我们提供了一套训练好的模型(*RealESRGAN_x4plus.pth*),可以进行4倍的超分辨率。<br>
|
|
**现在的 Real-ESRGAN 还是有几率失败的,因为现实生活的降质过程比较复杂。**<br>
|
|
而且,本项目对**人脸以及文字之类**的效果还不是太好,但是我们会持续进行优化的。<br>
|
|
|
|
Real-ESRGAN 将会被长期支持,我会在空闲的时间中持续维护更新。
|
|
|
|
这些是未来计划的几个新功能:
|
|
|
|
- [ ] 优化人脸
|
|
- [ ] 优化文字
|
|
- [x] 优化动画图像
|
|
- [ ] 支持更多的超分辨率比例
|
|
- [ ] 可调节的复原
|
|
|
|
如果你有好主意或需求,欢迎在 issue 或 discussion 中提出。<br/>
|
|
如果你有一些 Real-ESRGAN 中有问题的照片,你也可以在 issue 或者 discussion 中发出来。我会留意(但是不一定能解决:stuck_out_tongue:)。如果有必要的话,我还会专门开一页来记录那些有待解决的图像。

### 便携版(绿色版)可执行文件
|
|
|
|
你可以下载**支持Intel/AMD/Nvidia显卡**的绿色版exe文件: [Windows版](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-windows.zip) / [Linux版](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-ubuntu.zip) / [macOS版](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-macos.zip)。
|
|
|
|
绿色版指的是这些exe你可以直接运行(放U盘里拷走都没问题),因为里面已经有所需的文件和模型了。它不需要 CUDA 或者 PyTorch运行环境。<br>
|
|
|
|
你可以通过下面这个命令来运行(Windows版本的例子,更多信息请查看对应版本的README.md):
|
|
|
|
```bash
|
|
./realesrgan-ncnn-vulkan.exe -i 输入图像.jpg -o 输出图像.png -n 模型名字
|
|
```
|
|
|
|
我们提供了五种模型:
|
|
|
|
1. realesrgan-x4plus(默认)
|
|
2. reaesrnet-x4plus
|
|
3. realesrgan-x4plus-anime(针对动漫插画图像优化,有更小的体积)
|
|
4. realesr-animevideov3 (针对动漫视频)
|
|
|
|
你可以通过`-n`参数来使用其他模型,例如`./realesrgan-ncnn-vulkan.exe -i 二次元图片.jpg -o 二刺螈图片.png -n realesrgan-x4plus-anime`
|
|
|
|
### 可执行文件的用法
|
|
|
|
1. 更多细节可以参考 [Real-ESRGAN-ncnn-vulkan](https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan#computer-usages).
|
|
2. 注意:可执行文件并没有支持 python 脚本 `inference_realesrgan.py` 中所有的功能,比如 `outscale` 选项) .
|
|
|
|
```console
|
|
Usage: realesrgan-ncnn-vulkan.exe -i infile -o outfile [options]...
|
|
|
|
-h show this help
|
|
-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 (can be 2, 3, 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 the pre-trained models. default=models
|
|
-n model-name model name (default=realesr-animevideov3, can be realesr-animevideov3 | realesrgan-x4plus | realesrgan-x4plus-anime | realesrnet-x4plus)
|
|
-g gpu-id gpu device to use (default=auto) 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)
|
|
-v verbose output
|
|
```
|
|
|
|
由于这些exe文件会把图像分成几个板块,然后来分别进行处理,再合成导出,输出的图像可能会有一点割裂感(而且可能跟PyTorch的输出不太一样)
|
|

## :wrench: 依赖以及安装
|
|
|
|
- Python >= 3.7 (推荐使用[Anaconda](https://www.anaconda.com/download/#linux)或[Miniconda](https://docs.conda.io/en/latest/miniconda.html))
|
|
- [PyTorch >= 1.7](https://pytorch.org/)
|
|
|
|
#### 安装
|
|
|
|
1. 把项目克隆到本地
|
|
|
|
```bash
|
|
git clone https://github.com/xinntao/Real-ESRGAN.git
|
|
cd Real-ESRGAN
|
|
```
|
|
|
|
2. 安装各种依赖
|
|

# 安装 basicsr - https://github.com/xinntao/BasicSR
|
|
# 我们使用BasicSR来训练以及推断
|
|
pip install basicsr
|
|
# facexlib和gfpgan是用来增强人脸的
|
|
pip install facexlib
|
|
pip install gfpgan
|

python setup.py develop
|
|
```
|
|
|
|
## :zap: 快速上手
|
|
|
|
### 普通图片
|
|
|
|
下载我们训练好的模型: [RealESRGAN_x4plus.pth](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.0/RealESRGAN_x4plus.pth)
|
|
|
|
```bash
|
|
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.0/RealESRGAN_x4plus.pth -P weights
|
|
```
|
|
|
|
推断!
|
|
|
|
```bash
|
|
python inference_realesrgan.py -n RealESRGAN_x4plus -i inputs --face_enhance
|
|
```
|
|
|
|
结果在`results`文件夹
|
|
|
|

wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.4/RealESRGAN_x4plus_anime_6B.pth -P weights
|
|
# 推断
|
|
python inference_realesrgan.py -n RealESRGAN_x4plus_anime_6B -i inputs
|
|
```
|
|
|
|
结果在`results`文件夹
|
|
|
|
### Python 脚本的用法
|
|
|
|
1. 虽然你使用了 X4 模型,但是你可以 **输出任意尺寸比例的图片**,只要实用了 `outscale` 参数. 程序会进一步对模型的输出图像进行缩放。
|
|
|
|
```console
|
|
Usage: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile -o outfile [options]...
|
|
|
|
A common command: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile --outscale 3.5 --face_enhance
|
|
|
|
-h show this help
|
|
-i --input Input image or folder. Default: inputs
|
|
-o --output Output folder. Default: results
|
|
-n --model_name Model name. Default: RealESRGAN_x4plus
|
|
-s, --outscale The final upsampling scale of the image. Default: 4
|
|
--suffix Suffix of the restored image. Default: out
|
|
-t, --tile Tile size, 0 for no tile during testing. Default: 0
|
|
--face_enhance Whether to use GFPGAN to enhance face. Default: False
|
|
--fp32 Whether to use half precision during inference. Default: False
|
|
--ext Image extension. Options: auto | jpg | png, auto means using the same extension as inputs. Default: auto
|
|
```
