Abstract:

In the process of automatic fingerprint identification, fingerprint image enhancement plays a key role. Based on the texture
characteristics of fingerprint ridges and Gabor filter's quality in directivity and frequency selectivity, the application of Gabor filter in
fingerprint enhancement algorithm is studied and the results show that it can improve the efficiency of automatic fingerprint
identification.

Key words: fingerprint characteristics, image enhancement, algorithm
