-To further improve edge visibility, we can first smooth out the noise by convolving the original image with a Gaussian filter. To generate one with dimensions <i>n &times; n</i>, we can take the outer product of 2 length <i>n</i> arrays. Below is the result of blurring the original image using a 5 &times; 5 Gaussian filter:
