learning matlab to use it properly

MeanShift运动目标跟踪 matlab程序 思路： 1.截取跟踪目标矩阵rect 2.求取跟踪目标的加权直方图hist1 3.读取视频序列中的一帧， 先随机取一块与rect等大的矩形，计算加权直方图hist2。 4.计算两者比重函数，如果后者差距过大， 更新新的矩阵中心Y，进行迭代（MeanShift是一种变步长可以迅速接近概率密度峰值的方法），直至一定条件后停止。 (MeanShift moving target tracking matlab program ideas: 1. Interception target tracking matrix rect 2. Strike target tracking weighted histogram hist1 3. Reading of a video sequence, first randomly selected one with such a large rectangle rect, calculate the weighted Histogram hist2. 4 Calculate the proportion of both functions, if the latter gap is too large, updated new matrix center Y, iterative (MeanShift is a variable step size can rapidly approaching the peak of the probability density method), until certain conditions stop.)

通过MATLAB中的GUI编程，绘制出戴维南定理的GUI界面并绘制相应的曲线(Through the GUI in MATLAB programming, drawing out the GUI interface and Thevenin s theorem to draw the corresponding curve)

利用MATLAB编程实现数字滤波器的功能(Digital filters using MATLAB programming functions)

将一个被小波包分解的矩阵变成小波结构，根据最高的分解层次，将原图3*level+1块分开赋给矩阵以便单独操作，按从上到下，从左到右的顺序(A matrix of wavelet packet decomposition into wavelet structure, according to the highest level of decomposition, the original 3* level+1 block separately assigned to the matrix in order to operate independently from top to bottom, from left to right order)

在图像处理中使用的穷尽算法对目标帧经行预测，也是运动估计的简单形式(In the end image processing algorithms used by the line on the target frame predicts a simple form of motion estimation is)

用matlab对2fsk信号进行调制和解调(2fsk signal using matlab on the modulation and demodulation)

说明：  中值滤波是图像预处理中的一种较常用的方法， 它能有效去除椒盐噪声等的影响。(The median filter is the image preprocessing of a more common method, it can effectively remove the impact of salt and pepper noise.)

说明：  802.11b中CCK11M,CCK5.5M的实现程序，解调用的是FWT算法。(Implementation of 802.11b in the CCK11M program solution is called FWT algorithm.)

说明：  用matlab实现的曼彻斯特编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的郭文斌的通信原理课件上的形状一模一样。(Manchester encoding with a matlab implementation. 50 duty cycle (adjustable). Draw time-domain waveform and frequency domain power spectral density. The results with the Beijing University of Posts and Telecommunications of the GUO of communication theory on the shape of the same courseware.)
