Image set based face recognition has recently become a popular topic as it has better performance than single image based face recognition. However, preprocessing is needed to remove the effects of some adverse conditions such as different pose angles, illumination, and expression differences within the set. One of the most effective preprocessing to improve the face recognition rate is face frontalization. Face frontalization is defined as the artificial acquisition of a face image with a different pose angle to a frontal pose. It has been observed that this process increases the face recognition performance. In this paper, image set based face recognition was performed by applying face frontalization to all images in the sets. Firstly, the faces in the IJBA database were frontalized by using the Rotate and Render hybrid frontalization method, which is based on a Three-Dimensional and Generative Adversial Network. Then, discriminative convex classifier is used for set based face recognition. In face recognition experiments, when the frontalized IJBA database and its non-frontalized version were compared, it was observed that the accuracy of face recognition increased with the frontalized face images.
