Abstract:	Matching contactless fingerprint images with traditional contact-based impressions has become increasingly important, especially due to the COVID-19 pandemic. Contactless methods provide better hygiene and benefit from the availability of affordable mobile phones capable of capturing high-resolution fingerprints. Traditional minutiae-based matching techniques are susceptible to errors caused by false or missing minutiae points in low-quality images, emphasizing the need for alternative features. This study explores the magnitude spectrum, a feature derived from the Discrete Fourier Transform (DFT) for matching contactless and contact-based fingerprints. A 256-bin histogram of the magnitude spectrum is generated to estimate the correlation distance to distinguish genuine from imposter attempts. Using this dataset, a Support Vector Machine (SVM) model is carefully trained and tested through 10-fold cross-validation. The results demonstrate a high matching accuracy of 97.97%, with an Equal Error Rate (EER) of 2.02% and a Rank 1 accuracy of 93.38%. The SVM classifier also achieves 96.96% accuracy in differentiating between 'genuine' and 'imposter' classes. [ABSTRACT FROM AUTHOR]
