| 摘 要： | 提出一种改进的基于Gabor小波变换和二维主分量分析2DPCA(2-Dimensional Principal component analysis)的掌纹识别。2DPCA克服了传统Gabor小波变换后直接进行主分量分析PCA(Principal component analysis)遇到的维数灾难问题,并且将PCA与Fisher线性判别FLD(Fisher Linear Discriminate)结合起来,利用了以前仅用于降维的PCA特征和FLD特征相融合进行掌纹识别。基于PolyU掌纹库的实验结果表明,该方法不仅有更高的识别率,而且维数更低。

| Abstract: | This paper presents an improved palmprint recognition method using Gabor wavelets transform and 2-dimentional principal component analysis(2DPCA).2DPCA in this method overcomes the curse of dimensionality encountered in traditional way of making principal component analysis(PCA) directly after Gabor wavelets transform,moreover,PCA is integrated with Fisher linear discrimination(FLD),and the PCA features,of which only being used to reduce dimensions in the past,and the FLD feature are fused to carry out palm... |
