kmeans

说明：  基于非负矩阵分解（NMF）的人脸特征提取算法，NMF基本思想是找到一个线性子空间W，使的构成子空间的基本图像的像素点都是正值，而且人脸图像在子空间上的投影系数也是正数(Non-negative Matrix Factorization (NMF) of facial feature extraction algorithm, NMF basic idea is to find a linear sub-space W, so that the composition of sub-space of the basic image pixels are positive, and face image in the sub-space projection coefficient is positive)

4个非常简单的matlab滤波程序，线性滤波、中值滤波、二维自适应滤波、top-hat滤波(4 very simple matlab filtering program, linear filtering, median filtering, the two-dimensional adaptive filtering, top-hat filter)

程序的主要目的是获得光学传递函数，通过光程差获得光瞳函数，之后获得点扩散函数，最终得到光学传递函数。(The main purpose of the program is to obtain an optical transfer function, the pupil function obtained by the optical path difference, after obtaining the point spread function, the finally obtained optical transfer function.)
