That’s again the same issue. Nice theory, and theoretically is true, but all real algorithms also subsample high frequencies, and scale them back up with neares

That’s again the same issue. Nice theory, and theoretically is true, but all real algorithms also subsample high frequencies, and scale them back up with nearest-neighbor.
The same issue happens with audio. Nice theory, completely broken realistic implementations.
- astrange 9y agoIt's true that nearest neighbor is bad, but the important part is the YUV->RGB conversion. It distributes the missing high frequencies out of the Y channel into all three RGB images.
