Figure 1: Tiling recursive filters exposes parallelism and locality in what are otherwise strictly-ordered computations
Figure 2: Tradeoff between different overlapping options for 3rd order Gaussian filter
Figure 3: Single 1D filter. (a) Naive sequential computation. (b) We transform it into a tiled scheme to improve performance
