Fast Palmprint Authentication by Sobel Code Method

The ideal real time personal authentication system should be fast and accurate to automatically identify a person’s identity. In this paper, we have proposed a palmprint based biometric authentication method with improvement in time and accuracy, so as to make it a real time palmprint authentication system. Several edge detection methods, wavelet transform, phase congruency etc. are available t...

Double-orientation code and nonlinear matching scheme for palmprint recognition

Many palmprint authentication approaches have been proposed in recent years. Among them, the orientation based coding approach, in which the dominant orientation features of palmprints are extracted and encoded into bitwise codes, is one of the most promising approaches. The distance between codes created from two palmprint images is calculated in the matching stage. Reliable orientation featur...

Scatter-difference discriminant locality preserving projections for palmprint recognition

We develop an improved LPP method called scatter-difference discriminant locality preserving projections (SDLPP) for palmprint recognition. SDLPP has better classification capability which benefits from discriminant information obtained by maximizing the difference of between-class separability and within-class similarity. SDLPP avoids the singularity problem for the high-dimensional data matri...

Gaussianization of image patches for efficient palmprint recognition

In this paper we present a comparison of the two dominant image preprocessing techniques for palmprint recognition, namely, histogram equalization and mean-variance normalization. We show that both techniques pursue a similar goal and that the difference in recognition efficiency stems from the fact that not all assumptions underlying the mean-variance normalization approach are always met. We ...
