Abstract

The invention discloses a finger vein recognition unlocking method and system. According to the method, binaryzation is carried out on a finger vein image in an image preprocessing stage; a region ofinterest is denoised and extracted; operations such as enhancement and normalization are performed; a region of interest is accurately extracted; de-noising is carried out again after image segmentation; cavities are filled. image post-processing such as burr filtering and skeletonization is carried out; According to the method, the finger vein to-be-identified sample with clear and effective finger vein characteristics can be quickly and efficiently extracted, the finger vein to-be-identified sample is quickly matched with the finger vein identification template stored in the database, if thematching is successful, the unlocking signal is output for unlocking, and the finger vein identification and unlocking efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of finger vein unlocking, in particular to a finger vein recognition unlocking method and system. Background technique [0002] In today's informatization, information security has been widely concerned by the society, and people have put forward newer and higher requirements for information security. Using the inherent characteristics of the human body such as fingerprints, veins, voice, iris, face and other biometric identity authentication gradually replaces traditional unlocking methods such as keys, IC cards, and passwords with its outstanding advantages. [0003] In recent years, more unlocking methods have begun to unlock through biometric features. For example, patent 201810564041.1 discloses a face recognition system, which processes face images through an information processing module, and improves the processing speed of access control through the division and cooperation of multiple acce...
