The results indicate that the extracted face features are valid and the design of classifier is sound and efficient 实验结果表明,本文所提取的人脸特征是有效的,分类器的设计也是合理而高效的。
Face detection is an arduous work mainly because extracting face features in face pattern is very difficult 人脸检测是一项艰巨的工作,主要原因是人脸特征在人脸模式中的提取是一项非常艰巨的工作。
Finally, the experiment results of face recognition are presented and analyzed . the results indicate that the extracted face features are valid and this system is more exact and efficient 实验结果表明,本文所提出的人脸检测算法是可行的,提取的人脸特征是合理有效的,系统识别正确率较高,速度快。
In the process of extracting face features for recognition, pure pca method can obtain the best features in the sense of representation, but these features are not very suitable for classification purposes 单纯采用pca方法来进行人脸特征的提取,得到的是人脸的最佳表示特征,但这些特征对于分类来说并不是最佳的。
The so-called face recognition is the face classification by firstly using certain algorithm to extract face features and then matching face features, which includes face tracking, face detecting, face feature detecting, face recognition, emotion analysis, an so on 通过某种算法提取人脸的面部特征,然后进行特征匹配以确定人脸的归属,这就是所谓的人脸识别。它包括人脸跟踪、人脸检测、面部特征点检测、人脸识别、表情分析等多种内容。
