face recognition using PCA buy opencv

人臉辨識，訓練+測試 且運用PCA 降低為度找出特徵向量-Face recognition, training+ tested and find out the degree of reduction using PCA eigenvectors

用OPENCV实现了人脸识别系统，采用ORL人脸库进行测试，选择每个身份前5张做训练图，一共200个训练样本。-OPENCV achieved using face recognition system that uses the ORL testing, each identity before choosing to do training Figure 5, a total of 200 training samples.
