GLSL (v2.1 Stable)
Installation Instructions for GLSL/MPV Version
Integrated a pre-scaler in Anime4K. It is a tiny ConvNet (916 parameters, 3 hidden layers of 4 feature maps) trained with the differentiable Anime4K algorithm and other techniques that will be published soon. For comparison, FSRCNNX has more than 3000 parameters (depending on the version) and waifu2x has more than 1 million.
This pre-scaler gives a major quality improvement to lower resolution anime, especially for 720p and 480p.
480p -> 1080p, 480p -> 4K and 720p -> 4K are now officially supported.
Texture loss and aliasing issues are again reduced.
The pre-scaler uses 1.5ms for 1080p -> 4K upscaling, bringing the total to 4ms on a Vega 64 GPU.
