Really glad to see they included Lanczos. It's extremely frustrating to those in the know to see comparisons that only use subpar algorithms. The worst only use a B-spline or nearest-neighbor upscale, and end up looking like one of those eyeglass prescription ads for seniors. Something like Lanczos is the minimum acceptable, I think.
Adobe's bicubic produces obvious severe artifacts, I assume it's something like a Catmull-Rom spline cubic.
