Efficient Detection of Face Forgery Using Intra-pixel Gradient Information
摘要
With the advancement of deep learning technology, facial forgery techniques have continuously improved, and detection methods have also evolved. However, most existing approaches utilize highly complex neural networks to mitigate overfitting on a single dataset, resulting in significant computational overhead. This paper proposes a feature extraction method based on image gradients, where gradient maps in various directions are computed to capture edge information and texture features. These gradient maps are then input into a neural network for classification, reducing computational costs while minimizing the risk of overfitting to a single dataset.
