Fingerprint Enhancement

Fingerprint enhancement aims to improve the quality of degraded or incomplete fingerprints, crucial for accurate biometric identification in forensic science and security applications. Current research heavily utilizes deep learning architectures, such as U-Net and Generative Adversarial Networks (GANs), often incorporating multi-task learning to simultaneously enhance ridge patterns and predict minutiae points – key features for fingerprint matching. These advancements focus on improving both the accuracy and speed of enhancement, leveraging techniques like wavelet transforms and GPU optimization to process fingerprints more efficiently. The resulting improvements in fingerprint recognition accuracy have significant implications for forensic investigations and broader biometric security systems.
