Palmprint Authentication System Using Wavelet based Pseudo Zernike Moments Features

چکیده
In this paper, a novel method of image based palmprint matching based on features extracted from wavelet-based pseudo Zernike moments feature descriptor is proposed. Pseudo Zernike moments have additional properties of being more robust to image noise, possessing geometrical invariants property, having a nearly zero value of redundancy measure in a moment set due to its orthogonality property and having a superior image representative capability; while wavelet analysis affords major advantages of performing local analysis (describe image local characteristic) due to its excellent localization property and decomposing image to ease image information interpretation. Therefore, the hybrid wavelet transform and pseudo Zernike moments is able to comprise salient features from both imaging apparatus and achieve better verification rate. Comparison analysis shows that the hybrid wavelet transform and pseudo Zernike moments is able to achieve superior performance than the other wellknown moments.

Palmprint Verification with Moments
Palmprint verification is an approach for verifying a palmprint input by matching the input to the claimed identity template stored in a database. If the dissimilarity measure between the input and the claimed template is below the predefined threshold value, the palmprint input is verified possessing same identity as the claimed identity template. This paper introduces an experimental evaluati...

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...
