Refer to the image and structuring element shown. Sketch what the sets C, D,E,and F would look like in the following sequence of operations: C = A ⊖ B; D = C ⊕ B; E = D ⊕ B; and F = E ⊖ B. The initial set A consists of all the image components shown in white, with the exception of the structuring element B. Note that this sequence of operations is simply the opening of A by B,followed by the closing of that opening by B. You may assume that B is just large enough to enclose each of the noise components.
