SSAN: A Novel Dual‑Stream Network for Domain‑Generalized Face Anti‑Spoofing

This paper proposes SSAN, a novel dual‑stream network that separates content and style features to achieve domain‑generalized face anti‑spoofing, employing adversarial learning for content, contrastive learning for style, and a large‑scale evaluation protocol across twelve public datasets, achieving state‑of‑the‑art performance.
