摘要:Detection of synthetic content in portrait videos, e.g., deep fakes, is achieved.Detectors blindly utilizing deep learning are not effective in catching fake content, as
generative models produce realistic results. However, biological signals hidden in portrait videos which are neither spatially nor temporally prerved in fake content, can be ud as implicit descriptors of authenticity. 99.39% accuracy in pairwi paration is achieved.

A generalized classifier for fake content is formulated by analyzing signal transformations and corresponding feature ts. Signal maps are generated, and a CNN employed to improve the classifier for detecting synthetic content. Evaluation on veral datats produced superior detection rates against balines, independent of the source generator, or properties of available fake content. Experiments and evaluations include signals from various facial regions, under image distortions, with varying gment durations, from different generators, against unen datats, and under veral dimensionality reduction techniques.
