现有三幅图像，图像1是包装瓶中的气泡图片，图像2是印刷电路板的元器件焊接质量检查图，图像3是封装后的胶囊状药品。实验要求从这三幅图片中，

1.　　选择一副图像，并叠加零均值高斯噪声，分别利用均值滤波和中值滤波器对该有噪图像进行滤波，显示滤波后的图像，比较两滤波器的滤波效果。

2.　　选择一副图像，并叠加椒盐噪声，分别用均值滤波器，中值滤波器对该图像进行滤波，比较滤波器的滤波效果。

3.　　选择一幅图像，分别利用Laplacian算子和Sobel算子对图像进行锐化操作，比较锐化的效果。-Three images, image packaging bottle of bubbles picture, image 2 printed circuit board components, welding quality inspection, the image is packaged in capsule form drugs. Experiments from these three pictures, select an image, and superimposed on the zero-mean Gaussian noise, respectively, the mean filter and median filter the noisy image filtering, display the image after the filtering, comparison of two filtering filtering effect of the device. 2 Select an image, and superimposed on the salt and pepper noise, respectively, the mean filter, median filter to the image filter, more filter filtering effect. Select the image, respectively, using the Laplacian operator and Sobel operator to image sharpening operation, more sharpening effect.
