The reason that the way of calculating the total variance is a good
qualitative method of describing how the image is affected with the added
noise, is that the output of the total variance formula is describing how
the value of the pixels of the image were close to each other.
This was done through summation of the average variance in a window of 3X3
pixels. The calculation begins with getting the average value of the pixels
in the 3X3 window. Then seeing how the pixels values in the window are
close to the average value by subtracting each pixel in the window by
