Real-ESRGAN
 .
Portable Windows / Linux / MacOS executable files for Intel/AMD/Nvidia GPU. You can find more information here.
Real-ESRGAN aims at developing Practical Algorithms for General Image Restoration. We extend the powerful ESRGAN to a practical restoration application (namely, Real-ESRGAN), which is trained with pure synthetic data.
 Add RealESRGAN_x4plus_anime_6B.pth, which is optimized for anime images with much smaller model size. More details and comparisons with waifu2x are in anime_model.md
Support finetuning on your own data or paired data (i.e., finetuning ESRGAN). See here
Integrate GFPGAN to support face enhancement.
Integrated to Huggingface Spaces with Gradio. See Gradio Web Demo. Thanks @AK391
Support arbitrary scale with --outscale (It actually further resizes outputs with LANCZOS4). Add RealESRGAN_x2plus.pth model.
The inference code supports: 1) tile options; 2) images with alpha channel; 3) gray images; 4) 16-bit images.
The training codes have been released. A detailed guide can be found in Training.md.

We have provided a pretrained model (RealESRGAN_x4plus.pth) with upsampling X4. Note that RealESRGAN may still fail in some cases as the real-world degradations are really too complex. Moreover, it may not perform well on human faces, text, etc, which will be optimized later. Real-ESRGAN will be a long-term supported project (in my current plan Here is a TODO list in the near future: optimize for human faces optimize for texts optimize for anime images support more scales support controllable restoration strengthIf you have any good ideas or demands, please open an issue/discussion to let me know.
If you have some images that Real-ESRGAN could not well restored, please also open an issue/discussion. I will record it (but I cannot guarantee to resolve it You can download Windows / Linux / MacOS executable files for Intel/AMD/Nvidia GPU. This executable file is portable and includes all the binaries and models required. No CUDA or PyTorch environment is needed. You can simply run the following command (the Windows example, more information is in the README.md of each executable files): ./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.pngWe have provided three models: realesrgan-x4plus (default) realesrnet-x4plus realesrgan-x4plus-anime (optimized for anime images, small model size)You can use the -n argument for other models, for example, ./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n realesrnet-x4plus Note that it may introduce block inconsistency (and also generate slightly different results from the PyTorch implementation), because this executable file first crops the input image into several tiles, and then processes them separately, finally stitches together. This executable file is based on the wonderful Tencent/ncnn and realsr-ncnn-vulkan by nihui.  Dependencies and Installation
Python >= 3.7 (Recommend to use Anaconda or Miniconda)
PyTorch >= 1.7
