Usage

import jaidedread
reader = jaidedread.Reader(['th','en'])
reader.readtext('test.jpg')

Model weight for chosen language will be automatically downloaded or you can download it manually from https://jaided.ai/read_download and put it in 'model' folder.

Output will be in list format, each item represents bounding box, text and confident level, respectively.

[([[1344, 439], [2168, 439], [2168, 580], [1344, 580]], 'ใจเด็ด', 0.4542357623577118),

Better documentation and api

Acknowledgement and References

This project is based on researches/codes from several papers/open-source repositories.

Detection part is using CRAFT algorithm from this official repository and their paper.

Recognition model is CRNN (paper). It is composed of 3 main components, feature extraction (we are currently using Resnet), sequence labeling (LSTM) and decoding (CTC). Training pipeline for recognition part is a modified version from this repository.

Beam search code is based on this repository and his blog.

And good read about CTC from distill.pub here.
