Question to compare waifu2x and anime4k

[Daijobou]

Wow... this two algorithm are insane. I compiled anime4kcpp on ubuntu with windows 11 (wsl) and compared it with waifu2x.
Waifu2x its a little bit better (sharper, more details), so I wonder, is there a way for better output with anime4k or in this case waifu2x is a little bit better?

Maybe you miss the differences, here marked with red. Waifu2x show more details. Anime4k is a little blurred.

I don't see any option to improve the quality further. Am I missing something? I don't have a GPU.
Can anyone help me out here? Thanks! :)

And one more question.
Here https://github.com/TianZerL/Anime4KCPP#result is right side a "Origin HR" image. What this means? Where does that come from? I don't see any setting for this.

It is expected that Anime4KCPP is not as good as Waifu2X. The former aims at real-time processing, which means that the amount of CNN's parameters is much less. If you only want to get a high-quality single image instead of videos, I would suggest you use Waifu2X or more complicated algorithm.
Origin HR literally means "Origin High Resolution Image", it's the the target of processing.

Thanks for your fast response. So there is no way to make the image a little sharper with the help of additional filters?
Anime4KCPP its super good and ultra fast. Its needed on my notebook 0.2 seconds to create this image with Anime4KCPP. Even double the time would be fine for me.
Great work!

If you want sharper image, don't enable HDN (without '-L' option). Excessive noise reduction will make the image lack of detail.
And I will recommend you waifu2x-ncnn-vulkan for single anime image processing.
