Fingerprint identification using feature extraction: A survey

A literature survey of some techniques used to extract features of a fingerprint as well as matching them with the database is specified in this paper. Some of the surveyed research papers have used traditional procedures such as identification techniques and verification techniques, whereas the other articles have used novel methods. To design and develop a fingerprint feature extraction method and to match them using pixel details, first of all fingerprints of good quality are acquired using a high resolution scanner. Image enhancement and thinning could be done. Finally features are extracted and estimated. These estimated features are used to match with the template database using pixel based matching algorithm. The features are unique, which allow a single feature to be suitably matched with high possibility against a large database of features.
