SYSTEM FOR IRIS RECOGNITION AGAINST COUNTERFEIT ATTACK USING GRADIENT BASED FUSION OF MULTI-SPECTRAL IMAGES AND METHOD THEREOF

摘要

The present invention enables the detection of fake iris by using two or more iris images captured by multi-spectral bands, and detects fake iris by fusing the multi-spectral image of the present invention. The method includes detecting a fake iris from a captured iris image, the method comprising: obtaining and inputting an iris image including energy information through a multispectral iris imaging apparatus (S51); Detecting forgery iris primarily using energy information of the captured iris image (S52); Normalizing brightness and contrast of the multispectral iris image passing through the detection step (S53); Reconstructing the normalized multispectral iris image on a gradient basis into a single image (S54); And a recognition step (S55-S58) of discriminating forgery iris secondary by using the reconstructed iris image.;Multispectral, Iris Recognition, Image Energy, Gradient, Image Fusion
