Neural network simple example

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
