Recent progress on the OCRopus OCR system

The OCRopus system is an open source OCR system developed for book capture and digital library applications. It is designed to be a multilingual system in which all components are easily pluggable and replaceable. In this paper, I describe recent progress, on-going work, and preliminary results in the development of the OCRopus system, including the new component model, a new line recognizer, a new set of decoders, and language modeling tools.
