1. Consider the following three filters G, E and M. G is a Gaussian smoothing kernel, E is one of the linear kernels used by the Sobel edge detector and Mis a median filter. Is applying G to an image followed by E equivalent to applying E to an image followed by G? How about if Mis used in place of G? In both cases, explain your answer. 2 Drooth 1.
