About

OCRopus(tm) is a state-of-the-art document analysis and OCR system, featuring pluggable layout analysis, pluggable character recognition, statistical natural language modeling, and multi-lingual capabilities.

The OCRopus engine is based on two research projects: a high-performance handwriting recognizer developed in the mid-90's and deployed by the US Census bureau, and novel high-performance layout analysis methods.

OCRopus is development is sponsored by Google and is initially intended for high-throughput, high-volume document conversion efforts. We expect that it will also be an excellent OCR system for many other applications.

Bugs / Issues / Enhancements

Please use the "Issues" tab above to submit bugs, feature requests, etc.

When submitting bug reports, please keep the following in mind:

Until the beta release (version 0.5) we mainly care about "big stuff" bug reports and failing documents; minor compile issues or cross-platform issues don't matter that much right now. Please also only recognition failures on fairly clean scanned documents for the time being.

Contributing

If you want to contribute code to OCRopus, or if you have a patched version or variant, please use Google's Server Side Clone Support for Mercurial. You can maintain your own variant, add experimental features, etc., and share your patches/changes easily with others even if we haven't incorporated them into the main branch yet.

Acknowledgements

The system is combining the work of many contributors and previous projects. The core developers work at the IUPR research group at the DFKI and gratefully acknowledge funding by Google.
