The rectangle in the binary image in the next page is of size m ×n pixels.

(a) What would the magnitude of the gradient of this image look like based on using the approximation given in Eq. (10.2-20)? Assume that gx and gy are obtained using the Sobel operators. Show all relevant different pixel values in the gradient image.
