Summary

• What is new: The new approach for detecting fake videos focuses on the novel analysis of style latent vectors and their abnormal temporal changes, leveraging the StyleGRU module enhanced by contrastive learning.
• Why this is important: The increasing sophistication in the creation of deepfake videos poses a significant challenge to detecting these fake videos, as they become more realistic and harder to distinguish from real footage.
• What the research proposes: A method using the StyleGRU module trained with contrastive learning to analyze the dynamics of style latent vectors and a style attention module that integrates these with content-based features for improved fake video detection.
• Results: The approach showed superior performance in detecting deepfakes across various benchmark scenarios, especially in cross-dataset and cross-manipulation contexts, proving the effectiveness of focusing on temporal changes of style latent vectors.
