In this project, we will be exploring how to implement a Gaussian Blurring program that will inherently alter each pixel of an image in order to take a new pixel value that will be affected by a pixel's surrounding neighbors.
A naive approach to “blurring” an image would be to visit each pixel take the greyscale value of the surrounding 8 pixels and average it with the current pixel. However, this strategy leads to a muddier and less appealing result and is often not used in the real world. Instead, a different approach, the Gaussian Blur, is more common in real-world applications such as Blender or photo editors.
