只要输入信号的中心频率和带宽，自动生成带通滤波器采样率、信号保护带、采样率误差容限(Just enter the center frequency and bandwidth of the signal, automatically generated bandpass filter sample rate, signal protection zone, the sampling error margin rate)

说明：  与常规的单目标遗传算法求解不同，该算法考虑两个目标函数的遗传算法(Different from the conventional single objective genetic algorithm, this algorithm considers the genetic algorithm of two objective functions)

边缘提取 算子 对初学者有一定参考价值 (edge extraction operator For beginners have a certain reference value)

建立一种可以区分输入图形的形态学算法，算法的输入是这三种图形的一种（这三个图形是对湖、湾、路段的图像细化后的结果），输出是对这三种图形的识别。假设这三种图形都是1个像素宽且完全连通的，然而它们出现的方向可以是任意的。 (Graphics can be imported to create a distinction between the morphological algorithm, algorithm input is a three graphics (which is three graphics Lake, Bay, after the section of the results of image thinning), the output is on these three graphics recognition. Assume that these three are one pixel wide graphic and fully connected, but they appear to be any direction.)

本代码有详细的注释，给出了采用CNN方法检测道路的程序，并给了测试图片！(This code has detailed notes, gives way to detect the use of CNN programs, and to a test picture!)
