基于奇异值分解的人脸识别方法
梁毅雄 龚卫国 潘英俊 李伟红 刘嘉敏 张红梅
提出了一种将傅里叶变换和奇异值分解相结合的人脸自动识别方法.首先对人脸图像进行傅里叶变换,得到其具有位移不变特性的振幅谱表征.其次,从所有训练图像样本的振幅谱表征中给定标准脸并对其进行奇异值分解,求出标准特征矩阵,再将人脸的振幅谱表征投影到标准特征矩阵后得到的投影系数作为该人脸的模式特征.然后,对经典的最近邻分类器算法进行了改进,并采用模式特征之间的欧式距离作为相似性度量,从而完成对未知人脸的识别.采用ORL

脑神经网络信号的离散余弦分类。所谓分类就是一种模式识别。按照某个特定标准(如距离准则)把一个数据集分割成不同的类或簇,分类后同一类的数据尽可能聚集到一起,不同数据尽量分离。而离散余弦变换是一种用来数据压缩的正交变换。所谓数据的压缩实际上就是通过丢失能量较小高频分量,保留能量较高的低频分量,从而达到压缩的目的。-Brain network signal discrete cosine classification. The so-called classification is a kind of
