Abstract:

The palmprint recognition is a new biometric technology, which has a good prospect of applications in the areas of network security, identity authentication etc. In this paper, the principal component analysis method is applied to palmprint image feature extraction, and the differences between the traditional principal component analysis(PCA) and the weighted principal component analysis(WPCA) in addressing the palmprint image are explained.
