OpenCV-Based Finger Vein Image Matching: Techniques and Workflow

This article explains the principles of first‑generation biometrics, introduces finger‑vein recognition as a more secure alternative, and details a complete OpenCV workflow—including Gaussian smoothing, histogram equalization, edge detection, SIFT feature extraction, and knnMatch—to preprocess and match finger‑vein images.
