说明：  基于OpenCV的二维图像加噪去噪C++程序，程序包含给图像添加高斯噪声功能，去噪方法有方框滤波、均值滤波、高斯滤波、中值滤波、双边滤波
(The C + + program of two-dimensional image denoising based on OpenCV includes the function of adding Gaussian noise to the image. The denoising methods include box filter, mean filter, Gaussian filter, median filter and bilateral filter)
