Robust Finger-vein ROI Localization Based on the 3<i>σ</i> Criterion Dynamic Threshold Strategy

Region of interest (ROI) localization is one of the key preprocessing technologies for a finger-vein identification system, so an effective ROI definition can improve the matching accuracy. However, due to the impact of uneven illumination, equipment noise, as well as the distortion of finger positi...
