pso算法。pso算法的优化，有助于在现代工程中选择合适的路径，为只能算法的一种。(hough bianhuan)

用esprit方法估计功率谱，并估计信号频率和峰值(To esprit methods estimate the power spectrum, and estimate the signal frequency and peak)

将信号用小波函数SYM5分解到第5层，用minimaxi阈值选择对系数进行处理，消除噪声(SYM5 decomposition using the wavelet function signals to the fifth floor, use minimaxi threshold choice to deal with coefficient, eliminate noise)

阀值去噪 用db1小波对原始信号进行3层分解并提取系数(Db1 wavelet threshold de-noising with the original signal decomposition and extraction coefficient of 3 layers)

说明：  最优化 LM算法, 实现二次函数为目标函数的非线性优化(L-M Optimization method)

使用Kalman滤波实现二维图像中目标的轨迹跟踪(Two-dimensional images using Kalman Filtering Target tracking in)

提供了比较流行的人脸识别算法源代码，非常适合实验仿真(a very useful tool for face reconizer)
