图像数字水印的方案毕业论文

分类列出了matlab中主要的函数和命令列表,方便查询(A breakdown of the matlab main function and the command list to facilitate query)

说明：  MathCAD是美国Mathsoft公司推出的一个交互式的数学软件。该软件定位于向广大教师、学生、工程人员提供一个兼备文字处理、数学和图形能力的集成工作环境，使他们能方便地准备教案、完成作业和准备科学分析报告。在输入一个数学公式、方程组、矩阵之后，计算机能直接给出结果，而无须去考虑中间计算过程。在加入软件包自带的Maple插件后能直接支持符号运算。你可以在计算机上输入数学公式、符号和等式等，很容易地算出代数、积分、三角以及很多科技领域中的复杂表达式的值，并可显示数学表格和图形,通过对图形结果的分析，使我们对问题的理解更加形象。 在实际应用中，MathCAD好比是一个功能强大的计算器，它没有很复杂的规则；同时它也可以和Word等字处理软件很好地配合使用，所以也可以把它当作一个出色的全屏幕数学公式编辑器来使用。 Mathcad的用户主要针对具备应用数学知识但并不要求具有较多的计算机知识的用户，如工程研究人员、学生等。 (MathCAD is a Mathsoft Launches interactive mathematical software. The software is targeted to the vast numbers of teachers, students, engineers to provide a mix of word-processing, mathematics and graphics capabilities of the integrated working environment, so that they can make it easier to prepare lesson plans, homework and prepare for scientific analysis. In the importation of a mathematical formula, equations, matrices, the computer can directly give the result without the need to consider the middle of the calculation process. Before joining the Maple software package comes with plug-ins can directly support the operation symbol. You can enter a computer mathematical formula, such as symbols and equations, it is easy to calculate the algebra, Integral, Triangle, and many of the complex field of science and technology in the value of expression, and mathematical tables and graphics show through an analysis of the results of graphics so that our understanding of the issues more imag)

说明：  将信号转换至FRFT域的函数，算是比较好用的一个集合吧(Converting signals to functions in FRFT domain is a better set.)

Function to do PCA on an RGB image

AP聚类方法，是08年发表在“科学”上的聚类方法，本人从图像图像方面研究近十年，这是我所见过最好的聚类算法，本程序提供聚类演示，还把它用图像分割试验（matlab7.0环境调试）。(AP clustering method, is 08 published in " Science" on the clustering method, the image from the image in my research in recent years, this is the best I have ever seen clustering algorithm, Clustering presentation of this program provides, but also test it with the image segmentation (matlab7.0 debugging environment).)

将图像分为16*16的分块进行计算,稀疏矩阵采用DCT矩阵，观测矩阵采用高斯随机矩阵，重构采用OMP算法,对256*256大小的8bit灰度lena图像进行仿真( )

该程序是基于matlab平台而编成的，解决分布拟合度卡方检验算法(The program is based on and derived from matlab platform to address the distribution of fit chi-square test algorithm)

粒子群算法参数辨识，用于调速系统参数辨识的适应度函数选择(Particle swarm optimization)

这个例子展示了用MATLAB(IQ)创建一个复杂的基带信号,下载这个信号到矢量信号发生器、射频载波信号的上转换,和射频信号的生成。下载的信号和控制仪器使用仪器控制工具箱™ ,它支持通过接口沟通工具和驱动。(This example shows the creation of a complex baseband (IQ) signal with MATLAB® , the download of this signal to a vector signal generator, the upconversion of the signal to an RF carrier, and the generation of the RF signal the instrument. The download of the signal and control of the instrument uses Instrument Control Toolbox™ , which supports communication with instruments through interfaces and drivers.)
