Lecture 3: Antialiasing (41)

I noticed that in most of these examples that in the frequency domain, the points are symmetrical across the x and y axis. What would happen here if we removed one of the grey dots (the left one, for example) and ran inverse FT?


If you have a non-symmetric frequency domain, then what'll happen is that your results in the spatial domain will have some imaginary components, so I'm not sure how that would actually get represented as an image.
