Today we analyzed the frequency response of the average filter discussed in the previous lecture. More specifically we computed its discrete-space Fourier transform and looked at its plot. Using the separability of the filter greatly facilitated the computation of its Fourier transform. We discussed different ways to determine whether a filter is separable and how to separate it. We then considered another filter (edge detector). Although that filter is not separable, we were able to write it as a sum of two separable filters.
