Abstract

With the advancement of deep neural networks (DNN), detecting falsified facial images has become a significant challenge. Previous state-of-the-art methods used fake images generated by various techniques as positive samples during the training phase. This strategy ensures that the model is exposed to a wide range of fake generation methods, resulting in a substantially higher number of positive samples than negative ones. However, in real-world scenarios, authentic images distinctly outnumber fake ones, which is not consistent with the hypothesis of designing DNN-based forensics detectors. Furthermore, the excessive use of certain fake images for training DNNs may lead to overfitting to specific fake generation techniques. Current research indicates that detectors often learn semantic features of the images, which can affect their performance. To address this issue, we propose a two-stage meta-learning feature disentanglement framework (TMFD). By leveraging the prior knowledge of meta-learning and incorporating a fine-tuning stage, extensive experimental results demonstrate that our method performs excellently across different domains.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
