拉普拉斯二维主成分分析及其在人脸识别中的应用
Laplacian’s Two-dimensional Principal Component Analysis and Its Application to Face Recognition
【摘要】 在二维主成分分析的基础上,考虑样本的流形分布特点,引入样本相似系数,重新定义了样本拉普拉斯散布矩阵,进而给出了基于拉普拉斯二维主成分分析的特征提取方法.在ORL,FERET人脸库上的试验证明了基于拉普拉斯二维主成分分析方法的有效性.
【Abstract】 Based on two-dimensional principal component analysis,this paper investigates the features of manifold distribution.Sample similarity coefficient is introduced to redefine Laplacian scattering matrix,and thus a feature extraction method of this kind is worked out.The results of the experiments conducted on ORL and FERET face database indicate that the method is effective.
