Embodiment Construction

[0029] The basic flow of the solution in this embodiment is as follows figure 1 shown, including the following steps:

[0030] S1. Generate a positioning pattern with screening properties suitable for drawing on the palm of a person, and draw the pattern on the palm; screening properties, in this embodiment, refer to: the pattern itself has two parts, black and transparent, and the black part is covered ; the transparent part, revealing the texture of the skin. That is: the skin can be selectively covered and revealed.

[0031] S2, taking a palm image with a positioning pattern;

[0032] S3. According to the positioning pattern positioning, extract a region of interest (ROI, Region of Interest) from one or more regions selected in the pattern design;

[0033] S4. Extract features from the located one or more regions of interest;

[0034] S5. Use the extracted features to perform texture recognition, including palmprint recognition and positioning pattern recognition.

Abstract

The invention provides a palm print recognition method and system, and the method comprises the following steps: S1, generating a positioning pattern which is suitable for being drawn on the palm of aperson and has a screening property, so as to draw the pattern on the palm; S2, shooting a palm image with a positioning pattern; S3, positioning according to the positioning pattern, and extractingan interested region from one or more regions selected from the pattern design; S4, extracting features from the positioned one or more regions of interest; and S5, carrying out texture recognition byutilizing the extracted features, and carrying out positioning pattern recognition on the positioning pattern with other recognizable information. Biometric feature recognition after transfer printing of patterns such as two-dimensional codes is recognition combining transfer printing patterns and skin textures. Thus, the revocable and reusable recognition features are guaranteed through the transfer printing pattern, and the skin texture ensures the reliability of identity recognition of people.

Description

technical field [0001] The invention belongs to the field of biometric identification, and in particular relates to a palmprint identification method and system. [0002] technical background [0003] Biometric identification technology extracts the features of the human body surface to identify the identity. Compared with methods such as keys and passwords that identify identities with information about possessions and memories, biometrics will not be lost or forgotten, which is more secure and convenient. Biometric recognition technology has achieved extensive development under the recent opportunity of the explosion of information technology and artificial intelligence. [0004] Common biometric identification methods include fingerprint identification, face identification, iris identification, and palmprint identification. But one characteristic of these identification technologies is that their biometrics remain unchanged for life, or at least remain stable over a long...
