# Myanmar OCR Dataset

A synthetic dataset for training and fine-tuning Optical Character Recognition (OCR) models specifically for the Myanmar language.

## Dataset Description

This dataset contains synthetically generated OCR images created specifically for Myanmar text recognition tasks. The images were generated using [myanmar-ocr-data-generator](https://github.com/chuuhtetnaing/myanmar-ocr-data-generator), a fork of [TextRecognitionDataGenerator](https://github.com/Belval/TextRecognitionDataGenerator) with fixes for proper Myanmar character splitting.

## Direct Download

Available from [UT Austin SharePoint](https://utexas-my.sharepoint.com/:u:/g/personal/cn23349_my_utexas_edu/EZcWC2NEbKNMkeJ_WByugx0BMTSE6qKYQjVp62fn6m0toA?e=L9AKko)
   - The downloadable data is specifically formatted for PaddleOCR
   - Includes organized folder structure optimized for PaddleOCR training
   - Labels are provided in tab-separated format
   - Ready to fine-tuned for PaddleOCR

### Key Features

- Synthetic Myanmar text images with corresponding text labels
- Maximum text length of 100 characters per image
- Various fonts, styles, skews, various distortion types, blur levels, and backgrounds to improve model robustness

## Generation Method

The dataset was created using a forked and customized version of the TextRecognitionDataGenerator:
- Original repository: [Belval/TextRecognitionDataGenerator](https://github.com/Belval/TextRecognitionDataGenerator)
- Customized fork: [chuuhtetnaing/myanmar-ocr-data-generator](https://github.com/chuuhtetnaing/myanmar-ocr-data-generator)

### Text Sources

The text content used to generate the OCR images was extracted from:
- [chuuhtetnaing/myanmar-wikipedia-dataset](https://huggingface.co/datasets/chuuhtetnaing/myanmar-wikipedia-dataset): A collection of Myanmar language text from Wikipedia
- [chuuhtetnaing/myanmar-facebook-flores-dataset](https://huggingface.co/datasets/chuuhtetnaing/myanmar-facebook-flores-dataset): A subset of [Meta's FLORES dataset](https://huggingface.co/datasets/facebook/flores) containing only Myanmar language text
- [chuuhtetnaing/myanmar-instruction-tuning-dataset](https://huggingface.co/datasets/chuuhtetnaing/myanmar-instruction-tuning-dataset): Compilation of question-answer pairs in the Myanmar language
- [chuuhtetnaing/mm-lib-book-dataset](https://huggingface.co/datasets/chuuhtetnaing/mm-lib-book-dataset): A dataset of 437 books extracted from MM-Lib (Only 421 unicode font books are used for OCR dataset)

## Usage

This dataset is particularly useful for:

- Training OCR models for Myanmar language text recognition
- Fine-tuning existing OCR models to improve performance on Myanmar script
- Developing applications for Myanmar text digitization

## License

This dataset is free to use for any purpose - personal, commercial, or educational.
