How to run UNLV tests.

The scripts in this directory make it possible to duplicate the tests published in the Fourth Annual Test of OCR Accuracy. See http://www.isri.unlv.edu/downloads/AT-1995.pdf but first you have to get the tools and data used by UNLV:

Step 1: to download the images go to https://sourceforge.net/projects/isri-ocr-evaluation-tools-alt/files/ and get doe3.3B.tar.gz, bus.3B.tar.gz, mag.3B.tar.gz and news.3B.tar.gz spn.3B.tar.gz is incorrect in this repo, so get it from code.google

mkdir -p ~/isri-downloads cd ~/isri-downloads curl -L https://sourceforge.net/projects/isri-ocr-evaluation-tools-alt/files/bus.3B.tar.gz > bus.3B.tar.gz curl -L https://sourceforge.net/projects/isri-ocr-evaluation-tools-alt/files/doe3.3B.tar.gz > doe3.3B.tar.gz curl -L https://sourceforge.net/projects/isri-ocr-evaluation-tools-alt/files/mag.3B.tar.gz > mag.3B.tar.gz curl -L https://sourceforge.net/projects/isri-ocr-evaluation-tools-alt/files/news.3B.tar.gz > news.3B.tar.gz curl -L https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/isri-ocr-evaluation-tools/spn.3B.tar.gz > spn.3B.tar.gz

Step 2: extract the files. It doesn't really matter where in your filesystem you put them, but they must go under a common root so you have directories doe3.3B, bus.3B, mag.3B and news.3B. in, for example, ~/ISRI-OCRtk.

mkdir -p ~/ISRI-OCRtk cd ~/ISRI-OCRtk tar xzvf ~/isri-downloads/bus.3B.tar.gz tar xzvf ~/isri-downloads/doe3.3B.tar.gz tar xzvf ~/isri-downloads/mag.3B.tar.gz tar xzvf ~/isri-downloads/news.3B.tar.gz tar xzvf ~/isri-downloads/spn.3B.tar.gz

**** Edit ~/ISRI-OCRtk/spn.3B/pages delete the line containing the following imagename as it crashes tesseract. 7733_005.3B.tif

Step 4: Download the modified ISRI toolkit and make and install the tools :

git clone https://github.com/Shreeshrii/ocr-evaluation-tools.git cd ~/ocr-evaluation-tools sudo make install

Step 6: cd back to your main tesseract-ocr dir and Build tesseract.

Step 7: run unlvtests/runalltests.sh with the root ISRI data dir and testname, tessdata-dir and language:

unlvtests/runalltests.sh ~/ISRI-OCRtk 4_fast_eng ../tessdata_fast eng and go to the gym, have lunch etc.

Step 8: There should be a file unlvtests/reports/4-beta_fast.summary that contains the final summarized accuracy report and comparison with the 1995 results.

unlvtests/runalltests.sh ~/ISRI-OCRtk 4_fast_spa ../tessdata_fast spa
