DCT based Image Watermarking matlab code

这是利用matlab编写的求湖水面积的例程，用到了蒙特卡洛方法，希望有所帮助。(It is written using matlab routine seek the lake area, use the Monte Carlo method, hope help.)

此文件包含有四个基于matlab源程序,可直接运行.其说明如下 P0305：模拟图像受高斯白噪声和椒盐噪声的影响 P0306：采用二维中值滤波函数medfilt2对受椒盐噪声干扰的图像滤P0307：采用MATLAB中的函数filter2对受噪声干扰的图像进行均值P0308：图像的自适应魏纳滤波 (This file contains four based on the matlab source code can be directly run. Its description is as follows P0305: analog image by Gaussian white noise and salt and pepper noise P0306: A two-dimensional median filtering function medfilt2 by salt and pepper noise to the image filter P0307: the use of MATLAB in filter2 function affected by noise interference images mean P0308: Image Adaptive Weiner Filter)

说明：  MATLAB是矩阵实验室（Matrix Laboratory）的简称，是美国MathWorks公司出品的商业数学软件，用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境，主要包括MATLAB和Simulink两大部分(MATLAB is Matrix lab (Matrix Laboratory) abbreviation, is the product of our company MathWorks business mathematics software for algorithm development, data visualization, data analysis and numerical calculation of the senior technical calculation language and interactive environment, mainly including MATLAB and Simulink two most )

基于matlab的dmc算法改进，m文件编写，计算更加简略，有助于新手学习。(Based on the improved algorithm matlab dmc, m document preparation.)

实现了统一潮流控制器的建模与设计，可以稳定运行(Modeling and design of unified power flow controller)

利用matlab里面的吹风机数据，用前300个数据进行辨识。分别采用最小二乘辨识和相关性系数法辨识。并画出图形。通过对比最小二乘法和相关函数两种方法得出来的辨识图形。可知相关函数辨识的准确度更高。(Use a hair dryer inside matlab data before using 300 data identification. Were used to identify the least squares identification and correlation coefficient method. And draw graphics. By comparing the least squares method and related functions have two ways out of the identification graphics. Shows a higher correlation function identification accuracy.)

基于LMS算法的自适应回波抵消系统。 可应用与无线直放站回波抵消算法，改善25DB。 也应用与噪声抵消系统。(base on lms arithmetic A Radio Repeater Interference Cancellation Model for MobileCommunication Systems )

说明：  EM算法的Matlab实现，针对GMM模型(EM algorithm for GMM Model)
