求图像的信噪比函数及峰值信噪比函数 很有用(Demand function is useful for image signal to noise ratio)

电网同步跟踪技术，自己搭的锁相环,可以运行出来。有频率跟踪，还有正负序分离(Grid synchronization tracking technology, take their own phase-locked loop, you can run out. There is frequency tracking, there are positive and negative sequence separation)

用Matlab语言实现通信系统的蒙特卡罗方法(Communication systems using Matlab language of Monte Carlo)

用matlab，根据要求输出特定的pattern，作为相机标定用(Using matlab, according to the specific requirements of the output pattern, as the camera calibration with)

以单相光伏发电并网系统为研究对象，针对光伏发电并网技术，深入分析了光伏发电最大功率点跟踪技术和逆变器并网控制技术。在Simulink中搭建了光伏电池模型、基于扰动观测法的MPPT模型和使用电压电流双闭环SPWM控制策略来并网。(Taking the single-phase photovoltaic power grid system as the research object, aiming at the photovoltaic power grid technology, this paper analyzes the maximum power point tracking technology and inverter grid control technology. In Simulink, photovoltaic cell model, MPPT model based on disturbance observation method and voltage current double closed-loop SPWM control strategy are built.)

一个非常有用的小波边缘检测源代码，matlab7a测试通过。(A useful source of wavelet edge detection, matlab7a tests pass.)

该方法通过原始象素亮度与周边象素亮度之间的关系获取增强系数，对已做全局亮度调整的图像进行图像增强(lum_en_local=wjli_lum_en_local_bilateral(lum_en_global,lum_ori,window_r,sigmad,sigmar))
