文中分别用主成分分析、独立成分分析以及线性鉴别分析方法对图像进行特征抽取,同时采用K近邻算法和支持向量机算法进行人脸图像分类.通过在YALE人脸图像库上实验,结果表明:多种特征抽取方法下的图像分类算法是有效的.
A comprehensive performance comparison of face image extraction among three different feature extraction methods including principal component analysis,linear discriminant analysis,and independent component analysis.is made respectively.Moreover,the face image classification is also performed by using the K Nearest Neighbor(KNN) and Support Vector Machine(SVM) algorithms.Experimental results conducted on the YALE face image database demonstrate the effectiveness of the proposed method based on the different feature spaces.
