This method uses B-spline interpolation to enhance missing ridge regions in fingerprint images, suggesting improved biometric recognition.
Incomplete images can reduce identification accuracy and hinder the performance of biometric recognition systems. This study proposes a method of using B-spline interpolation curve model to regenerate the incomplete fingerprint ridge regions. The image is first enhanced through a series of pre-processing steps to improve the clarity. The B-spline method is then employed to regenerate the missing ridge segments. This study aims to improve the reliability of fingerprint-based identity verification systems when dealing with degraded fingerprint images.
