PALM VEIN RECOGNITION SYSTEM Russian patent published in 2025 - IPC G06V40/14 G06V10/774 

FIELD: data processing.

SUBSTANCE: invention relates to biometrics, in particular to identification of a person by an image of his/her hand. Palm vein pattern recognition system comprises: a palm image reader in communication with a remote processing device. Palm image reading device comprises: a means of illuminating the palm with infrared radiation; palm imaging means; correction means, means of transmitting image data to a remote processing device. Remote processing device comprises a palm recognition facility, an identification facility and an access facility. Palm recognition means is configured to simulate an image of a palm with a modified vein pattern at low temperatures for training the neural network and recognizing the palm vein pattern by the trained neural network at low temperatures; training algorithm is based on a neural network which implements the function of displaying a pattern of veins of palms from a plurality of images into a plurality of biometric templates.

EFFECT: high accuracy and speed of identifying a person from an image of his/her hand at low temperatures.
