指纹识别是模式识别中的一个十分重要课题。结合小波变换(WT)、二维主元分析(2DPCA)和椭球基函数(EBF)特点,本文提出了一种基于WT和2DPCA的EBF神经网络指纹识别方法。首先,利用小波变换将原始图像分解为高频分量和低频分量,并忽略水平高频与垂直高频分量,获得原始图像的基本特征。然后,通过2DPCA算法对该图像进行降维,获取降维特征;最后结合椭球基函数神经网络(Ellipsoidal Basis Function Neural Network, EBFNN)完成指纹识别。本算法将2DPCA优化的特征提取与EBFNN的自适应性相结合,在FVC2000(国际指纹竞赛数据库)上作了测试。并与WT-PNN算法和WT-2DPCA-RBF算法进行比较。实验结果表明,本文提出的算法在平移、旋转及光照变化的指纹数据库上的识别效果优于WT-PNN算法和WT-2DPCA-RBF算法。
Abstract
Fingerprint recognition is a very important question in pattern recognition. Combined with wavelet transform (WT), two-dimensional principal component analysis(2DPCA) and Ellipsoidal Basis Function (EBF)
a novel fingerprint recognition algorithm has been proposed in this paper
which is based on wavelet transform
two-dimensional principal component analysis and EBF neural network. Firstly
original images are decomposed into high-frequency and low-frequency components with the help of WT
and high-frequency components are ignored
so the prime features of original images can be attained.Secondly
the projected features are solved by 2DPCA.Finally,fingerprint recognition can be realized by Ellipsoidal Basis Function Neural Network(EBFNN). The algorithm combines the optimization of the 2DPCA and the adaptability of EBFNN. The experimental results based on FVC2000 have verified that the proposed algorithm has higher recognition rate than WT-PNN and WT-2DPCA-RBF.
