implementation of feedforward neural network to recognize the faces with sunglasses from open faces.data source is from machine learning book by mitchell

这是一个关于图像处理的代码，对于图像处理特别是图像分割方面的学生，非常有用，希望你能狗狗帮助大家，希望大家有什么游泳的资源可以iyiqi分享一下 ，

十种软件滤波.rar介绍了十种软件滤波的方法,不过我建议还是使用模拟滤波方法好.(10 kinds of filtering software. Rar introduction of dozens of software filtering method, but I suggest that the use of analog filtering methods or good.)

《MATLAB/Simulink建模与仿真实例精讲》第9章相关例子程序，可以运行。(" MATLAB/Simulink modeling and the simulation example 精讲" Chapter 9 example program can run.)

在matlab环境下对Bayer图像格式融合由灰度图转化为彩图，对图像边缘的像素处理存在一些瑕疵，其他的都还可以，代码纯手工

基于多相结构的信道化接收机，进行逐步线性回归，计算多重分形非趋势波动分析matlab程序,LDPC码的完整的编译码，分形维数计算的毯子算法matlab代码,借鉴了主成分分析算法（PCA）。

说明：  一种基于RSSI的DV-HOP加权算法，该算法基于节点接收信标节点位置元组时的信号强度（RSSI）对邻居节点间跳数进行加权处理，将节点间的跳数与距离相关联，仿真试验结果证明该加权算法可大大提高定位精度。( a RSSI based weighted DV-HOP (RWDV-HOP) Localization algorithm is presented. In this algorithm the hops of adjacent node is weighted by the RSS of flooding packets transmitted between adjacent node. Our algorithm improves the localization accuracy compared with previous algorithms, which has been demonstrated by the simulating results.)
