Guihua Tang, Lei Sun, Xiuqing Mao · 2020
Generative adversary networks (GAN) have recently led to highly realistic synthesized image. For the current GAN-synthesized faces detection methods exist false prediction if the real faces with angles or occlusion. This paper proposes a GAN-synthesized faces detection method based on Deep Alignment Network (DAN), which improve prediction accuracy of real faces by makes the locations of facial landmark points more precise. Our method first uses DAN to obtain the locations of facial landmark points of real and synthesized faces; then the landmark points are converted into feature vectors by principal component analysis (PCA); finally, input feature vectors to the constructed Support Vector Machine (SVM)classifier for training. Experimental results show that our method achieves better performance than other method under face with angles or occlusion.
