The Analysis And Research For Key Algorithm Of Fingerprint Identification

Fingerprint recognition technology has entered into a special stage, people use fingerprint recognition technology to do more and more, while it also required to have a new fingerprint recognition technology breakthrough. Fingerprint image preprocessing fingerprint image enhancement is a very important part, but also in identifying where the most waste of time, and if this link optimization, will greatly shorten the fingerprint identification process will also enhance the fingerprint feature extraction and matching success Rate. This article lists several existing algorithms, their analysis one by one, obtained its prominent feature in the algorithm, summed up the shortcomings and inadequacies in the algorithm, and algorithm and the advantages of combining some improvement ideas.
