用MATLAB合成歌唱祖国，包括初步与简单改变（包络）(Ode to the Motherland synthesis using MATLAB, including the initial and simple to change (the envelope))

K-means clustering algorithm

利用MATLAB中的GUI（图形用户界面），实现图像的频率位移变换、加入高斯噪声、图像平滑、离散余弦变换、图像反转，并设计了退出按钮(In MATLAB GUI (graphical user interface), to achieve the image displacement transducer frequency, adding Gaussian noise, image smoothing, discrete cosine transform, image reversal, and designed the Exit button.)

说明：  这个程序是用MATLAB编写得一个灰度共生矩阵特征及其一些参数得计算，希望对大家有用。(The MATLAB program is written, a GLCM features and some of the parameters was calculated, and I hope useful.)
