用matlab求二维凸包，并求出二维凸包的面积(Using matlab to calculate the two-dimensional convex hull, and find the two-dimensional convex hull area)

一种生成平衡的gold序列，并且还绘制了gold序列的自相关函数和互相关函数的波形图！！(Generation balance of gold)

<模式识别与智能计算——matlab技术实现>书的配套程序(" Pattern Recognition and Intelligent Computing- matlab technology" book matching program)

功率谱估计（周期图法、welch法、pmusic法等）(PSD estimation)

代码是根据文献思想自己编写，已经过多次试验，实现对图像处理过程中的svd分解，过程中需要调用一个omp函数，可以自己随便调用一个(The code literature thinking of their own writing, has been repeatedly test svd decomposition of image processing, the process need to call a omp function can casually call a)

灰色系统模型预报钟差.给出了实际例子，并附实例图像。(Gray model clock error forecast )

这是matlab版的视频水印，仅供初学者参考。(This is videowatermark code.)

利用DCT域进行扩频水印的嵌入,含实验图像，和各种经典的攻击方式。可选择嵌入强度和攻击强度。利用Matlab编写(DCT domain using spread-spectrum watermark embedding, with the experimental images, and various classical attacks. The option embedded in the strength and intensity of attacks. Prepared using Matlab)
