Document image analysis with OCRopus

Document image analysis is the field of converting paper documents into an editable electronic representation by performing optical character recognition (OCR). In recent years, there has been a tremendous amount of progress in the development of open source OCR systems. OCRopus is one of the leading open source document analysis system with a modular and pluggable architecture. This paper presents an overview of different steps involved in a document image analysis system and illustrates them with examples from OCRopus.
