چکیده
Biometrics is the word derived from Greek words ―Bio‖ means (life) & ―Metrics‖ means (to measure). Biometrics is the science of measuring human characteristics for the purpose of authenticating or identify ing the identity of an individual. Biometrics System is used for automated recognition of an individual. In Informat ion system in particu lar b iometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance. In this paper, palmprint biometric is used for personal authentication. Various feature extract ion methods to be discussed and compared are Forstner operator, SUSAN operator, Wavelet based salient point detection and Tra jkovic and Hedley corner detector.

Automatic Palmprint Verification
Automic palmprint verification is an important complement of biometric authentication. As the first attempt of personal identification by palmprint, this paper explores different methods for three main processing stages in palmprint verification including datum point registration, line feature extraction and palmprint classification. The datum points of palmprint which have the remarkable advan...
متن کاملPersonal Authentication Using Palmprint with Sobel Code, Canny Edge and Phase Congruency Feature Extraction Method
Palmprint recognition refers to recognizing a person on the basis of palmprint features. In this paper, we have proposed a palmprint based biometric authentication method with improvement in accuracy, so as to make it a real time palmprint authentication system. Several edge detection methods, Directional operator, Wavelet transform, Fourier transform etc. are available to extract line feature ...
متن کاملImage alignment based on invariant features for palmprint identification
Palmprint identification provides a new technique for personal authentication. Previous research on palmprint identification mainly focuses on feature extraction and representation (Pattern Recognition 33(4) (1999) 691). But a crucial issue, palmprint alignment, is not addressed. Palmprint alignment involves moving and rotating the palmprints to locate at their correct position with the same di...

This paper proposed an authentication system based on low quality palmprint. For implementation of this system, first the features is extracted by using Contourlet and wavelet transforms. In the second phase, some of the features are selected by using Across Group Variance (AGV) filter. In the last phase by using a classification method, the authentication is completed. For classification we ev...
