matlab数字水印 通过这个程序可以给原图象加上水印 但不可以提取！(Matlab digital watermarking through this procedure can be added to the original image watermark but not extract!)

code for averaging,ORing,ANDing images

这个是对于fir带通滤波器以及iir低通滤波器的一个仿真。程序代码通俗易懂，意义很大。(This is a band-pass filter and the fir iir low-pass filter with a simulation. Program code easy to understand, very meaningful.)

matlab程序求图像的梯度，获得图像的纹理信息丰富的点或边缘点、角点等。(to get the gradient of mage, the image texture information rich points or edge, corner, etc.)

用MATLAB仿真取样光栅的传输特性，使用方法为传输矩阵法(MATLAB simulation of transmission characteristics with sampled grating, using the method of transfer matrix method)

利用自适应陷波器来消除通信系统中的工频干扰。重点从LMS算法的步长因子、信号与干扰的频率差、参考输入的幅值和相位等几个方面讨论单频陷波器的滤波效果。另外，还以双频为例，讨论了多频级联型陷波器的特性，证实了经过两次滤波后，信号可被真实的恢复出来，且误差收敛趋于稳定。(The use of adaptive notch filter to eliminate the communication system frequency interference. LMS algorithms focus from step factor, the frequency difference signal and interference, refer to the input amplitude and phase of discussions on several aspects of single-frequency notch filter of the filtering effect. In addition, in order to dual-band, for example, discussed the multi-frequency cascade notch filter characteristics, confirmed the filtered twice, the signal can be restored out of true, and the error convergence stable.)

不考虑不平衡磁拉力（UMP），转子系统在自身的质量、阻尼、弹簧等作用下，轴心轨迹求解方法(unbalanced magnetic pull is not considerated and rotor center orbit is gotten)

关于永磁同步电机DTC系统的无速度传感器，效果还可以(On permanent magnet synchronous motor DTC system without a speed sensor, the effect can also be)

data mining k nearest neighbour

本文档包括，BA_net.m、WS_net.m和randomgraph.m是可以直接运行的文件，分别生成三种不同网络的网络模型和特性曲线等，以及一个说明文档(This document includes: BA_net.m, WS_net.m and randomgraph.m file can be run directly, namely generation network model and characteristics of three different networks and so on. )
