说明：  在神经网络中，用四阶统计量的方法对图像进行特征提取(In the neural network, using fourth-order statistics of the image feature extraction method)

说明：  能够实现在导出CST方向图的情况下在MATLAB里面作阵列综合(Can achieve in the export of CST direction map in the case of MATLAB for array synthesis)

Part of a book I am writing on mechanical vibrations.

采用数据拟合法进行的高斯白噪声信道下的信噪比估计，程序中有经典summer法以及本人自己拟合的二阶和三阶参数，适用于不同的信噪比范围，望大家一起交流(By data fitting of the Gauss white noise channel SNR estimation, the program in the classic summer method as well as my own fitting of the two order and three order parameters, applicable to different SNR range, hope everybody exchanges together)

本项目主要工作是对提供图片与库中图片进行颜色和纹理两方面的匹配。其中，颜色匹配直接用基于颜色RGB的直方图匹配，纹理匹配则是通过小波变换转换成频域值，然后用Canny算子计算总和，最后得到图片的纹理图进行匹配(The main work of this project is to match the colors and textures to provide pictures and picture in the library. Among them, the direct use of color matching based on the color RGB histogram matching, texture matching wavelet transform converted into frequency domain values​ ​ , calculate the sum of the Canny operator, and finally get the picture of the texture map to match )

用于matlab sbm计算的代码，直接替换数据即可(for sbm(dea) in matlab)

说明：  这是用matlab的m文件编写的fir滤波器程序(this is a fir Filter)
