b) Using the given p and q maps shown in the tables below, and the z map at a specific iteration shown in an adjacent table, compute z value at the central pixel site in the subsequent iteration in the relaxation algorithm based on Euler- Lagrange formulation. You may use a value of 0.01. Assume your algorithm uses Sobel's method for finding derivatives p, and q, once for all, but adopts a simple way of calculating V2z = the simple formulas 8z Ox - Z + 0z Jz dx dy by using in each iteration @(i,j)=(AZ) AZ(-1)) = ((1+1)))-(Z)-(-1)) = (+1)-2() + 2(i)-1) and dy2 -1 @(i, j) = (A,Z)-A,2(-1)) = ((m.) -Z)-(Z)-(-1))=2(+1) - 22()) + 2(1-1) (5 Points 2 -2 2 1 3 2 3 1 5 -2 4 3 23 -1 3 1 2 4 1 -4 -5 -2 2 2 3 p-map q-map z-map at a specific iteration
