Abstract EN
Face identification aims at putting a label on an unknown face with respect to some training set.
Unconstrained face identification is a challenging problem because of the possible variations in face pose, illumination, occlusion, and facial expression.
This paper presents an unconstrained face identification method based on face frontalization and learning-based data representation.
Firstly, the frontal views of unconstrained face images are automatically generated by using a single, unchanged 3D face model.
Then, we crop the face relevant regions of the frontal views to segment faces from the backgrounds.
At last, to enhance the discriminative capability of the coding vectors, a support vector-guided dictionary learning (SVGDL) model is applied to adaptively assign different weights to different pairs of coding vectors.
The performance of the proposed method FSVGDL (frontalization-based support vector guided dictionary learning) is evaluated on the Labeled Faces in the wild (LFW) database.
After decision fusion, the identification accuracy yields 97.17% when using 7 images per individual for training and 3 images per individual for testing with 158 classes in total.
