Some manga/images will never be translated, therefore this project is born.
Please note that the samples may not always be updated, they may not represent the current main branch version.

- Note this may not work sometimes due to stupid google gcp kept restarting my instance. In that case you can wait for me to restart the service, which may take up to 24 hrs.
- Note this online demo is using the current main branch version.
Successor to MMDOCR-HighPerformance.
This is a hobby project, you are welcome to contribute!
Currently this only a simple demo, many imperfections exist, we need your support to make this project better!
Primarily designed for translating Japanese text, but also supports Chinese, English and Korean.
Supports inpainting, text rendering and colorization.
# First, you need to have Python(>=3.8) installed on your system
# The latest version often does not work with some pytorch libraries yet
$ python --version
Python 3.10.6
# Clone this repo
$ git clone https://github.com/zyddnys/manga-image-translator.git
# Create venv
$ python -m venv venv
# Activate venv
$ source venv/bin/activate
# For --use-gpu option go to https://pytorch.org/ and follow
# pytorch installation instructions. Add `--upgrade --force-reinstall`
# to the pip command to overwrite the currently installed pytorch version.
# Install the dependencies
$ pip install -r requirements.txt
$ pip install git+https://github.com/kodalli/pydensecrf.gitgit clone https://github.com/zyddnys/manga-image-translator.git
cd manga-image-translator
poetry shell
poetry installThe models will be downloaded into ./models at runtime.
Before you start the pip install, first install Microsoft C++ Build Tools (Download, Instructions) as some pip dependencies will not compile without it. (See #114).
To use cuda on windows install the correct pytorch version as instructed on https://pytorch.org/.
Also, if you have trouble installing pydensecrf with the command above you can install the pre-compiled wheels
with pip install https://www.lfd.uci.edu/~gohlke/pythonlibs/#_pydensecrf.
Requirements:
- Docker (version 19.03+ required for CUDA / GPU acceleration)
- Docker Compose (Optional if you want to use files in the
demo/docfolder) - Nvidia Container Runtime (Optional if you want to use CUDA)
This project has docker support under zyddnys/manga-image-translator:main image.
This docker image contains all required dependencies / models for the project.
It should be noted that this image is fairly large (~ 15GB).
The web server can be hosted using (For CPU)
docker run -p 5003:5003 -v result:/app/result --ipc=host --rm zyddnys/manga-image-translator:main -l ENG --manga2eng -v --mode web --host=0.0.0.0 --port=5003or
docker-compose -f demo/doc/docker-compose-web-with-cpu.yml updepending on which you prefer. The web server should start on port 5003
and images should become in the /result folder.
To use docker with the CLI (I.e in batch mode)
docker run -v <targetFolder>:/app/<targetFolder> -v <targetFolder>-translated:/app/<targetFolder>-translated --ipc=host --rm zyddnys/manga-image-translator:main --mode=batch -i=/app/<targetFolder> <cli flags>Note: In the event you need to reference files on your host machine
you will need to mount the associated files as volumes into the /app folder inside the container.
Paths for the CLI will need to be the internal docker path /app/... instead of the paths on your host machine
Some translation services require API keys to function to set these pass them as env vars into the docker container. For example:
docker run --env="DEEPL_AUTH_KEY=xxx" --ipc=host --rm zyddnys/manga-image-translator:main <cli flags>To use with a supported GPU please first read the initial
Dockersection. There are some special dependencies you will need to use
To run the container with the following flags set:
docker run ... --gpus=all ... zyddnys/manga-image-translator:main ... --use-gpuOr (For the web server + GPU)
docker-compose -f demo/doc/docker-compose-web-with-gpu.yml upTo build the docker image locally you can run (You will require make on your machine)
make build-imageThen to test the built image run
make run-web-server# use `--use-gpu` for speedup if you have a compatible NVIDIA GPU.
# use `--target-lang <language_code>` to specify a target language.
# use `--inpainter=none` to disable inpainting.
# use `--translator=none` if you only want to use inpainting (blank bubbles)
# replace <path> with the path to the image folder or file.
$ python -m manga_translator -v --translator=google -l ENG -i <path>
# results can be found under `<path_to_image_folder>-translated`.# saves singular image into /result folder for demonstration purposes
# use `--mode demo` to enable demo translation.
# replace <path> with the path to the image file.
$ python -m manga_translator --mode demo -v --translator=google -l ENG -i <path>
# result can be found in `result/`.# use `--mode web` to start a web server.
$ python -m manga_translator -v --mode web --use-gpu
# the demo will be serving on http://127.0.0.1:5003# use `--mode web` to start a web server.
$ python -m manga_translator -v --mode api --use-gpu
# the demo will be serving on http://127.0.0.1:5003GUI implementation: BallonsTranslator

- Small resolutions can sometimes trip up the detector, which is not so good at picking up irregular text sizes. To
circumvent this you can use an upscaler by specifying
--upscale-ratio 2or any other value - If the text being rendered is too small to read specify
--font-size-minimum 30for instance or use the--manga2engrenderer that will try to adapt to detected textbubbles - Specify a font with
--font-path fonts/anime_ace_3.ttffor example

# The prompt being feed into GPT before the text to translate.
# Use {to_lang} to indicate where the target language name should be inserted.
# Note: ChatGPT models don't use this prompt.
prompt_template: >
Please help me to translate the following text from a manga to {to_lang}
(if it's already in {to_lang} or looks like gibberish you have to output it as it is instead):\n
# What sampling temperature to use, between 0 and 2.
# Higher values like 0.8 will make the output more random,
# while lower values like 0.2 will make it more focused and deterministic.
temperature: 0.5
# An alternative to sampling with temperature, called nucleus sampling,
# where the model considers the results of the tokens with top_p probability mass.
# So 0.1 means only the tokens comprising the top 10% probability mass are considered.
top_p: 1
# The prompt being feed into ChatGPT before the text to translate.
# Use {to_lang} to indicate where the target language name should be inserted.
# Tokens used in this example: 57+
chat_system_template: >
You are a professional translation engine,
please translate the story into a colloquial,
elegant and fluent content,
without referencing machine translations.
You must only translate the story, never interpret it.
If there is any issue in the text, output it as is.
Translate to {to_lang}.
# Samples being feed into ChatGPT to show an example conversation.
# In a [prompt, response] format, keyed by the target language name.
#
# Generally, samples should include some examples of translation preferences, and ideally
# some names of characters it's likely to encounter.
#
# If you'd like to disable this feature, just set this to an empty list.

<|2|>きみ… 大丈夫⁉
<|3|>なんだこいつ 空気読めて ないのか…？
- <|1|>好尴尬…我不想引人注目…我想消失…
<|2|>你…没事吧⁉
<|3|>这家伙怎么看不懂气氛的…？
# Overwrite configs for a specific model.
# For now the list is: gpt3, gpt35, gpt4
gpt35:
temperature: 0.3When setting output format to {xcf, psd, pdf} Gimp will be used to generate the file.
On Windows this assumes Gimp 2.x to be installed to C:\Users\<Username>\AppData\Local\Programs\Gimp 2.
The resulting .xcf file contains the original image as the lowest layer and it has the inpainting as a separate layer.
The translated textboxes have their own layers with the original text as the layer name for easy access.
Limitations:
- Gimp will turn text layers to regular images when saving
.psdfiles. - Rotated text isn't handled well in Gimp. When editing a rotated textbox it'll also show a popup that it was modified by an outside program.
- Font family is controlled separately, with the
--gimp-fontargument.

Manual translation replaces machine translation with human translators. Basic manual translation demo can be found at http://127.0.0.1:5003/manual when using web mode.
API
Two modes of translation service are provided by the demo: synchronous mode and asynchronous mode.
In synchronous mode your HTTP POST request will finish once the translation task is finished.
In asynchronous mode your HTTP POST request will respond with a task_id immediately, you can use this task_id to
poll for translation task state.
- POST a form request with form data
file:<content-of-image>to http://127.0.0.1:5003/run - Wait for response
- Use the resultant
task_idto find translation result inresult/directory, e.g. using Nginx to exposeresult/
- POST a form request with form data
file:<content-of-image>to http://127.0.0.1:5003/submit - Acquire translation
task_id - Poll for translation task state by posting JSON
{"taskid": <task-id>}to http://127.0.0.1:5003/task-state - Translation is finished when the resultant state is either
finished,errororerror-lang - Find translation result in
result/directory, e.g. using Nginx to exposeresult/
POST a form request with form data file:<content-of-image> to http://127.0.0.1:5003/manual-translate
and wait for response.
You will obtain a JSON response like this:
{
"task_id": "12c779c9431f954971cae720eb104499",
"status": "pending",
"trans_result": [
{
"s": "☆上司来ちゃった……",
"t": ""
}
]
}Fill in translated texts:
{
"task_id": "12c779c9431f954971cae720eb104499",
"status": "pending",
"trans_result": [
{
"s": "☆上司来ちゃった……",
"t": "☆Boss is here..."
}
]
}Post translated JSON to http://127.0.0.1:5003/post-manual-result and wait for response.
Then you can find the translation result in result/ directory, e.g. using Nginx to expose result/.
A list of what needs to be done next, you're welcome to contribute.
- Use diffusion model based inpainting to achieve near perfect result, but this could be much slower.
IMPORTANT!!!HELP NEEDED!!! The current text rendering engine is barely usable, we need your help to improve text rendering!- Text rendering area is determined by detected text lines, not speech bubbles.
This works for images without speech bubbles, but making it impossible to decide where to put translated English text. I have no idea how to solve this. - Ryota et al. proposed using multimodal machine translation, maybe we can add ViT features for building custom NMT models.
- Make this project works for video(rewrite code in C++ and use GPU/other hardware NN accelerator).
Used for detecting hard subtitles in videos, generating ass file and remove them completely. Mask refinement based using non deep learning algorithms, I am currently testing out CRF based algorithm.Angled text region merge is not currently supported- Create pip repository
GPU server is not cheap, please consider to donate to us.
