MATLAB-Based Fingerprint Recognition System

This article presents a MATLAB-based fingerprint recognition system comprising both image datasets and executable code. To operate the system, users must first set the current directory as the working directory in MATLAB, then enter the command 'fpextractdemo' in the command line to initiate the fingerprint recognition process. The system incorporates preprocessing algorithms to enhance recognition accuracy, including noise reduction filters and contrast enhancement techniques that improve image quality before feature extraction. The core implementation utilizes feature extraction algorithms (likely minutiae-based) and pattern matching methods for identification. Additionally, the modular code structure allows for customization and secondary development to adapt the system to various application scenarios. The article aims to facilitate better understanding and practical implementation of fingerprint recognition technology through this MATLAB demonstration.
