2D脑图的L1小波重建图像，您需要安装Wavelab来实现此代码。(demo_Brain_2D.m demonstrate an L1-wavelet reconstruction of a brain image. )

多输入多输出的三层神经网络（反向传播算法）PID控制(Multi input multi output three layer neural network (back propagation algorithm) PID control)

matlab 图像边缘检测 可以对图片进行拉普拉斯边缘检测(matlab image edge detection)

说明：  基于RSSI的定位，已知发射节点的发射信号强度, 接收节点根据接收信号的强度, 计算出传播损耗, 利用理论的或经验的信号传播模型将传播损耗转化为距离, 然后再计算出节点的位置。(Based on RSSI positioning, the transmitting signal strength of the transmitting node is known, and the receiving node calculates the propagation loss according to the received signal strength. The propagation loss is converted into distance by using the theoretical or empirical signal propagation model, and then the position of the node is calculated.)

说明：  数字信号处理中最小二乘法对信号进行处理的程序编写(Least squares in digital signal processing the signal processing programming)

说明：  很强大，用于优化的算法，准确度高，速度快(Very good, algorithm for optimization, high accuracy, fast speed)

说明：  实现数字水印的嵌入，提取，以及受攻击后的提取(The realization of digital watermark embedding, extraction, and the extraction after attack)
