Yeah, but there are classical algorithms with tunable sharpening that are cheaper and widely known (e.g. catmull-rom or the "magic" kernel sharp algorithm by John Costella). My suspicion is that none of this mattered though, because the evaluation was probably "perceptual equivalence" vs bitrate. I can easily believe it might be a marginal win over traditional algorithms from that perspective. |
