- Colab Demo for Real-ESRGAN

- Portable Windows / Linux / MacOS executable files for Intel/AMD/Nvidia GPU. You can find more information here. The ncnn implementation is in Real-ESRGAN-ncnn-vulkan.
Thanks for your interests and use:-) There are still many problems about the anime/illustration model, mainly including: 1. It cannot deal with videos; 2. It cannot be aware of depth/depth-of-field; 3. It is not adjustable; 4. May change the original style. Thanks for your valuable feedbacks/suggestions. All the feedbacks are updated in feedback.md. Hopefully, a new model will be available soon.
感谢大家的关注和使用:-) 关于动漫插画的模型，目前还有很多问题，主要有: 1. 视频处理不了; 2. 景深虚化有问题; 3. 不可调节, 效果过了; 4. 改变原来的风格。大家提供了很好的反馈。这些反馈会逐步更新在 这个文档。希望不久之后，有新模型可以使用.
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.
🎨 Real-ESRGAN needs your contributions. Any contributions are welcome, such as new features/models/typo fixes/suggestions/maintenance, etc. See CONTRIBUTING.md. All contributors are list here.
❓ Frequently Asked Questions can be found in FAQ.md (Well, it is still empty there =-=||).
🚩 Updates
- ✅ Add the ncnn implementation Real-ESRGAN-ncnn-vulkan.
- ✅ 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 withLANCZOS4). 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 😃). It will be continuously updated in my spare time.
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 strength
If 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:stuck_out_tongue:). If necessary, I will open a page to specially record these real-world cases that need to be solved, but the current technology is difficult to handle well.
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
- Please refer to Real-ESRGAN-ncnn-vulkan for more details.
- Note that it does not support all the functions (such as
outscale) as the python scriptinference_realesrgan.py.
Usage: realesrgan-ncnn-vulkan.exe -i infile -o outfile [options]...
-h show this help
-v verbose output
-i input-path input image path (jpg/png/webp) or directory
-o output-path output image path (jpg/png/webp) or directory
-s scale upscale ratio (4, default=4)
-t tile-size tile size (>=32/0=auto, default=0) can be 0,0,0 for multi-gpu
-m model-path folder path to pre-trained models(default=models)
-n model-name model name (default=realesrgan-x4plus, can be realesrgan-x4plus | realesrgan-x4plus-anime | realesrnet-x4plus)
-g gpu-id gpu device to use (default=0) can be 0,1,2 for multi-gpu
-j load:proc:save thread count for load/proc/save (default=1:2:2) can be 1:2,2,2:2 for multi-gpu
-x enable tta mode
-f format output image format (jpg/png/webp, default=ext/png)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.
