首先，你所下载的opencv与opencv_contrib一定要版本一致！！！注意：不要直接使用从官网上clone下来的opencv_contrib-master。不然的话会导致很多编译错误。之前我就一直使用opencv_contrib-master和opencv3.4.1一起编译，结果一直出错，然后网上又有大量的博客告诉你怎样解决，结果发现都是在扯淡，都是在误导人。你只需要opencv和open...

gray = cv2.bilateralFilter(gray, 11, 17, 17)双边滤波器（Bilateral filter）是一种可以保边去噪的滤波器。可以滤除图像数据中的噪声，且还会保留住图像的边缘、纹理等（因噪声是高频信号，边缘、纹理也是高频信息，高斯滤波会在滤除噪声的同时使得边缘模糊）。那这么优秀的一个滤波器，他到底是个什么呢，其实，它和我们普通的高斯滤波器一样，也是使用一个卷...
