MATLAB图像处理中用到的命令语句和函数语句还包括一些编程举例。(MATLAB image processing functions used in the command statement and statements also include some programming examples.)

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

here to import the pictures and how to segment the picture. how to add the noise. some screen shots will be added this file.

这是一个使用matlab软件进行FSK信号仿真的程序，包括了FSK的解调和调制，希望有用。。。。(This is an FSK signal using matlab software simulation of the process, including the FSK demodulation and modulation, hope helpful. . . .)

图像变化检测算法，由t检验得到差分图像的变化掩膜。左后成功检测到图像中运动的物体。(Image change detection algorithms have been tested by the t change difference image mask. Left a successful campaign to detect objects in images.)

二维情况下用ＦＤＴＤ方法模拟电磁波的传播情况，加入了理想匹配层，用Ｃ和MATLAB混合编程，信号源是高斯脉冲(Two-dimensional case with the FDTD simulation of electromagnetic wave propagation, no additional absorbing boundary condition, mixed with the C and MATLAB programming, the signal source is a Gaussian pulse)
