Research And Realization Of Palmprint Identification System

Biometrics, which refers to the identification of a person by certain biological features such as fingerprint, iris, face and palmprint or behavioral features. It can be used to reinforce or even replace the traditional identification tools. It is becoming a potential technology in this era.Palmprint identification is a new branch of biometric technology. Since palmprint has the uniqueness and stability as fingerprint, the personal authentication can be determined completely by the line, geometry and texture features. The identification system based on palmprint techonoly is friendly and easy to capture image, which can be applied to homeland security, social welfare, financial and ecommerce. Palmprint identification technology will become a new research and application field for personal authentication. it's also the important supplement of the identification technology based on the fingerprint.This dissertation firstly concentrates on the research of the key technologies and algorithms of the palmprint identification system, and then tries to construct a palmprint identification system applied to social welfare. The main contents are as follows:1. Introduction of biometrics and palmprint.2. The procedure of a palmprint identification system.3. Palmprint acquisition using DirectShow technology.4. Palmprint location. A new location method based on corner detection is presented to get the palmprint feature.5. Feature extraction and feature representation. A new feature extraction method is presented to reduce the algorithm complexity.6. On-line palmprint registration and identification. Database developed with ADO interface.
