3 by 3 spatial low pass mask (averaging filter) to f(x,y). Similarly let g(x,y) be the image
obtained by applying a 3 by 3 spatial high pass mask to f(x,y). Prove that
g(x,y) = f(x,y) - h(x,y)
Note: One or more examples do not constitute a proof.
(b) [5 points] Is the high pass mask separable? What is the implication of separability on
computations?
