[0046] 1. Extraction of vein lines on the back of the hand
[0047] Hand vein texture extraction includes three parts: image segmentation, image filtering and image thinning. Among them, the image segmentation adopts the optimized repeated line tracking method proposed in the literature "Analgorithmforfinger-veinsegmentation based on modified repeated line tracking (ImagingScienceJournal, 2013)"; in the image filtering stage, the opening operation of mathematical morphology is used to filter out the noise, and then the closing operation is used to fill the holes. The window size is set to 7×7 (unit: pixel); the image refinement adopts the hit or miss transformation of math...
