Image recognition and its applications are increasingly vital in modern society. Identifying corresponding points or feature points between two images is a fundamental prerequisite and critical step for image matching. This article includes relevant images and MATLAB source code, providing a comprehensive approach to image matching using MATLAB. The implementation demonstrates key algorithms such as feature detection, descriptor extraction, and matching techniques with practical code examples.

Several fingerprint matching techniques exist, with the most widely used being: Correlation-based matching, which computes similarity across different pixel paths and rotations but suffers from high computational complexity. Feature point-based matching, the most popular technique, identifies and maps minutiae points for comparison, yet faces challenges with low-quality fingerprints. Pattern-based (image-based) matching compares fingerprint patterns (arches, whorls, loops) between templates and candidate images but requires precise alignment. Implementation considerations include algorithmic efficiency, preprocessing requirements, and reliability under varying image quality conditions.
