Abstract: The algorithm of fingerprint feature extraction using Gabor filterbank was
proposed in order to overcome the drawback of traditional minutiae feature
extraction. Through studying texture structure information of fingerprint ridges
and applying Gabor filterbank to texture, a physical model of Gabor filtering
was established. A quick and simple method of center point searching was
presented, according to center point's position round grid feature area was
located, filtering by eight directions of Gabor filterbank and feature extraction.
The result of comparison experiment showed validity of Gaborbased.
