pca人脸识别 基于代数统计的方法是使用统计学观点提取基向量，之后将人脸向量投影到基向量上，得到的投影值即为不同的人脸图像特征，这种方法利于操作，比较灵活。本次设计采用PCA方法对人脸进行降维，提取特征。

-pca face recognition based on the statistical method Generation is extracted base vectors using a statistical point of view, and then the vector of the face is projected to a base vector the projection value obtained is the type of face image feature, this method is beneficial operation more flexible . The design uses PCA dimensionality reduction, human face feature extraction.
