Title:
VEIN RECOGNITION METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/056974
Kind Code:
A1
Abstract:
Disclosed in the present invention are a vein recognition method and apparatus, a device, and a storage medium, comprising the following steps: respectively performing differential operation and channel connection on two target vein images to be verified, to obtain a differential image and a two-channel image of the two target vein images; performing channel connection on the obtained differential image and two-channel image to obtain a three-channel image, and taking the three-channel image as an input of a CNN network; performing finetune on a trained pre-training model SqueezeNet on ImageNet; integrating the differential image and the three-channel image by means of a cascade optimization framework to obtain a recognition result; and taking a pair of images to be verified as a sample, performing transform processing on the sample, taking a transformed sample as the input of the CNN network, and performing supervised training on the network to obtain the recognition result. The problem of less training data can be solved, and the recognition precision is also improved on the premise of small network storage capacity.
