[Q] How do I apply Anime4k GLSL filters on images? #238

Open NightMachinery opened 4 months ago

I want to upscale images (e.g., PNG files) using Anime4k GLSL shaders such as https://github.com/bloc97/Anime4K/blob/master/glsl/Upscale%2BDenoise/Anime4K_Upscale_Denoise_CNN_x2_L.glsl. Is this possible?

If you got a 4K display, just drag and drop image into mpv and take screenshot.

Otherwise just use waifu2x for image.

@Tama47 I actually want to use this for slide images extracted from lecture videos, not anime. Anime4K filters make the slides look better on mpv, and I don't really know of another option. Do you still recommend waifu2x?

I also need the process to be automatable, so manual screenshotting is not good.

Yes, you can batch upscale all the images at once, just be sure to use the Anime4K models as other models can take considerably longer to upscale.

yes, you can use the new filter in ffmpeg called "libplacebo" to use glsl on video stream or just a single image. see at :https://stackoverflow.com/questions/76792577/how-to-use-ffmpeg-to-upscale-video-resolution-with-libplacebo/76793322#76793322
