Abstract Based on the analysis of GPL principal curve algorithm and the specialties of fingerprint, the principal curve is used to reflect the structure of fingerprint. The original GPL principal curve algorithm is improved to get better skeletonization of fingerprint and the minutiae extraction based on the principal curves is applied. The experimental results show that the improved principal curve algorithm is more efficient and its skeletonization is much better than those of the original ones. The accuracy of minutiae extraction based on the principal curves is also higher than some traditional methods, which has higher value in application.
