说明：  均值滤波对高斯噪声的效果 二维自适应维纳滤波对高斯噪声的滤除效果 对加入椒盐噪声的图像分别作均值、中值和维纳滤波 分别使用二维统计滤波对椒盐噪声和高斯噪声进行滤波 利用wrcoef2函数进行图像去噪
(Mean filter on the effect of Gaussian noise two-dimensional Adaptive Wiener filtering of the Gaussian noise filtering effect the image to join Salt and pepper noise, respectively for the mean, median and Wiener filtering respectively, using two-dimensional statistical filtering of the Salt & Pepper noise and Gaussian noise filter the use of image denoising wrcoef2 function)
