Finger vein comparison method, computer equipment, and storage medium

Computer equipment, comprising:

• a memory, a processor, and a computer readable instruction stored in the memory and capable of running on the processor, wherein the processor, when executing the computer readable instruction, implements:
• obtaining two finger vein images to be compared, wherein the two finger vein images 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.

A non-transitory computer readable storage medium that stores a computer readable instruction, wherein the computer readable instruction, when executed by a processor, enables the processor to implement:

• obtaining two finger vein images to be compared are obtained, wherein the two finger vein images 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.
