OCR, printed documents, page layout analysis, text recognition, language model, Python

This Python package implements the entire OCR pipeline, including page layout analysis, text line detection, text recognition, and text decoding using a language model. The software is focused on processing of low-quality documents (for example documents digitized from microfilms). The package provides a command-line tool and a class that can be integrated into your own software.
