Compute the following:
(a) The output of correlation of h=[1 1 0] and the first row. Assume the first row as 1-D image.
(b) The output of convolution of h=[1 1 0] at (0,0). Assume the first row as 1-D image.
(c) The output of a 3 × 3 mean filter at (2,2).
(d) The output of a 3 × 3 median filter at (2,2).
(e) The output of the 3 × 3 Laplacian filter shown above at (2,2).
