About this project

In this project, named "project-O2", my colleague and I implement the methods which we have developed for document analysis and recognition, and release the programs positively, if possible, with source code. The released software is mainly for layout analysis.

Note: No OCR engine is included. Please see NHocr project at Google Code for an OCR engine.

The released packages contain some programs which may be convenient to many researchers, even if no new method is included.

Limitations

The released programs have following limitations.

• Unpublished new methods are basically not included except in some binary distributions.
• Not all the published methods are provided.
• Some minor improvements may be added to the published method.
• Some minor modifications may be incorporated without a great change of the result of processing.
• The source codes in the packages are not always easy to read or to understand, because the programs are originally made for my private experiments.

There are some limitations to use the released programs.

• The programs are basically regarded as "Free Software", but not "PDS(Public Domain Software)". All rights are reserved.
• I would greatly appreciate your bug-reports. However, I do not always support the programs. I do it when I want to do.
