形状检测和计数用 matlab 编写了

利用patchwork方法，嵌入0-1水印。可设置像素修改值、选择各种经典的攻击方式和控制攻击强弱。返回提取的水印信息和峰值信噪比。利用Matlab编写。(The use of patchwork approach, embedding the watermark 0-1. Modify pixel values can be set to choose a variety of classic attacks and control the strength of the attack. Back to extract the watermark information and peak signal to noise ratio. Prepared using Matlab.)

基于RSSI的无线传感器网络定位，此算法实现RSSI定位(RSSI-based localization for wireless sensor networks)

连续的PLL锁相，大家多交流！迫切希望大家交流！(consecutive PLL lock-in, we exchange more! Eager to share!)

应用MATLAB程序求解轴向受力的板结构在静力荷载作用下的单元应力、节点位移和约束反力(Using MATLAB to solve the axial stress of plate structure under static load of unit stress, node displacement and constraint counterforce)

通过蚁群算法改进PID控制器的参数，找到合理的组合，并进行轨迹跟踪(The parameters of the PID controller are improved by ant colony algorithm to find a reasonable combination and track it.)

基于Pisarenko谐波分解的间谐波估算方法。自己编写的程序，可直接运行。(Based Pisarenko harmonic decomposition between harmonic estimation methods. The programs that can be run directly.)

表示出两帧图像间各个像素点的相对情况，这个有中文注释，看得明白，使用拉亚普诺夫指数的公式，是小学期课程设计的题目，用于信号特征提取、信号消噪，预报误差法参数辨识-松弛的思想。

内部资料，很经典的MIMO和OFDM的课本程序，以供大家参考(it is important MIMO-OFDM program)
