dct based visible watermarking algorithm

This program calculates the temperature profile and seed

仿真程序主体部分由c语言完成,改变运行的设定的参数，在相同的信道编码速率下，通过改变误码率，用Matlab软件进行画图，得出在相同编码速率不同误码率下的纠错后误码的比率，接着改变编码速率，重新可以划出另外的两条曲线；(simulation program from the main part of the completion c language, change the operation of the set parameters, the same channel coding rate, by changing the error rate using Matlab software for drawing, reached the same rate of different coding error rate after correction of the error rate, and then change the coding rate, can be re-drawn the other two curves;)

主要包括图像的中值、均值去噪、非局部均值、分块局部去噪算法；还有均方误差和峰值信噪比评价、以及matlab基础学习资料如边缘检测、小波变化、灰度值转换等(Including image median, mean denoising, non-local means, block local denoising algorithm also mean square error and peak signal to noise ratio evaluation, and matlab based learning materials such as edge detection, wavelet transform, gray scale value conversion wait)

matlab code for mdof linear

用matlab写的以太网报头提取工具。它可以截获网络数据包并记录下它的时间戳、数据包长度和数据域等。(Written by matlab Ethernet header extraction tool. It can be intercepted network packets and record its timestamp, packet length and data domains such as.)

在仿真中，我们规定每个移动节点的发射功率是常数，PTx = 1W；接收节点接收机的灵敏度Smin = -80 dBm；信号质量 min = 2 dB；系统的背景噪声门限INThre = 1.2e-10(In the simulation, we require that each mobile node s transmission power is constant, PTx = 1W receiver node receiver sensitivity Smin =-80 dBm signal quality )

说明：  针对小流域设计洪水计算中，采用推理公式求解洪峰流量Qm及汇流时间τ的方法繁琐，查算精度较低等问题，提出用牛顿迭代法求解，该方法较原图解试算法收敛快，迭代次数少，计算速度快，精度可靠。计算实例表明，用简单迭代法与牛顿迭代法计算设计洪峰流量，其结果与图解试算法完全一致。()

很适合想学习matalab的人，无论初级者还是高级者，这都是一本好书(matalab study)
