FreqMamba: Spatial–Frequency Fusion and State Space Sequence Modeling for Deepfake Detection

The rapid evolution of deepfake generation techniques has made high-fidelity facial manipulation a critical threat to social credibility and personal privacy, demanding detection algorithms with strong cross-domain generalization. Existing methods suffer from two fundamental limitations: spatial-dom...
