Learning to Detect Fake Face Images in the Wild
This addresses the issue of malicious use of GAN-generated images for tampering and personal harm, with an incremental improvement in detection accuracy.
The paper tackled the problem of detecting fake face images generated by GANs in real-world scenarios, and the result was that the proposed DeepFD method achieved a detection rate of 94.7% on images from various state-of-the-art GANs.
Although Generative Adversarial Network (GAN) can be used to generate the realistic image, improper use of these technologies brings hidden concerns. For example, GAN can be used to generate a tampered video for specific people and inappropriate events, creating images that are detrimental to a particular person, and may even affect that personal safety. In this paper, we will develop a deep forgery discriminator (DeepFD) to efficiently and effectively detect the computer-generated images. Directly learning a binary classifier is relatively tricky since it is hard to find the common discriminative features for judging the fake images generated from different GANs. To address this shortcoming, we adopt contrastive loss in seeking the typical features of the synthesized images generated by different GANs and follow by concatenating a classifier to detect such computer-generated images. Experimental results demonstrate that the proposed DeepFD successfully detected 94.7% fake images generated by several state-of-the-art GANs.
