Is it possible to add "jinc" to the image upscaling setting? #21

Closed yeezylife closed 3 years ago

yeezylife commented 3 years ago

Jinc could be a interesting choice for image upscaling.

1 - There are examples of this algorithm on shaders? 2 - There is a comparison of this algorithm with others?

yeezylife commented 3 years ago

I've been using jinc in Madvr,it's just slightly less sharp than lanczos3 , but have much less ringing. Comparison can be found inhttps://forum.doom9.org/showthread.php?t=146228&page=718

Is there open source implementation ?

https://github.com/AviSynth/jinc-resize https://github.com/Asd-g/AviSynth-JincResize https://github.com/AviSynth/jinc-resize/tree/master/JincResize I searched on github and found these..

We use shaders - i don't think that we can write it based on c++ code.

How about these,sorry I'm not a coder. https://forums.libretro.com/t/jinc-2-fixes/21146/5 https://pastebin.com/raw/fH2A3Y42 https://git.libretro.com/libretro-assets/glsl-shaders/-/blob/master/nedi/shaders/nedi-jinc.glsl

Thanks. This is a shader for GLSL. Someone needs to understand it, translate it into HLSL and adapt it to our environment. I don't plan on doing this anytime soon.

Added in 9ce801a59499c3f182ca294cb92b57de246a7522. The status of this resizer is experimental. I'm seeing some distortion at large scales. If you know how to fix this, please write.
