Given the following image, 11 8 7 10 11 15 19 14 15 12 20 17 18 15 11 21 22 21 19 17 22 23 25 54 22 calculate the gradient in x and y using Sobel kernels (please normalize your result by 8). You may skip the borders of the image or assume zero padding. Then compute the gradient magnitude. You can insert your own matrix data using the "Table" tool in Canvas. You may use Python to verify your answer, but you must also write out the step-by-step calculations used to obtain your answer for at least one pixel in your image.
