Geometrically Verified Nearest Neighbors

Our full, unfiltered version of Figure 7, but using the network trained with the “projection” preprocessing to handle chromatic aberration rather than color dropping. That is, we sample constellations of four adjacent patches, find nearest neighbor images for the constellations, and geometrically verify them, as described in Section 4.4. We convert patches to grayscale before finding nearest neighbor images, since with color projection alone, we did find a small number of high-ranking constellations that had only chromatic aberration in common.
