Abstract:Fingerprint identification is one of the most important methods of identification,and it is also the most widely used technology in the field of biometrics. In order to further improve the speed and stability of fingerprint identification system,the improved Gabor filtering algorithm can be applied. Based on this point,this paper starts with the analysis of the principle of fingerprint identification,and discusses the application of improved Gabor filter algorithm in fingerprint identification in detail. It is hoped that this study will be helpful to improve the accuracy of fingerprint identification.
Keywords:Gabor filtering algorithm;normalization processing;fingerprint recognition
