| 摘 要： | 人脸自动识别方法已成为当前模式识别和人工智能领域的一个研究热点,人脸特征提取是人脸识别技术的关键。首先介绍了人脸图像的预处理过程,PCA和ICA算法的原理,针对PCA和ICA算法本身优缺点,提出一种新的基于PCA/ICA的人脸特征提取方法,最后采用最近邻分类器,对ORL人脸库进行分类识别。实验证明,改进的方法优于PCA算法和ICA算法。

| Abstract: | Face recognition is attractive in pattern recognition and artifical intelligence field,face feature extraction is important in face recognition.This paper first introduced preprocessing of face images,PCA and ICA algorithm.Considering PCA and ICA algorithm each have its advantages and disadvantages,then proposes a novel face feature extraction method based on PCA/ICA.The NN classifier,is select to face classification and recognition on the ORL face database.Experiments indicated that the modified method is supe rior to PCA algorithm and ICA algorithm. |
