This package intends to give a common interface for multiple ocr backends
pip install multiocr
- Tesseract
- PaddleOCR
- Aws Textract
- EasyOCR
- Doctr-Ocr
the output for all ocr backend will be simillar

plain_text = engine.extract_plain_text(text_dict)if you want to access the output of each individual ocr engine in their own raw format, we can fetch it this way
raw_ocr_output = engine.engine.raw_ocr
config is the each ocr's input parameters and it should be python dictionary. if not given, it'll default to each respective libraries default parameters
the input parameters for each ocr differs, and you can look at its respective repo for all allowable parameters
