Noncontact Palm Vein ROI Extraction Based on Improved Lightweight HRnet in Complex Backgrounds

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...
