i need help for the Q3 below:

i have attached the rule in the second photo

(30 Marks) Find the results (the edge magnitude and direction) of applying both Sobel operator and the square root Roberts operator on pixel (1,1) in the following image. 25152530304520502022403510205020 6.2.1.2 The Sobel operator The Sobel operator approximates the gradient by using a row and a column mask, which will approximate the first derivative in each direction. The Sobel edge DigitalImageProcessing|Lecture6 Asst. Lec. Rajaa Hussein detection masks find edges in both the horizontal and vertical directions and then combine this information into two metrics - magnitude and direction. The masks are as follows: Verticaledge101202101121000121Horizontaledge These two masks are each convolved with the image. At each pixel location, we now have two numbers: s1, corresponding to the result from the vertical edge mask, and s2, from the horizontal edge mask. We use these numbers to compute two metrics, the edge magnitude and the edge direction, defined as follows: Edge magnitude: s12+s22 Edge direction: tan1[s2s1]
