变步长自适应滤波算法，对VS—LMS算法进行了改进，建立了步长因子μ与误差信号e（n）之间另一种新的非线性函数关系．理论分析和计算机仿真结果表明，该关系不仅具有原有算法收敛速度快的优点，而且在低信噪比环境下比原有算法具有更好的抗噪声性能．(The variable step size adaptive filtering algorithm is discussed, and the VS-LMS algorithm is improved. A new nonlinear function relation between the step size factor μ and the error signal e (n) is established. Theoretical analysis and computer simulation results show that the proposed algorithm not only has the advantages of high convergence speed of the original algorithm, but also has better anti- noise performance in the low SNR environment than the original algorithm.)

实现hmm基本算法。此代码实现基本的viterbi算法。有学习功能(The matlab code implements Viterbi algorith to realize HMM s learning.)

说明：  微弱信号的提取检测和分析 用matlab实现的源代码 首先计算输入信号的均值、均方值、方差、频谱及功率谱密度，确定输入信号中包含着有用信号。然后提取有用信号，并要求计算提取信号的均值、均方值、方差、概率密度、频谱及功率谱密度，并画出曲线(The extraction of weak signal detection and analysis)

自然图像中往往含有大量噪声，这些噪声可能服从一定的统计规律，因此可以采用顺序统计方法，对这些噪声加以剔除。(naturalimages always have lots of noise,and the noise may obey some statistical regularity，so we can use order statistic to get rid of the noise.)
