| 摘 要： | 提出了一种基于特征融合的人脸识别方法.该方法首先对预处理后的人脸图像进行全局特征及局部分量的提取,分别采用离散余弦交换(DCT)提取包含图像大量信息的低频部分特征和奇异值分解(SVD)抽取图像的代数特征作为图像的全局特征,采用非负矩阵分解(NMF)提取图像的局部分量特征,然后将此两类特征以独立成份分析(ICA)进行融合,获取用于人脸识别的特征向量.在本文的实验中,我们将此特征向量应用于支持向量机(SVM)进行分类训练及识别测试,并获得较好的结果.

| Abstract: | We proposod a novel algorithm for facial recognition based on features fusion in support vector machine (SVM). First, some local features and global features from pre-processed face images were obtained. The global features were obtained by making use of discrete cosine transform (DCT) and singular value decomposition (SVD). At the same time, the local features by utilizing non-negative matrix factorization (NMF) were also obtained. Furthermore, the feature vectors fused by independent component analysis (ICA)with global and local features were given. Finally, the feature vectors were used to train SVM to realize the face recognition, and the computer simulation illustrated the effectivity of this method on the ORL face database. |
