  14. Conclusions • The performance of our algorithm is slightly inferior to that of the 2D dynamic programming based minutiae matcher, mainly due to the inability to handle fingerprint images of very low quality. • However, integrating the proposed algorithm with the 2D dynamic programming based matching yields a better matcher.
