Google Vision API

We use OCR of Google Vision API. So first, you need to set up Google Vision API Environment. https://cloud.google.com/vision

You need to get a service account key, and set the key path to OCR_KEY_PATH in private_const.py.

DEEPL API

We use DeepL. You need to get DeepL API Key, and set DEEPL_AUTH_KEY in private_const.py.

Font

For kivy GUI System, download mplus-2c-regular.ttf, put under fonts. https://www.wfonts.com/font/m-2c

$ mkdir fonts
$ mv path/to/mplus-2c-regular.ttf fonts

For GIMP Output, install Helsinki. https://www.dafont.com/helsinki.font

How to Use

1. Detect texts by OCR

Put images under some directory (INPUT_DIR), like sample_imgs.
Run the following command, you can get ocr result images and jsons.

$ python ocr.py -i <INPUT_DIR> -o <OCR_OUTPUT_DIR>

2. (Additional Step) Fix OCR Results

Currently, OCR precision is not good enouth. It is better to fix results in gui. you can

• Remove abundant Box.
• Fix text contents.

$ python refine.py <OCR_OUTPUT_DIR>/jp_json

3. Translation

Run the following command, you can get gimp format data under OCR_OUTPUT_DIR/gimp.

$ python translate.py -i <OCR_OUTPUT_DIR> --is_translate

Output Setting

You can control output font {size, type}, {input, output} language in const.py
