改进ICA的人脸特征提取方法

Face Feature Extraction Method Based on ICA

在人脸特征提取的过程中主要采用ICA方法。介绍了ICA算法的原理,并对ICA算法的优缺点进行了讨论,给出了改进的ICA算法。试验结果表明,改进的ICA算法应用于人脸的特征提取比PCA算法更具有优越性,所提取的人脸特征更利于人脸的分类,从而获得较高的识别率。

This paper presents a method to extract face feature by using ICA.Firstly,it introduces independent component analysis(ICA) algorithm.Then,discusses the advantage and disadvantage of this method and gives a new algorithm on ICA.The results indicate that ICA using in t recognition and face feature extraction is better than PCA.
