#12to me, hq4x looks better every time.
I was thinking that too, but then came to terms with 'ours' version
Re: Depixelizing Pixel Art
#13Are there any emulators that support this?
Re: Depixelizing Pixel Art
#14I wish they would use this in Windows 8. As far as I can tell, their scaling algorithm for 4k displays is: scale up 2x using nearest neighbor, then randomly drop pixels to get back to 125% or 150%. The result is horrifyingly bad. Not just kind of bad, but unusably bad. (Adding insult to injury, they ClearType the text before scaling.)

#15Does anyone know where I can find an implementation of this? I can't even figure out what to call it. They just refer to it as "our method."

#16I wonder why they all fall down on Peach and Peach 2? None of them look nearly as good (to me) as bicubic.

#18Boo is the best example of 'ours'. Looks amazing.
Re: Depixelizing Pixel Art
#19Is there a paper or code associated with this?

I would guess it's for performance reasons.
