在这篇文章中，我们主要阐述了基于PCA和LDA的人脸识别技术。这个技术包含两个步骤：首先，我们通过PCA将人脸图片从原始向量空间中提取到子向量空间——特征脸空间；然后，再通过LDA获得一个线性分类器。
In this article, we mainly elaborated based on PCA and LDA face recognition technology. This technique consists of two steps: First, we will face images extracted from the original vector space to sub-vector space by PCA- Eigenface space Then, LDA obtained by a linear classifier.

模式识别是以应用为基础，目的是将图像进行分类。这些对象与应用领域有关，可以是图像、波形或者任何可测量且需要分类的对象。虹膜识别即为模式识别的一个主要应用，一个自动虹膜识别系统包含硬件和软件两大模块，虹膜图像获取装置和虹膜识别算法，分别对应于图像获取和模式匹配这两个基本问题。
Pattern recognition is based on the application purpose is to image classification. Related to the field with the application of these objects can be images, waveforms or any classification of the object and need to be measured. Iris recognition is the one of the main application of pattern recognition, an automatic iris recognition system consists of two modules of hardware and software, iris image acquisition devices, and iris recognition algorithms, corresponding to image acquisition and pattern matching of these two basic questions.
