ocrpy

Unified interface to google vision, aws textract, azure, tesseract and other OCR tools

The core objective of ocrpy is to let users perform OCR, archive, index and search any document with ease, providing an intuitive interface and a powerful Pipeline API to solve common OCR-based tasks.

ocrpy achieves this by wrapping around the most popular OCR engines like Tesseract OCR, Aws Textract, Google Cloud Vision and Azure Computer Vision. It unifies the multitude of interfaces provided by a wide range of cloud tools & other open-source libraries under a common and easy-to-use interface for the user.

Getting Started

ocrpy is a Python-only package hosted on PyPI. The recommended installation method is pip

pip install ocrpy

Day-to-Day Usage

ocrpy provides various levels of abstraction for the user to perform OCR on different types of documents. The recommended and the best way to use ocrpy is through it's pipeline API as shown below.

The Pipeline API can be invoked in two ways. The first method is to define the config for running the pipeline as a yaml file and and then run the pipeline by loading it as follows:

   from ocrpy import TextOcrPipeline

   ocr_pipeline = TextOcrPipeline.from_config("ocrpy_config.yaml")
   ocr_pipeline.process()

Alternatively you can run a pipeline by directly instantiating the pipeline class as follows:

   from ocrpy import TextOcrPipeline

   pipeline = TextOcrPipeline(source_dir='s3://document_bucket/', 
                              destination_dir="gs://processed_document_bucket/outputs/", 
                              parser_backend='aws-textract', 
                              credentials_config={"AWS": "path/to/aws-credentials.env/file", 
                                           "GCP": "path/to/gcp-credentials.json/file"})
   pipeline.process()
