Abstract:

Because face forensics has great harm, the research on the discrimination method of face forensics is very important. The current researches on face forensics detection based on convolutional neural networks have made some progress, but the detection results are not satisfactory. Most of the existing methods focus only on a certain kind of features of the fake face, and the methods of face forensics are becoming more and more diverse, which is the main reason for the poor robustness of the discrimination result. Aiming at these problems, the proposed method exploits an excellent pre-trained model and a data augmentation method as well as a label smoothing loss function, achieving significant accuracy improvement in detection of face forensics videos. Due to the processing of frame extraction, the proposed method has high computational efficiency.
