Today we analyzed the frequency response of the average filter discussed in the [[Lecture36ECE438F13|previous lecture]]. More specifically we computed its discrete-space Fourier transform and looked at [[ECE_438_Fall_2009_mboutin_plotCSFTofbasicfilters|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. | Today we analyzed the frequency response of the average filter discussed in the [[Lecture36ECE438F13|previous lecture]].

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.
ANNOUNCEMENT: The solution of HW10 is wrong. The first student to post a correct solution will get a 1% bonus. (Post your solution below the other one.)
