Matthew J.Beal的变分贝叶斯理论在隐马尔可夫模型中的应用程序。多加了个转换程序。(VBEM of Matthew J.Beal to HMM.)

本演示实现了主动轮廓模型由Kass等人提出。 要运行它的图形用户界面 1。基于MATLAB型引导提示。 2。关于“到现有的图形用户界面，点击” 3。选择在与本文件相同的目录snk.fig文件 4。按一下上方的绿色箭头启动图形界面 一旦GUI已经启动，您可以通过使用蛇 1。点击“新形象”，并加载输入图像。提供的样品图像。 2。平滑参数设置“西格玛”或保留其默认值并点击“过滤器”。这将平滑图像。 3。只要你点击“过滤器”，头发会出现交叉，用他们和你左击鼠标，您可以选择在图像上的初始轮廓的位置。会出现一个红色圆圈到处您单击并在多数情况下，你应该单击对象周围的一切你想要的部分。最后一点，必须挑选使用右键单击，以阻止更多的积分为MATLAB的要求。 4。设置各种蛇参数（在能源方面的相对权重的蛇目标函数）或离开它们的默认值，然后按一下他们“迭代”按钮。蛇会出现和移动，因为它收敛到它的低能量状态。(This demo implements the Active Contour Models as proposed by Kass et al. To run it with GUI 1. Type guide on the matlab prompt. 2. Click on "Go to Existing GUI" 3. Select the snk.fig file in the same directory as this file 4. Click the green arrow at the top to launch the GUI Once the GUI has been launched, you can use snakes by 1. Click on "New Image" and load an input image. Samples image are provided. 2. Set the smoothing parameter "sigma" or leave it at its default value and click "Filter". This will smooth the image. 3. As soon as you click "Filter", cross hairs would appear and using them and left click of you mouse you can pick initial contour location on the image. A red circle would appear everywhere you click and in most cases you should click all the way around the object you want to segment. The last point must be picked using a right-click in order to stop matlab for asking for more points. 4. Set the various snake paramete)

基于非局部均值图像去噪，对高斯加噪声有很好的去除效果，其中的修改程序，加入了对称处理，处理对称图像效果更好(Based on non-local means image denoising, the high Alaska noise removal, which modify the program, joined the symmetrical treatment, processing symmetrical image effect better)

应用MATLAB对图像进行频率域的平滑和锐化处理的简单例子(Application of MATLAB in frequency domain image smoothing and sharpening the handle of a simple example)

通过对主从系统的数学建模并利用matlab随机试验模拟，研究主从多机通信系统的可靠性，以及采用不同措施预防和解决故障的可行性和统计规律。包括实验报告和源代码( Though the mathematical modeling of the master-slave system and the random experiment with Matlab, we tried to research about the reliability of the system with or without different methods to prevent and solve the failure of the system, therefore we find some statistical regularity. )

Twelve pulse converter for a single cycle of input twelve pulse will be available in output... simulation circuits..

减摇水舱对船舶参数横摇的抑制，4自由度模型，包括垂荡‘纵摇和水舱状态(The anti rolling tank on the inhibition of Parametric Rolling of ships, model of 4 degrees of freedom, including heave pitching and water tank to state )

功能描述： 小数延迟FIR滤波器，对参考阵元信号signal_ref进行 length(tau) M次延迟，分别得到M个阵元的采样信号 关键问题： 若τ 1.2Ts,则Delay(i) 2,tau_valid(i) 0.2Ts 若τ 0.6Ts,则Delay(i) 1，tau_valid(i) -0.4Ts 当tau_valid(i)>0或<0时，从卷积后的数据y_FIR_delay中取值启示位置不同 函数能够实现输入任意延时tau，输出信号波形与理想波形之间误差很小。( Description: fractional delay FIR filter array element of a reference signal signal_ref performed length (tau) M delay times, respectively, to obtain a sample signal array element M key question: if τ 1.2Ts, then Delay (i ) 2, tau_valid (i) 0.2Ts if τ 0.6Ts, then Delay (i) 1, tau_valid (i) - 0.4Ts when tau_valid (i)> 0 or < 0, the volume data y_FIR_delay product after the Enlightenment values at different positions function can be realized enter any delay error between tau, the output signal waveform and the ideal waveform is small.)
