这是一个用极大似然函数估计狄里克莱分布的matlab程序(This is a great likelihood function using the estimated Dirichlet distribution matlab program)

基于DWT和DCT的图象水印算法,过程简单,效果一般(DWT and DCT-based image watermarking algorithm, the process is simple, the effect of general)

Spectrum and cepstrum analysis

IT++ is a C++ library of mathematical, signal processing and communication routines.

一个线性预测的matlab仿真程序，先用模型生成原始信号(平稳随机过程)，然后利用最小均方误差准则计算出预测系数，最后利用预测系数对原始信号进行预测(利用原始信号过去n个时刻的值预测当前时刻的值)。(This is a matlab program for linear prediction. First, we use all-pole model to generate a signal(stationary signal), then utilize the Minimum Mean-Square Error to compute the filter cofficient, at last we can use the filter cofficient to predict(use past n signal data to predict current signal data).)

power flow analysis

对图像进行任意角度旋转 图像渐变 运用调色板设计技术将灰度图像彩色化 等5个MATLAB 图像处理 代码(Rotate the image at any angle image gradient design using the gray image palette color and so on five MATLAB image processing code)

说明：  一本matlab的虚拟现实的讲义，书写的还不错！(A virtual reality matlab lecture notes, writing bad!)

说明：  可以通过截取文献中的图片进而提取文献曲线中的数据(capture the data of curves in ref.)

实现双三次插值图像缩放算法，修改k值，即可修改放大倍数或缩小倍数！(To achieve bi-cubic interpolation algorithm for image scaling, modified k values can be modified to enlarge or shrink the multiples of multiples!)
