Foundation models show promise for face attack detection but struggle with cross-dataset transfer

By PulseAugur Editorial · [1 sources] ·

Researchers have investigated the effectiveness of foundation models for face presentation attack detection (PAD) by evaluating 24 frozen encoders using a unified linear-probing protocol. The study found that while these models contain PAD-relevant information accessible with minimal training, this information does not reliably transfer across different datasets due to domain shift. Model scale showed benefits within certain families, but performance was also influenced by architecture and pretraining methods. InternViT-6B demonstrated the lowest intra-dataset error, while CLIP ViT-B/32 offered the best cross-dataset transfer-compute trade-off among the tested probes. AI

IMPACT Investigating foundation models for face attack detection highlights the need for explicit adaptation to overcome domain shift challenges in real-world applications.

    Foundation Models for Face Presentation Attack Detection: A Unified Linear-Probing Benchmark

    arXiv:2607.26993v1 Announce Type: new Abstract: Face presentation attack detection (PAD) remains challenging under cross-dataset evaluation, where domain shift degrades models trained on a single dataset. The scarcity of large-scale labeled data motivates adapting pretrained visi…
