Fingerprint matching algorithm based on discrete to continuous approach

Matching is a key operation in the current fingerprint system. The objective of fingerprint matching is to achieve a high reliability in comparing two fingerprint details. The large variability in different impressions of the same finger makes reliable matching fingerprint an extremely difficult problem. In this paper, a minutiae-based algorithm for fingerprint pattern recognition and matching is proposed, based on discrete to continuous approach, which is essentially a point pattern matching approach. By transforming this discrete problem to a continuous problem, the experimental results of the proposed algorithm demonstrate efficient recognition and matching performance compared with several minutiae based algorithms.
