposed method improves the true match rate on SCface at a false match rate of 10% by ∼11% and the true match rate on COX at a false match rate of 1% by ∼12%.

Abstract

Abstract: In this paper, we introduce a novel linear discriminant approach called Two-Dimensional Neighborhood Margin and Variation Embedding (2DNMVE), which explicitly considers the modes of variability among nearby images and the discriminating information. To be specific, we construct an adjacency graph to model the intra-class variation, which characterizes the modes of variability of the face images, of the values of face images from the same class, and inter-class variation which encodes the discriminating information, and then incorporate the modes of variability and discriminating information into the objective function of dimensionality reduction. Thus, 2DNMVE is robust to intra-class variation and has better generalization capability on testing data. Experiments on four face databases show the effectiveness of the proposed approach.
