In recent years, DeepFake has become a public concern due to the abuse of advanced generative adversarial networks (GANs). Researchers have proposed various approaches to fight against DeepFakes by identifying whether an image or video is synthesized by GANs. Due to the imperfect design of GANs, the introduced artifacts serve as a promising clue for detection, which is captured by many proposed methods. However, these methods failed in presenting the artifacts in an interpretable manner. In this paper, we propose a novel approach by focusing on the artifact regions with dual attention (channel attention and spatial attention) to localize the observable and invisible artifacts for assisting DeepFake detection. Specifically, our proposed approach is agnostic to the specific backbone, which could be easily plugged into any DNN models to improve their performance. Experimental results show that our proposed dual attention could be deployed in any DNN based classifiers to improve their performance in detecting various DeepFakes. The detection accuracy on six current open-source DeepFake datasets is improved by 3.50%, 2.56%, 1.64%, 1.36%, and 0.89% in average on MesoNet, Meso-Inception, VGG-19, Xception, and EfficientNet, respectively. Besides, experimental results also show that our attention mechanism can serve as an asset for pixel-wise manipulation localization. |
