先用PCA降维，然后使用OMP识别人脸图像。人脸库是ORL人脸库。-First with PCA dimensionality reduction, and then use the OMP face image recognition. Face is the ORL.

人脸表情识别，稀疏表示，人脸表情图片，表情库。matlab程序实现，绝对可以调试运行。 毕业设计内容。-Facial expression recognition, sparse representation, facial expression, facial expression . Matlab programming, can debug the operation. Graduation design content.

ICA和PCA两种方法，实现了基于ORL人脸库的方法。识别率较高，适合初学者学习。-ICA and PCA are two ways to achieve based on ORL face approach. High recognition rate, suitable for beginners to learn.

IOS平台下，利用Opencv开源库实现了人脸的识别，国外博客上搜到的。-The IOS platform, the use of Opencv open-source library implementation of the human face recognition, foreign blog search.
