|
| 2 |
+
|
| 3 |
+
## Our Pledge
|
| 4 |
+
|
| 5 |
+
We as members, contributors, and leaders pledge to make participation in our
|
| 6 |
+
community a harassment-free experience for everyone, regardless of age, body
|
| 7 |
+
size, visible or invisible disability, ethnicity, sex characteristics, gender
|
| 8 |
+
identity and expression, level of experience, education, socio-economic status,
|
| 9 |
+
nationality, personal appearance, race, religion, or sexual identity
|
| 10 |
+
and orientation.
|
| 11 |
+
|
| 12 |
+
We pledge to act and interact in ways that contribute to an open, welcoming,
|
| 13 |
+
diverse, inclusive, and healthy community.
|
| 14 |
+
|
| 15 |
+
## Our Standards
|
| 16 |
+
|
| 17 |
+
Examples of behavior that contributes to a positive environment for our
|
| 18 |
+
community include:
|
| 19 |
+
|
| 20 |
+
* Demonstrating empathy and kindness toward other people
|
| 21 |
+
* Being respectful of differing opinions, viewpoints, and experiences
|
| 22 |
+
* Giving and gracefully accepting constructive feedback
|
| 23 |
+
* Accepting responsibility and apologizing to those affected by our mistakes,
|
| 24 |
+
and learning from the experience
|
| 25 |
+
* Focusing on what is best not just for us as individuals, but for the
|
| 26 |
+
overall community
|
| 27 |
+
|
| 28 |
+
Examples of unacceptable behavior include:
|
| 29 |
+
|
| 30 |
+
* The use of sexualized language or imagery, and sexual attention or
|
| 31 |
+
advances of any kind
|
| 32 |
+
* Trolling, insulting or derogatory comments, and personal or political attacks
|
| 33 |
+
* Public or private harassment
|
| 34 |
+
* Publishing others' private information, such as a physical or email
|
| 35 |
+
address, without their explicit permission
|
| 36 |
+
* Other conduct which could reasonably be considered inappropriate in a
|
| 37 |
+
professional setting
|
| 38 |
+
|
| 39 |
+
## Enforcement Responsibilities
|
| 40 |
+
|
| 41 |
+
Community leaders are responsible for clarifying and enforcing our standards of
|
| 42 |
+
acceptable behavior and will take appropriate and fair corrective action in
|
| 43 |
+
response to any behavior that they deem inappropriate, threatening, offensive,
|
| 44 |
+
or harmful.
|
| 45 |
+
|
| 46 |
+
Community leaders have the right and responsibility to remove, edit, or reject
|
| 47 |
+
comments, commits, code, wiki edits, issues, and other contributions that are
|
| 48 |
+
not aligned to this Code of Conduct, and will communicate reasons for moderation
|
| 49 |
+
decisions when appropriate.
|
| 50 |
+
|
| 51 |
+
## Scope
|
| 52 |
+
|
| 53 |
+
This Code of Conduct applies within all community spaces, and also applies when
|
| 54 |
+
an individual is officially representing the community in public spaces.
|
| 55 |
+
Examples of representing our community include using an official e-mail address,
|
| 56 |
+
posting via an official social media account, or acting as an appointed
|
| 57 |
+
representative at an online or offline event.
|
| 58 |
+
|
| 59 |
+
## Enforcement
|
| 60 |
+
|
| 61 |
+
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
| 62 |
+
reported to the community leaders responsible for enforcement at
|
| 63 |
+
xintao.wang@outlook.com or xintaowang@tencent.com.
|
| 64 |
+
All complaints will be reviewed and investigated promptly and fairly.
|
| 65 |
+
|
| 66 |
+
All community leaders are obligated to respect the privacy and security of the
|
| 67 |
+
reporter of any incident.
|
| 68 |
+
|
| 69 |
+
## Enforcement Guidelines
|
| 70 |
+
|
| 71 |
+
Community leaders will follow these Community Impact Guidelines in determining
|
| 72 |
+
the consequences for any action they deem in violation of this Code of Conduct:
|
| 73 |
+
|
| 74 |
+
### 1. Correction
|
| 75 |
+
|
| 76 |
+
**Community Impact**: Use of inappropriate language or other behavior deemed
|
| 77 |
+
unprofessional or unwelcome in the community.
|
| 78 |
+
|
| 79 |
+
**Consequence**: A private, written warning from community leaders, providing
|
| 80 |
+
clarity around the nature of the violation and an explanation of why the
|
| 81 |
+
behavior was inappropriate. A public apology may be requested.
|
| 82 |
+
|
| 83 |
+
### 2. Warning
|
| 84 |
+
|
| 85 |
+
**Community Impact**: A violation through a single incident or series
|
| 86 |
+
of actions.
|
| 87 |
+
|
| 88 |
+
**Consequence**: A warning with consequences for continued behavior. No
|
| 89 |
+
interaction with the people involved, including unsolicited interaction with
|
| 90 |
+
those enforcing the Code of Conduct, for a specified period of time. This
|
| 91 |
+
includes avoiding interactions in community spaces as well as external channels
|
| 92 |
+
like social media. Violating these terms may lead to a temporary or
|
| 93 |
+
permanent ban.
|
| 94 |
+
|
| 95 |
+
### 3. Temporary Ban
|
| 96 |
+
|
| 97 |
+
**Community Impact**: A serious violation of community standards, including
|
| 98 |
+
sustained inappropriate behavior.
|
| 99 |
+
|
| 100 |
+
**Consequence**: A temporary ban from any sort of interaction or public
|
| 101 |
+
communication with the community for a specified period of time. No public or
|
| 102 |
+
private interaction with the people involved, including unsolicited interaction
|
| 103 |
+
with those enforcing the Code of Conduct, is allowed during this period.
|
| 104 |
+
Violating these terms may lead to a permanent ban.
|
| 105 |
+
|
| 106 |
+
### 4. Permanent Ban
|
| 107 |
+
|
| 108 |
+
**Community Impact**: Demonstrating a pattern of violation of community
|
| 109 |
+
standards, including sustained inappropriate behavior, harassment of an
|
| 110 |
+
individual, or aggression toward or disparagement of classes of individuals.
|
| 111 |
+
|
| 112 |
+
**Consequence**: A permanent ban from any sort of public interaction within
|
| 113 |
+
the community.

<!---------------------------------- Updates --------------------------->
|
| 60 |
+
## 🚩 Updates
|
| 61 |
+
|
| 62 |
+
- ✅ Add the **realesr-general-x4v3** model - a tiny small model for general scenes. It also supports the **-dn** option to balance the noise (avoiding over-smooth results). **-dn** is short for denoising strength.
|
| 63 |
+
- ✅ Update the **RealESRGAN AnimeVideo-v3** model. Please see [anime video models](docs/anime_video_model.md) and [comparisons](docs/anime_comparisons.md) for more details.
|
| 64 |
+
- ✅ Add small models for anime videos. More details are in [anime video models](docs/anime_video_model.md).
|
| 65 |
+
- ✅ Add the ncnn implementation [Real-ESRGAN-ncnn-vulkan](https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan).
|
| 66 |
+
- ✅ Add [*RealESRGAN_x4plus_anime_6B.pth*](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.4/RealESRGAN_x4plus_anime_6B.pth), which is optimized for **anime** images with much smaller model size. More details and comparisons with [waifu2x](https://github.com/nihui/waifu2x-ncnn-vulkan) are in [**anime_model.md**](docs/anime_model.md)
|
| 67 |
+
- ✅ Support finetuning on your own data or paired data (*i.e.*, finetuning ESRGAN). See [here](docs/Training.md#Finetune-Real-ESRGAN-on-your-own-dataset)
|
| 68 |
+
- ✅ Integrate [GFPGAN](https://github.com/TencentARC/GFPGAN) to support **face enhancement**.
|
| 69 |
+
- ✅ Integrated to [Huggingface Spaces](https://huggingface.co/spaces) with [Gradio](https://github.com/gradio-app/gradio). See [Gradio Web Demo](https://huggingface.co/spaces/akhaliq/Real-ESRGAN). Thanks [@AK391](https://github.com/AK391)
|
| 70 |
+
- ✅ Support arbitrary scale with `--outscale` (It actually further resizes outputs with `LANCZOS4`). Add *RealESRGAN_x2plus.pth* model.
|
| 71 |
+
- ✅ [The inference code](inference_realesrgan.py) supports: 1) **tile** options; 2) images with **alpha channel**; 3) **gray** images; 4) **16-bit** images.
|
| 72 |
+
- ✅ The training codes have been released. A detailed guide can be found in [Training.md](docs/Training.md).

## ⚡ Quick Inference
|
| 117 |
+
|
| 118 |
+
There are usually three ways to inference Real-ESRGAN.
|
| 119 |
+
|
| 120 |
+
1. [Online inference](#online-inference)
|
| 121 |
+
1. [Portable executable files (NCNN)](#portable-executable-files-ncnn)
|
| 122 |
+
1. [Python script](#python-script)
|
| 123 |
+
|
| 124 |
+
### Online inference
|
| 125 |
+
|
| 126 |
+
1. You can try in our website: [ARC Demo](https://arc.tencent.com/en/ai-demos/imgRestore) (now only support RealESRGAN_x4plus_anime_6B)
|
| 127 |
+
1. [Colab Demo](https://colab.research.google.com/drive/1k2Zod6kSHEvraybHl50Lys0LerhyTMCo?usp=sharing) for Real-ESRGAN **|** [Colab Demo](https://colab.research.google.com/drive/1yNl9ORUxxlL4N0keJa2SEPB61imPQd1B?usp=sharing) for Real-ESRGAN (**anime videos**).
|
| 128 |
+
|
| 129 |
+
### Portable executable files (NCNN)
|
| 130 |
+
|
| 131 |
+
You can download [Windows](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-windows.zip) / [Linux](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-ubuntu.zip) / [MacOS](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-macos.zip) **executable files for Intel/AMD/Nvidia GPU**.
|
| 132 |
+
|
| 133 |
+
This executable file is **portable** and includes all the binaries and models required. No CUDA or PyTorch environment is needed.<br>
|
| 134 |
+
|
| 135 |
+
You can simply run the following command (the Windows example, more information is in the README.md of each executable files):
|
| 136 |
+
|
| 137 |
+
```bash
|
| 138 |
+
./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n model_name
|
| 139 |
+
```
|
| 140 |
+
|
| 141 |
+
We have provided five models:
|
| 142 |
+
|
| 143 |
+
1. realesrgan-x4plus (default)
|
| 144 |
+
2. realesrnet-x4plus
|
| 145 |
+
3. realesrgan-x4plus-anime (optimized for anime images, small model size)
|
| 146 |
+
4. realesr-animevideov3 (animation video)
|
| 147 |
+
|
| 148 |
+
You can use the `-n` argument for other models, for example, `./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n realesrnet-x4plus`
|
| 149 |
+
|
| 150 |
+
#### Usage of portable executable files
|
| 151 |
+
|
| 152 |
+
1. Please refer to [Real-ESRGAN-ncnn-vulkan](https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan#computer-usages) for more details.
|
| 153 |
+
1. Note that it does not support all the functions (such as `outscale`) as the python script `inference_realesrgan.py`.
|
| 154 |
+
|
| 155 |
+
```console
|
| 156 |
+
Usage: realesrgan-ncnn-vulkan.exe -i infile -o outfile [options]...
|
| 157 |
+
|
| 158 |
+
-h show this help
|
| 159 |
+
-i input-path input image path (jpg/png/webp) or directory
|
| 160 |
+
-o output-path output image path (jpg/png/webp) or directory
|
| 161 |
+
-s scale upscale ratio (can be 2, 3, 4. default=4)
|
| 162 |
+
-t tile-size tile size (>=32/0=auto, default=0) can be 0,0,0 for multi-gpu
|
| 163 |
+
-m model-path folder path to the pre-trained models. default=models
|
| 164 |
+
-n model-name model name (default=realesr-animevideov3, can be realesr-animevideov3 | realesrgan-x4plus | realesrgan-x4plus-anime | realesrnet-x4plus)
|
| 165 |
+
-g gpu-id gpu device to use (default=auto) can be 0,1,2 for multi-gpu
|
| 166 |
+
-j load:proc:save thread count for load/proc/save (default=1:2:2) can be 1:2,2,2:2 for multi-gpu
|
| 167 |
+
-x enable tta mode"
|
| 168 |
+
-f format output image format (jpg/png/webp, default=ext/png)
|
| 169 |
+
-v verbose output
|
| 170 |
+
```
|
| 171 |
+
|
| 172 |
+
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.
|
| 173 |
+
|
| 174 |
+
### Python script
|
| 175 |
+
|
| 176 |
+
#### Usage of python script
|
| 177 |
+
|
| 178 |
+
1. You can use X4 model for **arbitrary output size** with the argument `outscale`. The program will further perform cheap resize operation after the Real-ESRGAN output.
|
| 179 |
+
|
| 180 |
+
```console
|
| 181 |
+
Usage: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile -o outfile [options]...
|
| 182 |
+
|
| 183 |
+
A common command: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile --outscale 3.5 --face_enhance
|
| 184 |
+
|
| 185 |
+
-h show this help
|
| 186 |
+
-i --input Input image or folder. Default: inputs
|
| 187 |
+
-o --output Output folder. Default: results
|
| 188 |
+
-n --model_name Model name. Default: RealESRGAN_x4plus
|
| 189 |
+
-s, --outscale The final upsampling scale of the image. Default: 4
|
| 190 |
+
--suffix Suffix of the restored image. Default: out
|
| 191 |
+
-t, --tile Tile size, 0 for no tile during testing. Default: 0
|
| 192 |
+
--face_enhance Whether to use GFPGAN to enhance face. Default: False
|
| 193 |
+
--fp32 Use fp32 precision during inference. Default: fp16 (half precision).
|
| 194 |
+
--ext Image extension. Options: auto | jpg | png, auto means using the same extension as inputs. Default: auto
|
| 195 |
+
```
|
| 196 |
+
|
| 197 |
+
#### Inference general images
|
| 198 |
+
|
| 199 |

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>
|
| 99 |
+
**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>
|
| 100 |
+
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>
|
| 101 |
+
|
| 102 |
+
Real-ESRGAN 将会被长期支持，我会在空闲的时间中持续维护更新。
|
| 103 |
+
|
| 104 |
+
这些是未来计划的几个新功能：
|
| 105 |
+
|
| 106 |
+
- [ ] 优化人脸
|
| 107 |
+
- [ ] 优化文字
|
| 108 |
+
- [x] 优化动画图像
|
| 109 |
+
- [ ] 支持更多的超分辨率比例
|
| 110 |
+
- [ ] 可调节的复原
|
| 111 |
+
|
| 112 |
+
如果你有好主意或需求，欢迎在 issue 或 discussion 中提出。<br/>
|
| 113 |
+
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
|
| 118 |
+
|
| 119 |
+
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)。
|
| 120 |
+
|
| 121 |
+
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>
|
| 122 |
+
|
| 123 |
+
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）：
|
| 124 |
+
|
| 125 |
+
```bash
|
| 126 |
+
./realesrgan-ncnn-vulkan.exe -i 输入图像.jpg -o 输出图像.png -n 模型名字
|
| 127 |
+
```
|
| 128 |
+
|
| 129 |
+
我们提供了五种模型：
|
| 130 |
+
|
| 131 |
+
1. realesrgan-x4plus（默认）
|
| 132 |
+
2. reaesrnet-x4plus
|
| 133 |
+
3. realesrgan-x4plus-anime（针对动漫插画图像优化，有更小的体积）
|
| 134 |
+
4. realesr-animevideov3 (针对动漫视频)
|
| 135 |
+
|
| 136 |
+
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`
|
| 137 |
+
|
| 138 |
+
### 可执行文件的用法
|
| 139 |
+
|
| 140 |
+
1. 更多细节可以参考 [Real-ESRGAN-ncnn-vulkan](https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan#computer-usages).
|
| 141 |
+
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) .
|
| 142 |
+
|
| 143 |
+
```console
|
| 144 |
+
Usage: realesrgan-ncnn-vulkan.exe -i infile -o outfile [options]...
|
| 145 |
+
|
| 146 |
+
-h show this help
|
| 147 |
+
-i input-path input image path (jpg/png/webp) or directory
|
| 148 |
+
-o output-path output image path (jpg/png/webp) or directory
|
| 149 |
+
-s scale upscale ratio (can be 2, 3, 4. default=4)
|
| 150 |
+
-t tile-size tile size (>=32/0=auto, default=0) can be 0,0,0 for multi-gpu
|
| 151 |
+
-m model-path folder path to the pre-trained models. default=models
|
| 152 |
+
-n model-name model name (default=realesr-animevideov3, can be realesr-animevideov3 | realesrgan-x4plus | realesrgan-x4plus-anime | realesrnet-x4plus)
|
| 153 |
+
-g gpu-id gpu device to use (default=auto) can be 0,1,2 for multi-gpu
|
| 154 |
+
-j load:proc:save thread count for load/proc/save (default=1:2:2) can be 1:2,2,2:2 for multi-gpu
|
| 155 |
+
-x enable tta mode"
|
| 156 |
+
-f format output image format (jpg/png/webp, default=ext/png)
|
| 157 |
+
-v verbose output
|
| 158 |
+
```
|
| 159 |
+
|
| 160 |
+
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）

### Python 脚本的用法
|
| 228 |
+
|
| 229 |
+
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。
|
| 230 |
+
|
| 231 |
+
```console
|
| 232 |
+
Usage: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile -o outfile [options]...
|
| 233 |
+
|
| 234 |
+
A common command: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile --outscale 3.5 --face_enhance
|
| 235 |
+
|
| 236 |
+
-h show this help
|
| 237 |
+
-i --input Input image or folder. Default: inputs
|
| 238 |
+
-o --output Output folder. Default: results
|
| 239 |
+
-n --model_name Model name. Default: RealESRGAN_x4plus
|
| 240 |
+
-s, --outscale The final upsampling scale of the image. Default: 4
|
| 241 |
+
--suffix Suffix of the restored image. Default: out
|
| 242 |
+
-t, --tile Tile size, 0 for no tile during testing. Default: 0
|
| 243 |
+
--face_enhance Whether to use GFPGAN to enhance face. Default: False
|
| 244 |
+
--fp32 Whether to use half precision during inference. Default: False
|
| 245 |
+
--ext Image extension. Options: auto | jpg | png, auto means using the same extension as inputs. Default: auto
|
| 246 |
+
```

# Contributing to Real-ESRGAN
|
| 2 |
+
|
| 3 |
+
:art: Real-ESRGAN needs your contributions. Any contributions are welcome, such as new features/models/typo fixes/suggestions/maintenance, *etc*. See [CONTRIBUTING.md](docs/CONTRIBUTING.md). All contributors are list [here](README.md#hugs-acknowledgement).
|
| 4 |
+
|
| 5 |
+
We like open-source and want to develop practical algorithms for general image restoration. However, individual strength is limited. So, any kinds of contributions are welcome, such as:
|
| 6 |
+
|
| 7 |
+
- New features
|
| 8 |
+
- New models (your fine-tuned models)
|
| 9 |
+
- Bug fixes
|
| 10 |
+
- Typo fixes
|
| 11 |
+
- Suggestions
|
| 12 |
+
- Maintenance
|
| 13 |
+
- Documents
|
| 14 |
+
- *etc*
|
| 15 |
+
|
| 16 |
+
## Workflow
|
| 17 |
+
|
| 18 |
+
1. Fork and pull the latest Real-ESRGAN repository
|
| 19 |
+
1. Checkout a new branch (do not use master branch for PRs)
|
| 20 |
+
1. Commit your changes
|
| 21 |
+
1. Create a PR
|
| 22 |
+
|
| 23 |
+
**Note**:
|
| 24 |
+
|
| 25 |
+
1. Please check the code style and linting
|
| 26 |
+
1. The style configuration is specified in [setup.cfg](setup.cfg)
|
| 27 |
+
1. If you use VSCode, the settings are configured in [.vscode/settings.json](.vscode/settings.json)
|
| 28 |
+
1. Strongly recommend using `pre-commit hook`. It will check your code style and linting before your commit.
|
| 29 |
+
1. In the root path of project folder, run `pre-commit install`
|
| 30 |
+
1. The pre-commit configuration is listed in [.pre-commit-config.yaml](.pre-commit-config.yaml)
|
| 31 |
+
1. Better to [open a discussion](https://github.com/xinntao/Real-ESRGAN/discussions) before large changes.
|
| 32 |
+
1. Welcome to discuss :sunglasses:. I will try my best to join the discussion.
|
| 33 |
+
|
| 34 |
+
## TODO List
|
| 35 |
+
|
| 36 |
+
:zero: The most straightforward way of improving model performance is to fine-tune on some specific datasets.
|
| 37 |
+
|
| 38 |
+
Here are some TODOs:
|
| 39 |
+
|
| 40 |
+
- [ ] optimize for human faces
|
| 41 |
+
- [ ] optimize for texts
|
| 42 |
+
- [ ] support controllable restoration strength
|
| 43 |
+
|
| 44 |
+
:one: There are also [several issues](https://github.com/xinntao/Real-ESRGAN/issues) that require helpers to improve. If you can help, please let me know :smile:

# FAQ
|
| 2 |
+
|
| 3 |
+
1. **Q: How to select models?**<br>
|
| 4 |
+
A: Please refer to [docs/model_zoo.md](docs/model_zoo.md)
|
| 5 |
+
|
| 6 |
+
1. **Q: Can `face_enhance` be used for anime images/animation videos?**<br>
|
| 7 |
+
A: No, it can only be used for real faces. It is recommended not to use this option for anime images/animation videos to save GPU memory.
|
| 8 |
+
|
| 9 |
+
1. **Q: Error "slow_conv2d_cpu" not implemented for 'Half'**<br>
|
| 10 |
+
A: In order to save GPU memory consumption and speed up inference, Real-ESRGAN uses half precision (fp16) during inference by default. However, some operators for half inference are not implemented in CPU mode. You need to add **`--fp32` option** for the commands. For example, `python inference_realesrgan.py -n RealESRGAN_x4plus.pth -i inputs --fp32`.

The training has been divided into two stages. These two stages have the same data synthesis process and training pipeline, except for the loss functions. Specifically,

|
| 10 |
1. We first train Real-ESRNet with L1 loss from the pre-trained model ESRGAN.
|
| 11 |
1. We then use the trained Real-ESRNet model as an initialization of the generator, and train the Real-ESRGAN with a combination of L1 loss, perceptual loss and GAN loss.

## Train Real-ESRGAN
|
| 15 |
+
|
| 16 |
+
### Overview
|
| 17 |
|
| 18 |
The training has been divided into two stages. These two stages have the same data synthesis process and training pipeline, except for the loss functions. Specifically,
|
| 19 |
|
| 20 |
1. We first train Real-ESRNet with L1 loss from the pre-trained model ESRGAN.
|
| 21 |
1. We then use the trained Real-ESRNet model as an initialization of the generator, and train the Real-ESRGAN with a combination of L1 loss, perceptual loss and GAN loss.
|
| 22 |
|
| 23 |
+
### Dataset Preparation
|
| 24 |
|
| 25 |
We use DF2K (DIV2K and Flickr2K) + OST datasets for our training. Only HR images are required. <br>
|
| 26 |
You can download from :
|
|
|
|
| 29 |
2. Flickr2K: https://cv.snu.ac.kr/research/EDSR/Flickr2K.tar
|
| 30 |
3. OST: https://openmmlab.oss-cn-hangzhou.aliyuncs.com/datasets/OST_dataset.zip
|
| 31 |
|
| 32 |
+
Here are steps for data preparation.
|
| 33 |
+
|
| 34 |
+
#### Step 1: [Optional] Generate multi-scale images
|
| 35 |
+
|
| 36 |
+
For the DF2K dataset, we use a multi-scale strategy, *i.e.*, we downsample HR images to obtain several Ground-Truth images with different scales. <br>
|
| 37 |
+
You can use the [scripts/generate_multiscale_DF2K.py](scripts/generate_multiscale_DF2K.py) script to generate multi-scale images. <br>
|
| 38 |
+
Note that this step can be omitted if you just want to have a fast try.
|
| 39 |
+
|
| 40 |
+
```bash
|
| 41 |
+
python scripts/generate_multiscale_DF2K.py --input datasets/DF2K/DF2K_HR --output datasets/DF2K/DF2K_multiscale
|
| 42 |
+
```
|
| 43 |
+
|
| 44 |
+
#### Step 2: [Optional] Crop to sub-images
|
| 45 |
+
|
| 46 |
+
We then crop DF2K images into sub-images for faster IO and processing.<br>
|
| 47 |
+
This step is optional if your IO is enough or your disk space is limited.
|
| 48 |
+
|
| 49 |
+
You can use the [scripts/extract_subimages.py](scripts/extract_subimages.py) script. Here is the example:
|
| 50 |
|
| 51 |
+
```bash
|
| 52 |
+
python scripts/extract_subimages.py --input datasets/DF2K/DF2K_multiscale --output datasets/DF2K/DF2K_multiscale_sub --crop_size 400 --step 200
|
| 53 |
+
```
|
| 54 |
+
|
| 55 |
+
#### Step 3: Prepare a txt for meta information
|
| 56 |
|
| 57 |
You need to prepare a txt file containing the image paths. The following are some examples in `meta_info_DF2Kmultiscale+OST_sub.txt` (As different users may have different sub-images partitions, this file is not suitable for your purpose and you need to prepare your own txt file):
|
| 58 |
|
|
|
|
| 63 |
...
|
| 64 |
```
|
| 65 |
|
| 66 |
+
You can use the [scripts/generate_meta_info.py](scripts/generate_meta_info.py) script to generate the txt file. <br>
|
| 67 |
+
You can merge several folders into one meta_info txt. Here is the example:
|
| 68 |
+
|
| 69 |
+
```bash
|
| 70 |
+
python scripts/generate_meta_info.py --input datasets/DF2K/DF2K_HR datasets/DF2K/DF2K_multiscale --root datasets/DF2K datasets/DF2K --meta_info datasets/DF2K/meta_info/meta_info_DF2Kmultiscale.txt
|
| 71 |
+
```
|
| 72 |
+
|
| 73 |
+
### Train Real-ESRNet
|
| 74 |
|
| 75 |
1. Download pre-trained model [ESRGAN](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.1/ESRGAN_SRx4_DF2KOST_official-ff704c30.pth) into `experiments/pretrained_models`.
|
| 76 |
```bash
|
|
|
|
| 116 |
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 117 |
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --launcher pytorch --debug
|
| 118 |
```
|
| 119 |
+
|
| 120 |
+
Train with **a single GPU** in the *debug* mode:
|
| 121 |
+
```bash
|
| 122 |
+
python realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --debug
|
| 123 |
+
```
|
| 124 |
1. The formal training. We use four GPUs for training. We use the `--auto_resume` argument to automatically resume the training if necessary.
|
| 125 |
```bash
|
| 126 |
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 127 |
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --launcher pytorch --auto_resume
|
| 128 |
```
|
| 129 |
|
| 130 |
+
Train with **a single GPU**:
|
| 131 |
+
```bash
|
| 132 |
+
python realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --auto_resume
|
| 133 |
+
```
|
| 134 |
+
|
| 135 |
+
### Train Real-ESRGAN
|
| 136 |
|
| 137 |
1. After the training of Real-ESRNet, you now have the file `experiments/train_RealESRNetx4plus_1000k_B12G4_fromESRGAN/model/net_g_1000000.pth`. If you need to specify the pre-trained path to other files, modify the `pretrain_network_g` value in the option file `train_realesrgan_x4plus.yml`.
|
| 138 |
1. Modify the option file `train_realesrgan_x4plus.yml` accordingly. Most modifications are similar to those listed above.
|
|
|
|
| 141 |
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 142 |
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --launcher pytorch --debug
|
| 143 |
```
|
| 144 |
+
|
| 145 |
+
Train with **a single GPU** in the *debug* mode:
|
| 146 |
+
```bash
|
| 147 |
+
python realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --debug
|
| 148 |
+
```
|
| 149 |
1. The formal training. We use four GPUs for training. We use the `--auto_resume` argument to automatically resume the training if necessary.
|
| 150 |
```bash
|
| 151 |
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 152 |
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --launcher pytorch --auto_resume
|
| 153 |
```
|
| 154 |
+
|
| 155 |
+
Train with **a single GPU**:
|
| 156 |
+
```bash
|
| 157 |
+
python realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --auto_resume
|
| 158 |
+
```
|
| 159 |
+
|
| 160 |
+
## Finetune Real-ESRGAN on your own dataset
|
| 161 |
+
|
| 162 |
+
You can finetune Real-ESRGAN on your own dataset. Typically, the fine-tuning process can be divided into two cases:
|
| 163 |
+
|
| 164 |
+
1. [Generate degraded images on the fly](#Generate-degraded-images-on-the-fly)
|
| 165 |
+
1. [Use your own **paired** data](#Use-paired-training-data)
|
| 166 |
+
|
| 167 |
+
### Generate degraded images on the fly
|
| 168 |
+
|
| 169 |
+
Only high-resolution images are required. The low-quality images are generated with the degradation process described in Real-ESRGAN during training.
|
| 170 |
+
|
| 171 |
+
**1. Prepare dataset**
|
| 172 |
+
|
| 173 |
+
See [this section](#dataset-preparation) for more details.
|
| 174 |
+
|
| 175 |
+
**2. Download pre-trained models**
|
| 176 |
+
|
| 177 |
+
Download pre-trained models into `experiments/pretrained_models`.
|
| 178 |
+
|
| 179 |
+
- *RealESRGAN_x4plus.pth*:
|
| 180 |
+
```bash
|
| 181 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.0/RealESRGAN_x4plus.pth -P experiments/pretrained_models
|
| 182 |
+
```
|
| 183 |
+
|
| 184 |
+
- *RealESRGAN_x4plus_netD.pth*:
|
| 185 |
+
```bash
|
| 186 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.3/RealESRGAN_x4plus_netD.pth -P experiments/pretrained_models
|
| 187 |
+
```
|
| 188 |
+
|
| 189 |
+
**3. Finetune**
|
| 190 |
+
|
| 191 |
+
Modify [options/finetune_realesrgan_x4plus.yml](options/finetune_realesrgan_x4plus.yml) accordingly, especially the `datasets` part:
|
| 192 |
+
|
| 193 |
+
```yml
|
| 194 |
+
train:
|
| 195 |
+
name: DF2K+OST
|
| 196 |
+
type: RealESRGANDataset
|
| 197 |
+
dataroot_gt: datasets/DF2K # modify to the root path of your folder
|
| 198 |
+
meta_info: realesrgan/meta_info/meta_info_DF2Kmultiscale+OST_sub.txt # modify to your own generate meta info txt
|
| 199 |
+
io_backend:
|
| 200 |
+
type: disk
|
| 201 |
+
```
|
| 202 |
+
|
| 203 |
+
We use four GPUs for training. We use the `--auto_resume` argument to automatically resume the training if necessary.
|
| 204 |
+
|
| 205 |
+
```bash
|
| 206 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 207 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/finetune_realesrgan_x4plus.yml --launcher pytorch --auto_resume
|
| 208 |
+
```
|
| 209 |
+
|
| 210 |
+
Finetune with **a single GPU**:
|
| 211 |
+
```bash
|
| 212 |
+
python realesrgan/train.py -opt options/finetune_realesrgan_x4plus.yml --auto_resume
|
| 213 |
+
```
|
| 214 |
+
|
| 215 |
+
### Use your own paired data
|
| 216 |
+
|
| 217 |
+
You can also finetune RealESRGAN with your own paired data. It is more similar to fine-tuning ESRGAN.
|
| 218 |
+
|
| 219 |
+
**1. Prepare dataset**
|
| 220 |
+
|
| 221 |
+
Assume that you already have two folders:
|
| 222 |
+
|
| 223 |
+
- **gt folder** (Ground-truth, high-resolution images): *datasets/DF2K/DIV2K_train_HR_sub*
|
| 224 |
+
- **lq folder** (Low quality, low-resolution images): *datasets/DF2K/DIV2K_train_LR_bicubic_X4_sub*
|
| 225 |
+
|
| 226 |
+
Then, you can prepare the meta_info txt file using the script [scripts/generate_meta_info_pairdata.py](scripts/generate_meta_info_pairdata.py):
|
| 227 |
+
|
| 228 |
+
```bash
|
| 229 |
+
python scripts/generate_meta_info_pairdata.py --input datasets/DF2K/DIV2K_train_HR_sub datasets/DF2K/DIV2K_train_LR_bicubic_X4_sub --meta_info datasets/DF2K/meta_info/meta_info_DIV2K_sub_pair.txt
|
| 230 |
+
```
|
| 231 |
+
|
| 232 |
+
**2. Download pre-trained models**
|
| 233 |
+
|
| 234 |
+
Download pre-trained models into `experiments/pretrained_models`.
|
| 235 |
+
|
| 236 |
+
- *RealESRGAN_x4plus.pth*
|
| 237 |
+
```bash
|
| 238 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.0/RealESRGAN_x4plus.pth -P experiments/pretrained_models
|
| 239 |
+
```
|
| 240 |
+
|
| 241 |
+
- *RealESRGAN_x4plus_netD.pth*
|
| 242 |
+
```bash
|
| 243 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.3/RealESRGAN_x4plus_netD.pth -P experiments/pretrained_models
|
| 244 |
+
```
|
| 245 |
+
|
| 246 |
+
**3. Finetune**
|
| 247 |
+
|
| 248 |
+
Modify [options/finetune_realesrgan_x4plus_pairdata.yml](options/finetune_realesrgan_x4plus_pairdata.yml) accordingly, especially the `datasets` part:
|
| 249 |
+
|
| 250 |
+
```yml
|
| 251 |
+
train:
|
| 252 |
+
name: DIV2K
|
| 253 |
+
type: RealESRGANPairedDataset
|
| 254 |
+
dataroot_gt: datasets/DF2K # modify to the root path of your folder
|
| 255 |
+
dataroot_lq: datasets/DF2K # modify to the root path of your folder
|
| 256 |
+
meta_info: datasets/DF2K/meta_info/meta_info_DIV2K_sub_pair.txt # modify to your own generate meta info txt
|
| 257 |
+
io_backend:
|
| 258 |
+
type: disk
|
| 259 |
+
```
|
| 260 |
+
|
| 261 |
+
We use four GPUs for training. We use the `--auto_resume` argument to automatically resume the training if necessary.
|
| 262 |
+
|
| 263 |
+
```bash
|
| 264 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 265 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/finetune_realesrgan_x4plus_pairdata.yml --launcher pytorch --auto_resume
|
| 266 |
+
```
|
| 267 |
+
|
| 268 |
+
Finetune with **a single GPU**:
|
| 269 |
+
```bash
|
| 270 |
+
python realesrgan/train.py -opt options/finetune_realesrgan_x4plus_pairdata.yml --auto_resume
|
| 271 |
+
```

## 训练 Real-ESRGAN
|
| 15 |
+
|
| 16 |
+
### 概述
|
| 17 |
+
|
| 18 |
+
训练分为两个步骤。除了 loss 函数外，这两个步骤拥有相同数据合成以及训练的一条龙流程。具体点说：
|
| 19 |
+
|
| 20 |
+
1. 首先使用 L1 loss 训练 Real-ESRNet 模型，其中 L1 loss 来自预先训练的 ESRGAN 模型。
|
| 21 |
+
|
| 22 |
+
2. 然后我们将 Real-ESRNet 模型作为生成器初始化，结合L1 loss、感知 loss、GAN loss 三者的参数对 Real-ESRGAN 进行训练。
|
| 23 |
+
|
| 24 |
+
### 准备数据集
|
| 25 |
+
|
| 26 |
+
我们使用 DF2K ( DIV2K 和 Flickr2K ) + OST 数据集进行训练。只需要HR图像！<br>
|
| 27 |
+
下面是网站链接:
|
| 28 |
+
1. DIV2K: http://data.vision.ee.ethz.ch/cvl/DIV2K/DIV2K_train_HR.zip
|
| 29 |
+
2. Flickr2K: https://cv.snu.ac.kr/research/EDSR/Flickr2K.tar
|
| 30 |
+
3. OST: https://openmmlab.oss-cn-hangzhou.aliyuncs.com/datasets/OST_dataset.zip
|
| 31 |
+
|
| 32 |
+
以下是数据的准备步骤。
|
| 33 |
+
|
| 34 |
+
#### 第1步：【可选】生成多尺寸图片
|
| 35 |
+
|
| 36 |
+
针对 DF2K 数据集，我们使用多尺寸缩放策略，*换言之*，我们对 HR 图像进行下采样，就能获得多尺寸的标准参考（Ground-Truth）图像。 <br>
|
| 37 |
+
您可以使用这个 [scripts/generate_multiscale_DF2K.py](scripts/generate_multiscale_DF2K.py) 脚本快速生成多尺寸的图像。<br>
|
| 38 |
+
注意：如果您只想简单试试，那么可以跳过此步骤。
|
| 39 |
+
|
| 40 |
+
```bash
|
| 41 |
+
python scripts/generate_multiscale_DF2K.py --input datasets/DF2K/DF2K_HR --output datasets/DF2K/DF2K_multiscale
|
| 42 |
+
```
|
| 43 |
+
|
| 44 |
+
#### 第2步：【可选】裁切为子图像
|
| 45 |
+
|
| 46 |
+
我们可以将 DF2K 图像裁切为子图像，以加快 IO 和处理速度。<br>
|
| 47 |
+
如果你的 IO 够好或储存空间有限，那么此步骤是可选的。<br>
|
| 48 |
+
|
| 49 |
+
您可以使用脚本 [scripts/extract_subimages.py](scripts/extract_subimages.py)。这是使用示例:
|
| 50 |
+
|
| 51 |
+
```bash
|
| 52 |
+
python scripts/extract_subimages.py --input datasets/DF2K/DF2K_multiscale --output datasets/DF2K/DF2K_multiscale_sub --crop_size 400 --step 200
|
| 53 |
+
```
|
| 54 |
+
|
| 55 |
+
#### 第3步：准备元信息 txt
|
| 56 |
+
|
| 57 |
+
您需要准备一个包含图像路径的 txt 文件。下面是 `meta_info_DF2Kmultiscale+OST_sub.txt` 中的部分展示（由于各个用户可能有截然不同的子图像划分，这个文件不适合你的需求，你得准备自己的 txt 文件)：
|
| 58 |
+
|
| 59 |
+
```txt
|
| 60 |
+
DF2K_HR_sub/000001_s001.png
|
| 61 |
+
DF2K_HR_sub/000001_s002.png
|
| 62 |
+
DF2K_HR_sub/000001_s003.png
|
| 63 |
+
...
|
| 64 |
+
```
|
| 65 |
+
|
| 66 |
+
你可以使用该脚本 [scripts/generate_meta_info.py](scripts/generate_meta_info.py) 生成包含图像路径的 txt 文件。<br>
|
| 67 |
+
你还可以合并多个文件夹的图像路径到一个元信息（meta_info）txt。这是使用示例:
|
| 68 |
+
|
| 69 |
+
```bash
|
| 70 |
+
python scripts/generate_meta_info.py --input datasets/DF2K/DF2K_HR, datasets/DF2K/DF2K_multiscale --root datasets/DF2K, datasets/DF2K --meta_info datasets/DF2K/meta_info/meta_info_DF2Kmultiscale.txt
|
| 71 |
+
```
|
| 72 |
+
|
| 73 |
+
### 训练 Real-ESRNet 模型
|
| 74 |
+
|
| 75 |
+
1. 下载预先训练的模型 [ESRGAN](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.1/ESRGAN_SRx4_DF2KOST_official-ff704c30.pth)，放到 `experiments/pretrained_models`目录下。
|
| 76 |
+
```bash
|
| 77 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.1/ESRGAN_SRx4_DF2KOST_official-ff704c30.pth -P experiments/pretrained_models
|
| 78 |
+
```
|
| 79 |
+
2. 相应地修改选项文件 `options/train_realesrnet_x4plus.yml` 中的内容：
|
| 80 |
+
```yml
|
| 81 |
+
train:
|
| 82 |
+
name: DF2K+OST
|
| 83 |
+
type: RealESRGANDataset
|
| 84 |
+
dataroot_gt: datasets/DF2K # 修改为你的数据集文件夹根目录
|
| 85 |
+
meta_info: realesrgan/meta_info/meta_info_DF2Kmultiscale+OST_sub.txt # 修改为你自己生成的元信息txt
|
| 86 |
+
io_backend:
|
| 87 |
+
type: disk
|
| 88 |
+
```
|
| 89 |
+
3. 如果你想在训练过程中执行验证，就取消注释这些内容并进行相应的修改：
|
| 90 |
+
```yml
|
| 91 |
+
# 取消注释这些以进行验证
|
| 92 |
+
# val:
|
| 93 |
+
# name: validation
|
| 94 |
+
# type: PairedImageDataset
|
| 95 |
+
# dataroot_gt: path_to_gt
|
| 96 |
+
# dataroot_lq: path_to_lq
|
| 97 |
+
# io_backend:
|
| 98 |
+
# type: disk
|
| 99 |
+
|
| 100 |
+
...
|
| 101 |
+
|
| 102 |
+
# 取消注释这些以进行验证
|
| 103 |
+
# 验证设置
|
| 104 |
+
# val:
|
| 105 |
+
# val_freq: !!float 5e3
|
| 106 |
+
# save_img: True
|
| 107 |
+
|
| 108 |
+
# metrics:
|
| 109 |
+
# psnr: # 指标名称，可以是任意的
|
| 110 |
+
# type: calculate_psnr
|
| 111 |
+
# crop_border: 4
|
| 112 |
+
# test_y_channel: false
|
| 113 |
+
```
|
| 114 |
+
4. 正式训练之前，你可以用 `--debug` 模式检查是否正常运行。我们用了4个GPU进行训练：
|
| 115 |
+
```bash
|
| 116 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 117 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --launcher pytorch --debug
|
| 118 |
+
```
|
| 119 |
+
|
| 120 |
+
用 **1个GPU** 训练的 debug 模式示例:
|
| 121 |
+
```bash
|
| 122 |
+
python realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --debug
|
| 123 |
+
```
|
| 124 |
+
5. 正式训练开始。我们用了4个GPU进行训练。还可以使用参数 `--auto_resume` 在必要时自动恢复训练。
|
| 125 |
+
```bash
|
| 126 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 127 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --launcher pytorch --auto_resume
|
| 128 |
+
```
|
| 129 |
+
|
| 130 |
+
用 **1个GPU** 训练：
|
| 131 |
+
```bash
|
| 132 |
+
python realesrgan/train.py -opt options/train_realesrnet_x4plus.yml --auto_resume
|
| 133 |
+
```
|
| 134 |
+
|
| 135 |
+
### 训练 Real-ESRGAN 模型
|
| 136 |
+
|
| 137 |
+
1. 训练 Real-ESRNet 模型后，您得到了这个 `experiments/train_RealESRNetx4plus_1000k_B12G4_fromESRGAN/model/net_g_1000000.pth` 文件。如果需要指定预训练路径到其他文件，请修改选项文件 `train_realesrgan_x4plus.yml` 中 `pretrain_network_g` 的值。
|
| 138 |
+
1. 修改选项文件 `train_realesrgan_x4plus.yml` 的内容。大多数修改与上节提到的类似。
|
| 139 |
+
1. 正式训练之前，你可以以 `--debug` 模式检查是否正常运行。我们使用了4个GPU进行训练：
|
| 140 |
+
```bash
|
| 141 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 142 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --launcher pytorch --debug
|
| 143 |
+
```
|
| 144 |
+
|
| 145 |
+
用 **1个GPU** 训练的 debug 模式示例:
|
| 146 |
+
```bash
|
| 147 |
+
python realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --debug
|
| 148 |
+
```
|
| 149 |
+
1. 正式训练开始。我们使用4个GPU进行训练。还可以使用参数 `--auto_resume` 在必要时自动恢复训练。
|
| 150 |
+
```bash
|
| 151 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 152 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --launcher pytorch --auto_resume
|
| 153 |
+
```
|
| 154 |
+
|
| 155 |
+
用 **1个GPU** 训练：
|
| 156 |
+
```bash
|
| 157 |
+
python realesrgan/train.py -opt options/train_realesrgan_x4plus.yml --auto_resume
|
| 158 |
+
```
|
| 159 |
+
|
| 160 |
+
## 用自己的数据集微调 Real-ESRGAN
|
| 161 |
+
|
| 162 |
+
你可以用自己的数据集微调 Real-ESRGAN。一般地，微调（Fine-Tune）程序可以分为两种类型:
|
| 163 |
+
|
| 164 |
+
1. [动态生成降级图像](#动态生成降级图像)
|
| 165 |
+
2. [使用**已配对**的数据](#使用已配对的数据)
|
| 166 |
+
|
| 167 |
+
### 动态生成降级图像
|
| 168 |
+
|
| 169 |
+
只需要高分辨率图像。在训练过程中，使用 Real-ESRGAN 描述的降级模型生成低质量图像。
|
| 170 |
+
|
| 171 |
+
**1. 准备数据集**
|
| 172 |
+
|
| 173 |
+
完整信息请参见[本节](#准备数据集)。
|
| 174 |
+
|
| 175 |
+
**2. 下载预训练模型**
|
| 176 |
+
|
| 177 |
+
下载预先训练的模型到 `experiments/pretrained_models` 目录下。
|
| 178 |
+
|
| 179 |
+
- *RealESRGAN_x4plus.pth*:
|
| 180 |
+
```bash
|
| 181 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.0/RealESRGAN_x4plus.pth -P experiments/pretrained_models
|
| 182 |
+
```
|
| 183 |
+
|
| 184 |
+
- *RealESRGAN_x4plus_netD.pth*:
|
| 185 |
+
```bash
|
| 186 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.3/RealESRGAN_x4plus_netD.pth -P experiments/pretrained_models
|
| 187 |
+
```
|
| 188 |
+
|
| 189 |
+
**3. 微调**
|
| 190 |
+
|
| 191 |
+
修改选项文件 [options/finetune_realesrgan_x4plus.yml](options/finetune_realesrgan_x4plus.yml) ，特别是 `datasets` 部分：
|
| 192 |
+
|
| 193 |
+
```yml
|
| 194 |
+
train:
|
| 195 |
+
name: DF2K+OST
|
| 196 |
+
type: RealESRGANDataset
|
| 197 |
+
dataroot_gt: datasets/DF2K # 修改为你的数据集文件夹根目录
|
| 198 |
+
meta_info: realesrgan/meta_info/meta_info_DF2Kmultiscale+OST_sub.txt # 修改为你自己生成的元信息txt
|
| 199 |
+
io_backend:
|
| 200 |
+
type: disk
|
| 201 |
+
```
|
| 202 |
+
|
| 203 |
+
我们使用4个GPU进行训练。还可以使用参数 `--auto_resume` 在必要时自动恢复训练。
|
| 204 |
+
|
| 205 |
+
```bash
|
| 206 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 207 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/finetune_realesrgan_x4plus.yml --launcher pytorch --auto_resume
|
| 208 |
+
```
|
| 209 |
+
|
| 210 |
+
用 **1个GPU** 训练：
|
| 211 |
+
```bash
|
| 212 |
+
python realesrgan/train.py -opt options/finetune_realesrgan_x4plus.yml --auto_resume
|
| 213 |
+
```
|
| 214 |
+
|
| 215 |
+
### 使用已配对的数据
|
| 216 |
+
|
| 217 |
+
你还可以用自己已经配对的数据微调 RealESRGAN。这个过程更类似于微调 ESRGAN。
|
| 218 |
+
|
| 219 |
+
**1. 准备数据集**
|
| 220 |
+
|
| 221 |
+
假设你已经有两个文件夹（folder）:
|
| 222 |
+
|
| 223 |
+
- **gt folder**（标准参考，高分辨率图像）：*datasets/DF2K/DIV2K_train_HR_sub*
|
| 224 |
+
- **lq folder**（低质量，低分辨率图像）：*datasets/DF2K/DIV2K_train_LR_bicubic_X4_sub*
|
| 225 |
+
|
| 226 |
+
然后，您可以使用脚本 [scripts/generate_meta_info_pairdata.py](scripts/generate_meta_info_pairdata.py) 生成元信息（meta_info）txt 文件。
|
| 227 |
+
|
| 228 |
+
```bash
|
| 229 |
+
python scripts/generate_meta_info_pairdata.py --input datasets/DF2K/DIV2K_train_HR_sub datasets/DF2K/DIV2K_train_LR_bicubic_X4_sub --meta_info datasets/DF2K/meta_info/meta_info_DIV2K_sub_pair.txt
|
| 230 |
+
```
|
| 231 |
+
|
| 232 |
+
**2. 下载预训练模型**
|
| 233 |
+
|
| 234 |
+
下载预先训练的模型到 `experiments/pretrained_models` 目录下。
|
| 235 |
+
|
| 236 |
+
- *RealESRGAN_x4plus.pth*:
|
| 237 |
+
```bash
|
| 238 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.0/RealESRGAN_x4plus.pth -P experiments/pretrained_models
|
| 239 |
+
```
|
| 240 |
+
|
| 241 |
+
- *RealESRGAN_x4plus_netD.pth*:
|
| 242 |
+
```bash
|
| 243 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.3/RealESRGAN_x4plus_netD.pth -P experiments/pretrained_models
|
| 244 |
+
```
|
| 245 |
+
|
| 246 |
+
**3. 微调**
|
| 247 |
+
|
| 248 |
+
修改选项文件 [options/finetune_realesrgan_x4plus_pairdata.yml](options/finetune_realesrgan_x4plus_pairdata.yml) ，特别是 `datasets` 部分：
|
| 249 |
+
|
| 250 |
+
```yml
|
| 251 |
+
train:
|
| 252 |
+
name: DIV2K
|
| 253 |
+
type: RealESRGANPairedDataset
|
| 254 |
+
dataroot_gt: datasets/DF2K # 修改为你的 gt folder 文件夹根目录
|
| 255 |
+
dataroot_lq: datasets/DF2K # 修改为你的 lq folder 文件夹根目录
|
| 256 |
+
meta_info: datasets/DF2K/meta_info/meta_info_DIV2K_sub_pair.txt # 修改为你自己生成的元信息txt
|
| 257 |
+
io_backend:
|
| 258 |
+
type: disk
|
| 259 |
+
```
|
| 260 |
+
|
| 261 |
+
我们使用4个GPU进行训练。还可以使用参数 `--auto_resume` 在必要时自动恢复训练。
|
| 262 |
+
|
| 263 |
+
```bash
|
| 264 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 \
|
| 265 |
+
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 realesrgan/train.py -opt options/finetune_realesrgan_x4plus_pairdata.yml --launcher pytorch --auto_resume
|
| 266 |
+
```
|
| 267 |
+
|
| 268 |
+
用 **1个GPU** 训练：
|
| 269 |
+
```bash
|
| 270 |
+
python realesrgan/train.py -opt options/finetune_realesrgan_x4plus_pairdata.yml --auto_resume
|
| 271 |
+
```

+
### PyTorch Inference
|
| 22 |
+
|
| 23 |
+
Pre-trained models: [RealESRGAN_x4plus_anime_6B](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.4/RealESRGAN_x4plus_anime_6B.pth)
|
| 24 |
+
|
| 25 |
+
```bash
|
| 26 |
+
# download model
|
| 27 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.4/RealESRGAN_x4plus_anime_6B.pth -P weights
|
| 28 |
+
# inference
|
| 29 |
+
python inference_realesrgan.py -n RealESRGAN_x4plus_anime_6B -i inputs
|
| 30 |
+
```
|
| 31 |
+
|
| 32 |
+
### ncnn Executable File
|
| 33 |
+
|
| 34 |
+
Download the latest portable [Windows](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-windows.zip) / [Linux](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-ubuntu.zip) / [MacOS](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-macos.zip) **executable files for Intel/AMD/Nvidia GPU**.
|
| 35 |
+
|
| 36 |
+
Taking the Windows as example, run:
|
| 37 |
+
|
| 38 |
+
```bash
|
| 39 |
+
./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n realesrgan-x4plus-anime
|
| 40 |
+
```
|
| 41 |
+
|
| 42 |
+
## Comparisons with waifu2x
|
| 43 |
+
|
| 44 |
+
We compare Real-ESRGAN-anime with [waifu2x](https://github.com/nihui/waifu2x-ncnn-vulkan). We use the `-n 2 -s 4` for waifu2x.

## How to Use
|
| 32 |
+
|
| 33 |
+
### PyTorch Inference
|
| 34 |
+
|
| 35 |
+
```bash
|
| 36 |
+
# download model
|
| 37 |
+
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesr-animevideov3.pth -P weights
|
| 38 |
+
# single gpu and single process inference
|
| 39 |
+
CUDA_VISIBLE_DEVICES=0 python inference_realesrgan_video.py -i inputs/video/onepiece_demo.mp4 -n realesr-animevideov3 -s 2 --suffix outx2
|
| 40 |
+
# single gpu and multi process inference (you can use multi-processing to improve GPU utilization)
|
| 41 |
+
CUDA_VISIBLE_DEVICES=0 python inference_realesrgan_video.py -i inputs/video/onepiece_demo.mp4 -n realesr-animevideov3 -s 2 --suffix outx2 --num_process_per_gpu 2
|
| 42 |
+
# multi gpu and multi process inference
|
| 43 |
+
CUDA_VISIBLE_DEVICES=0,1,2,3 python inference_realesrgan_video.py -i inputs/video/onepiece_demo.mp4 -n realesr-animevideov3 -s 2 --suffix outx2 --num_process_per_gpu 2
|
| 44 |
+
```
|
| 45 |
+
|
| 46 |
+
```console
|
| 47 |
+
Usage:
|
| 48 |
+
--num_process_per_gpu The total number of process is num_gpu * num_process_per_gpu. The bottleneck of
|
| 49 |
+
the program lies on the IO, so the GPUs are usually not fully utilized. To alleviate
|
| 50 |
+
this issue, you can use multi-processing by setting this parameter. As long as it
|
| 51 |
+
does not exceed the CUDA memory
|
| 52 |
+
--extract_frame_first If you encounter ffmpeg error when using multi-processing, you can turn this option on.
|
| 53 |
+
```
|
| 54 |
+
|
| 55 |
+
### NCNN Executable File
|
| 56 |
+
|
| 57 |
+
#### Step 1: Use ffmpeg to extract frames from video
|
| 58 |
+
|
| 59 |
+
```bash
|
| 60 |
+
ffmpeg -i onepiece_demo.mp4 -qscale:v 1 -qmin 1 -qmax 1 -vsync 0 tmp_frames/frame%08d.png
|
| 61 |
+
```
|
| 62 |
+
|
| 63 |
+
- Remember to create the folder `tmp_frames` ahead
|
| 64 |
+
|
| 65 |
+
#### Step 2: Inference with Real-ESRGAN executable file
|
| 66 |
+
|
| 67 |
+
1. Download the latest portable [Windows](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-windows.zip) / [Linux](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-ubuntu.zip) / [MacOS](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-macos.zip) **executable files for Intel/AMD/Nvidia GPU**
|
| 68 |
+
|
| 69 |
+
1. Taking the Windows as example, run:
|
| 70 |
+
|
| 71 |
+
```bash
|
| 72 |
+
./realesrgan-ncnn-vulkan.exe -i tmp_frames -o out_frames -n realesr-animevideov3 -s 2 -f jpg
|
| 73 |
+
```
|
| 74 |
+
|
| 75 |
+
- Remember to create the folder `out_frames` ahead
|
| 76 |
+
|
| 77 |
+
#### Step 3: Merge the enhanced frames back into a video
|
| 78 |
+
|
| 79 |
+
1. First obtain fps from input videos by
|
| 80 |
+
|
| 81 |
+
```bash
|
| 82 |
+
ffmpeg -i onepiece_demo.mp4
|
| 83 |
+
```
|
| 84 |
+
|
| 85 |
+
```console
|
| 86 |
+
Usage:
|
| 87 |
+
-i input video path
|
| 88 |
+
```
|
| 89 |
+
|
| 90 |
+
You will get the output similar to the following screenshot.
|
| 91 |
+
|
| 92 |
+
<p align="center">
|
| 93 |
+
<img src="https://user-images.githubusercontent.com/17445847/145710145-c4f3accf-b82f-4307-9f20-3803a2c73f57.png">
|
| 94 |
+
</p>
|
| 95 |
+
|
| 96 |
+
2. Merge frames
|
| 97 |
+
|
| 98 |
+
```bash
|
| 99 |
+
ffmpeg -r 23.98 -i out_frames/frame%08d.jpg -c:v libx264 -r 23.98 -pix_fmt yuv420p output.mp4
|
| 100 |
+
```
|
| 101 |
+
|
| 102 |
+
```console
|
| 103 |
+
Usage:
|
| 104 |
+
-i input video path
|
| 105 |
+
-c:v video encoder (usually we use libx264)
|
| 106 |
+
-r fps, remember to modify it to meet your needs
|
| 107 |
+
-pix_fmt pixel format in video
|
| 108 |
+
```
|
| 109 |
+
|
| 110 |
+
If you also want to copy audio from the input videos, run:
|
| 111 |
+
|
| 112 |
+
```bash
|
| 113 |
+
ffmpeg -r 23.98 -i out_frames/frame%08d.jpg -i onepiece_demo.mp4 -map 0:v:0 -map 1:a:0 -c:a copy -c:v libx264 -r 23.98 -pix_fmt yuv420p output_w_audio.mp4
|
| 114 |
+
```
|
| 115 |
+
|
| 116 |
+
```console
|
| 117 |
+
Usage:
|
| 118 |
+
-i input video path, here we use two input streams
|
| 119 |
+
-c:v video encoder (usually we use libx264)
|
| 120 |
+
-r fps, remember to modify it to meet your needs
|
| 121 |
+
-pix_fmt pixel format in video
|
| 122 |
+
```
|
| 123 |
+
|
| 124 |
+

## 动漫插画模型
|
| 4 |
+
|
| 5 |
+
1. 视频处理不了: 目前的模型，不是针对视频的，所以视频效果很很不好。我们在探究针对视频的模型了
|
| 6 |
+
1. 景深虚化有问题: 现在的模型把一些景深 和 特意的虚化 都复原了，感觉不好。这个后面我们会考虑把这个信息结合进入。一个简单的做法是识别景深和虚化，然后作为条件告诉神经网络，哪些地方复原强一些，哪些地方复原要弱一些
|
| 7 |
+
1. 不可以调节: 像 Waifu2X 可以调节。可以根据自己的喜好，做调整，但是 Real-ESRGAN-anime 并不可以。导致有些恢复效果过了
|
| 8 |
+
1. 把原来的风格改变了: 不同的动漫插画都有自己的风格，现在的 Real-ESRGAN-anime 倾向于恢复成一种风格（这是受到训练数据集影响的）。风格是动漫很重要的一个要素，所以要尽可能保持
|
| 9 |
+
1. 模型太大: 目前的模型处理太慢，能够更快。这个我们有相关的工作在探究，希望能够尽快有结果，并应用到 Real-ESRGAN 这一系列的模型上
