:数字水印技术在数字产品的版权保护中起着非常重要的作用。概括了数字水印技术的现状及其基本原理,并 分析了变换域数字水印算法的优势,详细阐述了DCT 水印嵌入和提取算法的原理和步骤。最后在Matlab 平台下对DCT 数 字水印算法进行了仿真,仿真结果证实了DCT 算法的强健性和鲁棒性。(: digital watermarking technology in the digital copyright protection products played a very important role. Summarized the digital watermarking technology and the status of the basic principles and transform domain analysis of digital watermarking algorithm advantages, elaborate on the DCT watermark embedding and extraction algorithm theory and steps. Finally in Matlab platform for DCT digital watermarking algorithm for the simulation, Simulation results confirmed the DCT are strong and robust.)

A simple nonlinear system is described within the Simulink environment.For control purposes, a sliding mode controller is designed in order to regulate the system to the origin. Furthermore, the chattering reduction has also been addressed with the introduction of tanh function.

对于一个随机的非高斯信号或者一个确定信号有很多的信息（远不止功率谱...）。本工具用来分析高阶谱和时频分布。(For a random signal or a set of non-Gaussian signals have a lot of information (far more than the power spectrum ...)。 This tool is used to analyze higher-order spectra and time-frequency distribution.)

说明：  一种MGA方法(Contourlet变换)程序包，相信对从事基于图像表示理论方面的朋友一定有用！(A kind of MGA method (Contourlet transform) package, I believe in the theory of image-based friends that must be useful!)
