Abstract

The invention provides a hand vein recognition method based on the fusion of structure coding characteristics and texture coding characteristics, belonging to the technical field of intelligent monitoring in computer vision. The method comprises the following steps of: step 1, acquiring and preprocessing an image; step 2, extracting the structure coding characteristics; step 3, extracting the hand vein texture coding characteristics; step 4, fusing the structure coding characteristics with the hand vein texture coding characteristics; and step 5, performing recognition through a sorter, thereby obtaining a result. The invention provides the hand vein recognition method based on the fusion of the structure coding characteristics and the texture coding characteristics, wherein binary codingis performed on the extracted structure characteristics and texture characteristics, which is advantageous for the retention of information in the characteristic fusion; the result obtained by fusingthe characteristics is far better than the result of recognition obtained by only employing the structure coding characteristics and the result of recognition obtained by only employing the texture coding characteristics; and the robustness for image distortion and wrong segmentation is high, therefore, the hand vein can be correctly recognized in the presence of certain image distortion and wrong segmentation.

Description

technical field

[0001] The invention relates to a hand vein recognition method based on the fusion of structural coding features and texture coding features, which belongs to the technical field of intelligent monitoring in computer vision, and in particular relates to the technical field of biological feature recognition. Background technique

[0002] Biometric identification is an important technology for identification based on computer systems. Compared with traditional authentication methods such as passwords and magnetic cards, it has the advantages of not being forgotten, not easy to forge or be stolen, "carrying" with you and being available anytime and anywhere. It is more secure, confidential and convenient. Wide range of applications such as. The current common biometric identification methods are face, fingerprint, hand shape, foot shape, ear shape, teeth, iris, voice, handwriting, gait, etc. Among them, face and fingerprint have been developed for many years, ...
