Block shuffling learning for Deepfake Detection

no code implementations6 Feb 2022 Sitong Liu, Zhichao Lian, Siqi Gu, Liang Xiao

Although the deepfake detection based on convolutional neural network has achieved good results, the detection results show that these detectors show obvious performance degradation when the input images undergo some common transformations (like resizing, blurring), which indicates that the generalization ability of the detector is insufficient.
