Building OCRopus (quick start)
--------------------------------------------------------------------------------
1) make sure you have these packages installed (current Ubuntu/Debian versions should work):
    libpng (with headers)
    libjpeg (with headers)
    libtiff (with headers)

2) install iulib from http://code.google.com/p/iulib

3) install a current version of tesseract from the Subversion repository
    (http://code.google.com/p/tesseract-ocr)

4) from the release directory, run
    ./configure
    make
    sudo make install

Please refer to the file INSTALL for more help on building OCRopus from source.

Background
--------------------------------------------------------------------------------
OCRopus 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.
OCRopus 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.

OCRopus is mainly based on research projects of Thomas Breuel and the Image
Understanding and Pattern Recognition (IUPR) group of the German Research
Center for Artificial Intelligence (DFKI) located in Kaiserslautern, Germany.

OCRopus uses data structures and algorithms from iulib - the open source 
Image Understanding Library (http://code.google.com/p/iulib/) which has
been part of OCRopus until June 2008.
