Adaptive Face Forgery Detection in Cross Domain

It is necessary to develop effective face forgery detection methods with constantly evolving technologies in synthesizing realistic faces which raises serious risks on malicious face tampering. A large and growing body of literature has investigated deep learning-based approaches, especially those taking frequency clues into consideration, have achieved remarkable progress on detecting fake faces. The method based on frequency clues result in the inconsistency across frames and make the final detection result unstable even in the same deepfake video. So, these patterns are still inadequate and unstable. In addition to this, the inconsistency problem in the previous methods is significantly exacerbated due to the diversities among various forgery methods. To address this problem, we propose a novel deep learning framework for face forgery detection in cross domain. The proposed framework explores on mining the potential consistency through the correlated representations across multiple frames as well as the complementary clues from both RGB and frequency domains. We also introduce an instance discrimination module to determine the discriminative results center for each frame across the video, which is a strategy that adaptive adjust with during inference.
