Noncontact Palm Vein ROI Extraction Based on Improved Lightweight HRnet in Complex Backgrounds
The extraction of ROI (region of interest) was a key step in noncontact palm vein recognition, which was crucial for the subsequent feature extraction and feature matching. A noncontact palm vein ROI extraction algorithm based on the improved HRnet for keypoints localization was proposed for dealing...
