数字通信系统中，基于MATLAB的几种常见信号的仿真(Digital communication system, based on several common signal MATLAB simulation)

an inferior assistant or a channel administrator hopes to append some additional message, such as the origin information, image notation or authentication data, within the encrypted image though he does not know the original image content. some parameters are embedded into a small number of encrypted pixels, and the of the other encrypted pixels are compressed to create a space for accommodating the additional data and the original data at the positions occupied by the parameters

使用MATLAB编程，求非线性方程组的根。本例为三个参数的非线性方程组。(Using the MATLAB programming, seeking the roots of nonlinear equations. In this case, there are three parameters.)

对实时视频数据做二值化处理，实现目标分离跟踪检测，实现计数。通过对目标特征点连续多帧跟踪，利用最小二乘法实现测速。(traffic 凑难听)

FDTD仿真，空气和玻璃界面的折射现象，可以观察到电磁波的折射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor. )
