Self-Supervised Face Image Manipulation by Conditioning GAN on Face Decomposition

Abstract

We present a novel architecture for manipulating facial expressions, head poses, and lighting conditions from a single monocular image. Recent methods based on Generative Adversarial Networks show promising results in expression manipulation. However, the variation is either defined by a limited number of classes or not well suitable for explicit manipulation of different attributes such as pose and lighting conditions. Besides, state-of-the-art methods are mostly focused on frontal faces. Therefore, in this paper, a new Generative Adversarial Network architecture is proposed by explicitly conditioning on the appearance image space which is the product of direct manipulation of facial expressions, light and pose conditions of the face model in 3D space. In addition, the method only requires video sequences for training. Therefore, it is self-supervised. Unlike other face manipulation methods, the proposed method does not require target specific training. Large scale experiments show that our method outperforms state-of-the-art methods for different scenarios.
