Researchers have introduced AGVBench, a new benchmark designed to evaluate data augmentation strategies for vein recognition systems. The benchmark tested 30 augmentation methods across seven different model architectures on public palm- and finger-vein datasets. Findings indicate that multi-image mixing techniques like MixUp and PuzzleMix offer the best recognition performance but suffer from poor calibration and adversarial vulnerability. The study also highlights that severe geometric transformations can degrade recognition accuracy, and augmentation effectiveness differs between palm and finger vein datasets, underscoring the need for reliability-oriented evaluations beyond simple accuracy.
