Abstract

The invention provides a palmar vein extraction method and a palmar vein extraction device. The method comprises the steps of collecting a palmar vein image; pre-processing the palmar vein image to obtain an area-of-interest; and extracting palmar vein characteristics based on the area-of-interest. Therefore, clean and accurate palmar vein characteristic image information can be extracted so as to reduce adverse effect on identification of the palmar vein characteristics, decrease interference factors and improve the identification rate.

Description

technical field [0001] The invention relates to the field of biological information identification, in particular to a method and device for extracting palm veins. Background technique [0002] With the globalization of the economic circle and the acceleration of informatization, people have begun to put forward higher security requirements for the social environment they depend on for survival, and people need safer and more convenient identity authentication technology. Due to the characteristics of stability, uniqueness and convenience of biometric technology, biometric technology is used as a means of identity verification to gradually replace traditional identification methods such as keys and passwords. Biological features can be roughly divided into external features (such as fingerprints, palm prints, faces, auricles, etc.), and internal features (such as palm veins, dorsal veins, irises, etc.). Compared with external features such as fingerprints, palm veins, which...
