Embodiment
[0100] Such as figure 1 As shown, this embodiment provides a fake face video tampering detection method based on the time-domain self-attention mechanism. The dual-stream feature extraction module is used to extract the color features and noise features of the image space domain and then merge them, and then use the time-domain self-attention module. After extracting the time domain information of the front and back frames, and accurately predicting the tampered area, the facial intersection ratio under the calculation trust mechanism of the predicted tampered area is used to judge the true and false faces, including the network training part and the sample test part;
[0101] This embodiment takes training on the FaceForensics++ (FF++) (C0&C23) database, in-database testing on the FF++ (C0&C23) database, and cross-database testing on the TIMIT database as examples, and introduces the implementation process of this example in detail. The experiment is carried out on the Ubuntu...
