以数字图像处理中的两种典型噪声，即椒盐噪声和高斯噪声为处理对象，根据典型滤波去噪算法，利用Matlab软件进行分析处理-Two typical noise in digital image processing, that is salt and pepper noise and Gaussian noise was treated as object of study in this paper, Matlab software was used for analysis and processing on the basis of the typical filtering denoising algorithm.
