Real-ESRGAN 是什么？
Real-ESRGAN is the widely used super-resolution model behind many upscalers. It ships portable NCNN/Vulkan executables for Windows, macOS and Linux as well as a Python package, with models for general photos and anime.
主要功能
- General and anime-specific upscaling models
- Portable executables — no Python needed
- Optional face enhancement via GFPGAN
- Video frame upscaling
系统要求
- 平台
- Windows · macOS · Linux
- 显卡
- Vulkan GPU for the portable build; NVIDIA for the PyTorch version
如何安装 Real-ESRGAN
根据项目 README 整理。开源项目更新很快，请以 GitHub 页面上的最新说明为准。
Portable executable
- 1Download realesrgan-ncnn-vulkan for your OS from GitHub Releases and extract it.
- 2Upscale an image.
./realesrgan-ncnn-vulkan -i input.jpg -o output.png -n realesrgan-x4plus
Python
- 1Clone and install.
git clone https://github.com/xinntao/Real-ESRGAN.git cd Real-ESRGAN pip install basicsr facexlib gfpgan pip install -r requirements.txt python setup.py develop - 2Run inference on a folder.
python inference_realesrgan.py -n RealESRGAN_x4plus -i inputs --face_enhance
优势
- Fast and reliable
- Permissive license
不足
- Can over-smooth fine textures
- Python install has dependency quirks
