Lecture 3: Sampling, Aliasing, Antialiasing (89)

After looking at various antialiasing implementations, I found one that I thought was especially interesting and applicable to the topics we’ve discussed in class. The approach itself is called Fast Approximate Anti-Aliasing (FXAA). This approach can be thought of in two steps. First, we find the edges of an image, ie the primary location of undesirable jaggies. We then antialias the edges, instead of the entire image. I figure one approach would be to perform a Fourier transform, apply an edge filter, then antialias the edges?
