对分别添加了椒盐噪声（密度为0.03）和高斯白噪声（均值为0，方差为0.02）的图像，利用三种方法进行去噪，显示原始图像、加噪图像和去噪图像并对实验结果进行分析。-Were added to the salt and pepper noise (density 0.03) and Gaussian white noise (zero mean and variance 0.02) images, using three methods noising, shows the original image, increase noise and image denoising image and results analysis.
