Face recognition based on sub-pattern two-directional two-dimensional linear discriminant analysis
摘要
Abstract
To reduce the impacts of the variations of expression and illumination,a novel face recogni-tion method based on sub-pattern two-directional two-dimensional linear discriminant analysis (Sp-(2D)2 LDA)is presented in this paper.Firstly,Sp-(2D)2 LDA divides the original images into smaller sub-images and keeps the spatial relationship between the sub-images.Secondly,it simultaneously ap-plies 2DLDA to the subsets of the training samples in the row and column directions to extract local sub-features.Finally,the sub-features are synthesized into global features and nearest neighbor clas-sifier is used for classification.The experimental results on Yale and ORL face databases show that the proposed Sp-(2D)2 LDA method effectively reduce not only the dimension of the eigenvectors,but also the influence of variations in illumination and facial expression.Thus,the proposed method has better classification performances than the other related methods.关键词
