Fingerprints Identification Using Contourlet Transform
Fingerprints Identification Using Contourlet Transform

T.M. Salman; M.K.M. Al-Azawi

Volume 35, 3A , March 2017, , Page 282-288

https://doi.org/10.30684/etj.35.3A.14

Abstract
  This paper suggests the use of contourlet transform for efficient feature extraction of fingerprints for identification purposes. Back propagated neural network is then used as a classifier. ...  Read More ...
