Claim 0:
1. A finger vein comparison method, comprising:
obtaining two finger vein images to be compared, wherein the two finger vein images to be compared are single-channel images;
performing image channel fusion on the two finger vein images to be compared to obtain a two-channel target finger vein image to be compared;
inputting the target finger vein image to be compared into a feature extractor, and extracting a feature vector of the target finger vein image to be compared by the feature extractor, wherein the feature extractor is trained by using a two-channel convolutional neural network;
inputting the feature vector of the target finger vein image to be compared into a dichotomy classifier to obtain a dichotomy result; and
determining according to the dichotomy result whether the two finger vein images to be compared come from a same finger.
