(a) Show that Fourier transform of a Gaussian function is also a Gaussian function. (b) Consider a 3 x 3 spatial mask that averages the four closet neighbors of a point (x,y) but excludes the point itself from the average. Calculate equivalent filter H(u,v) in frequency domain. (c) Calculate the equivalent filter H(u,v) that implements in the frequency domain the spatial operations performed by Laplacian mask
