[0143] (1) The collection and labeling of finger vein images are as follows:
[0144] The images in the sample set are from the "Spoofing-Attack Finger Vein Database" (https: / / www.idiap.ch / dataset / fvspoofingattack) of the Idiap Institute in Switzerland. The real and fake finger vein images in this database come from 440 images generated by 110 people, and the left and right index fingers of each person are collected twice, resulting in a total of 880 vein images. This is divided into three parts, namely, training set, verification set, and test set. Among them, there are 120 real and fake finger vein images in the training set, a total of 240, and there are 120 real and fake finger vein images in the verification set, a total of 240. The collection contains a total of 400 real and fake finger vein images, each with a size of 150*565 pixels. The training set is used to train the DBN model and the BP neural network model, the verification set is used for threshold estimation, a...
