X-Palm: Paired Multispectral-to-Smartphone Dataset for Cross-Domain Palmprint Authentication
Researchers have introduced X-Palm, a new dataset designed to address the domain gap in palmprint authentication. This dataset includes 6,006 palm images from 103 individuals, captured in both controlled multispectral settings and unconstrained smartphone environments. Benchmarks using X-Palm reveal that current state-of-the-art models struggle with real-world variability, highlighting the dataset's utility for developing more robust cross-domain authentication systems.
