Levenberg_Marquardt最优化算法matlab源程序(Levenberg_Marquardt optimization algorithm matlab source code)

图像拼接，利用简易算法完成拼接过程，可实现不同数量的图像以为拼接。所采用图例为最新一届全国数学竞赛图片。绝对原创(Image mosaic, complete the splicing process using simple algorithm, which can realize image splicing different number of thought. The legend for the new session of the national mathematics contest. )

一个三层的神经网络算法,可以用来数据拟合,建模.(A three-tier neural network algorithm can be used to data fitting, modeling.)

扩展功能的DFT，可以自动扩展输入序列X，如果你输入的长度不足N，会自动以NaN补足(Extension of the DFT, can be automatically extended input sequence X, if you enter a length less than N, will automatically fill in NaN)

说明：  数学实验与Matlab周晓阳老师，简单明了，易学易懂！(The mathematical experiment with Matlab Zhou Xiaoyang teacher, straightforward, easy to understand!)

Spread Spectrum Watermarking MATLAB

简单的仿真,在simulink里简单的创建了模型,然后练习使用传递函数(Simple simulation in simulink in the creation of a simple model, and then practice using the transfer function)

说明：  空域相关滤波是基于小波系数尺度之间相关性原理。 %比较适用于高信噪比信号(Spatial correlation filtering is based on the correlation principle between wavelet coefficient scales. % is more suitable for high SNR signals)

实现了小小去噪，与其他去噪方法相比取得了良好的效果(denoising based on wavelet)
