在MATLAB环境中，进行数字图像处理中常用到的小波函数系列之三(In the MATLAB environment, to carry out commonly used in digital image processing of the wavelet function series of three)

空间匹配滤波器的输出信号 2D波束方向图 不同扫描方向的波束方向切面图(Spatial matched filter output signal in Fig 2D beam scanning direction different from the direction of the beam section of FIG.)

说明：  fcm实现简单的数值分类，只要你重新定义数据矩阵，就可以直接进行分类。(FCM implements simple numerical classification, which can be directly classified as long as you redefine the data matrix.)

网上下载的一个分行的好的程序，可以让大家借鉴下(Download a branch of a good program, so that everyone can learn from the next)

该文件包含了标准正弦波通过莱斯信道的输入波形和输出波形(This file contains the standard sine wave by Royce channel input and output waveforms)

data with gps spectral function

APF的模型，采样ip-iq法进行谐波提取，PI控制作为补偿算法，三电平spwm作为调制方式，在网侧添加了LCL滤波，个人感觉效果还不错，准备再添加重复控制，在谐波提取方面采样DFT来尝试(APF model, sampling ip-iq method for harmonic extraction, PI control as compensation algorithms, three-level spwm as modulation, the network side added a LCL filter, the effect of personal feeling good, ready to add a duplicate control, in harmony wavelet extraction areas to try sampling DFT)

永磁同步电机滑膜观测器估算电机转速。精度比传统观测器精度高。(Estimation of motor speed by permanent magnet synchronous motor. The precision is higher than that of the traditional one)

说明：  利用盲源分离原理的方法，可以实现多路信号的同时恢复。(The method of blind source separation can realize simultaneous recovery of multiple signals.)

A simple PSNR calculator that might be handy in measuring the PSNR between two frames in a video. Typically used in measuring the distortion when videos are encoded and decoded.
