machine data processing part2

说明：  FIR数字滤波器的设计方法主要是建立在对理想滤波器频率特性作某种近似的基础上的。这些近似方法有窗函数法、频率抽样法、最佳一致逼近法。在这里只讨论窗函数法。程序中也是采用了这种方法。(FIR digital filter design method is mainly based on the frequency characteristics of the ideal filter for some kind of approximation on the basis of. These approximate methods are a window function method, frequency sampling method, the best uniform approximation method. Here only to discuss the window function method. Procedure is also adopted this approach.)

GPS接收数据中出现野值时的一种处理方法，较为简单易懂(A processing method of data outliers occur when the GPS receiver, the relatively straightforward)

用二维离散余弦变换(DCT)进行数字水印matlab源码(two-dimensional discrete cosine transform (DCT) digital watermarking Matlab FOSS)

Matlab编写的路标识别程序，可以对一幅图像中的多个路标进行识别。对雾化图片效果很好！(Matlab program written in road signs recognition, an image can be identified in a number of signs. Good effect on the atomization pictures!)

Gaussian Processes for classification

实现dtmf双音多频信号的matlab仿真编码和解码，采用coertzel算法。(Methods of measurement for pushbutton telephone with DTMF )

说明：  用MATLAB实现（7，3）循环码算法，很好的体现了循环码的特性(Using MATLAB implementation (7,3) cyclic code algorithm shows good characteristics of cyclic codes)

彩色图像批量转换为灰度图像并自动保存，刚刚写好的一个小程序(Batch convert color images to grayscale images and automatically save, just a small program written)

说明：  33节点配电网仿真模型，可用于电力系统分析，潮流计算、短路计算(33 nodes distribution network simulation model and can be used for power system analysis, power flow calculation, short circuit calculation)
