窄带信号的DOA估计，MUSIC算法程序(DOA estimation of narrowband signals ，MUSIC algorithm)

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！(a watermark sourcecode implemented by MATLAB. By using this program, primary image can be embedded while the watermark cannot be extracted.)

这个函数估计到库默尔与第N系列的广义超几何微分方程解的权力。库默尔的差分方程为： x *的克 （十）+（二- X）的*克 （​ ​ x）的- A *的为g（x）= 0 该代码只有4线长，利用Matlab的向量运算有权采取了第N广义超几何级数的权力的总和。(This function estimates the solution to kummer s differential equation with the first N powers of the generalized hypergeometric series. Kummer s differential equation is given by: x*g (x)+ (b- x)*g (x)- a*g(x) = 0 The code is just 4 lines long, using the power of Matlab s vector operations to take the sum over the first N powers of the generalized hypergeometric series.)

有信道编码，调制，信道估计等，可以得到很精确的幅值、频率、相位估计，应用小区域方差对比，程序简单。( Channel coding, modulation, channel estimation, You can get a very accurate amplitude, frequency, phase estimation, Application of small area variance comparison, simple procedures.)

使用Matlab代码和Simulink做音频的滤波后傅里叶分析及相应滤波器分析(Using MATLAB code and Simulink to do fitlered audio file Fourier anlysis and specifications anlysis of the corresponding filter.)

说明：  在matlab环境下仿真随机信号，括号内为内容（正弦信号、白噪声信号、正弦信号附加白噪声三种信号形式） 的代码，计算该随机信号的相关函数和功率谱(In the matlab simulation environment, random signals, the contents of brackets (sinusoidal signal, white noise signal, sine wave signal form of three additional white noise) code, the calculation of the random signal correlation function and power spectrum)

说明：  基于GVF Snake模型与椭圆肤色模型融合的 手势轮廓检测方法 (GVF Snake model based on skin color model with the elliptical contour integration of gesture detection method)

基于迭代法自动阀值分割matlab源文件，不使用matlab自带的库函数！！！(Iterative method based on image segmentation)
