This will blur the image in a horizontal direction. You can pick any direction and it will work accordingly. The amount of blurring will depend on the size of the kernel. So, if you want to make the image blurrier, just pick a bigger size for the kernel. To see the full effect, we have taken a 15x15 kernel in the preceding code.
