SFAD-Net: A Dual-Stream Spatial–Frequency Attention Network for Fingerprint Presentation Attack Detection

Fingerprint presentation attack detection (PAD) remains an open problem owing to continually developing spoofing schemes and large variations in sensors and acquisition conditions. In this paper, we propose SFAD-Net, a lightweight dual-stream spatial–frequency attention network for fingerprint presentation attack detec...
