Single Domain Dynamic Generalization for Iris Presentation Attack Detection

ICASSP 2023accepted

Iris presentation attack detection (PAD) has achieved great success under intra-domain settings but easily degrades on unseen domains. Conventional domain generalization methods mitigate the gap by learning domain-invariant features. However, they ignore the discriminative information in the domain-…

Few-Shot One-Class Domain Adaptation Based On Frequency For Iris Presentation Attack Detection

ICASSP 2022accepted

Iris presentation attack detection (PAD) has achieved remarkable success to ensure the reliability and security of iris recognition systems. Most existing methods exploit discriminative features in the spatial domain and report outstanding performance under intra-dataset settings. However, the degra…

Unimodal-Concentrated Loss: Fully Adaptive Label Distribution Learning for Ordinal Regression

CVPR 2022poster

Learning from a label distribution has achieved promising results on ordinal regression tasks such as facial age and head pose estimation wherein, the concept of adaptive label distribution learning (ALDL) has drawn lots of attention recently for its superiority in theory. However, compared with the…
