摘要: 提出了一种新的人脸识别算法。该算法采用Gabor小波和一种新颖的方式来提取人脸特征,利用局部线性嵌入(Locally Linear Embedding,LLE)算法来实现数据的非线性降维处理,最后训练基于欧式距离的最近邻分类器进行分类判决。在ORL人脸库中与PCA方法、Gabor小波+PCA方法和直接的LLE算法进行了实验比较,实验结果表明,提出的Gabor小波+LLE的方法具有更优的性能。

Abstract: A novel algorithm for face recognition is presented. The algorithm used Gabor wavelet transform and a new method for face feature extraction,calculates Locally Linear Embedding(LLE) for nonlinear dimensionality reduction of face data,and trained a nearest neighbor classifier for classification. The comparison among the proposed approach,PCA method,Gabor+PCA method and direct LLE method is carried out on ORL face database. The experimental results show that the proposed algorithm is superior to other methods.
