// Homework 2 | |
// Image Blurring | |
// | |
// In this homework we are blurring an image. To do this, imagine that we have | |
// a square array of weight values. For each pixel in the image, imagine that we | |
// overlay this square array of weights on top of the image such that the center | |
// of the weight array is aligned with the current pixel. To compute a blurred | |
// pixel value, we multiply each pair of numbers that line up. In other words, we | |
// multiply each weight with the pixel underneath it. Finally, we add up all of the | |
// multiplied numbers and assign that value to our output for the current pixel. |
