WebSmoothing (Blurring) by Gaussian. This is the most commonly used blurring method. We can use this filter to eliminate noises in an image. We need to very careful in choosing the size of the kernel and the standard deviation of the Gaussian distribution in x and y direction should be chosen carefully. Here is the code using the Gaussian blur:
