How to run UNLV tests.
## 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
See http://www.expervision.com/wp-content/uploads/2012/12/1995.The_Fourth_Annual_Test_of_OCR_Accuracy.pdf
but first you have to get the tools and data used by UNLV:
Step 1: to download the images goto
### 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
### 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
```
Step 4: Download the modified ISRI toolkit from:
https://ancientgreekocr.org/ocr-evaluation-tools.git
Edit *~/ISRI-OCRtk/spn.3B/pages*
delete the line containing the following imagename as it crashes tesseract.
make and install the tools in unlvtests/ocreval/bin by
`make PREFIX=~/tesseract/unlvtests/ocreval install`
7733_005.3B.tif
Step 6: cd back to your main tesseract-ocr dir and Build tesseract.
### Step 3: Download the modified ISRI toolkit, make and install the tools :
These will be installed in /usr/local/bin.
Step 7: run unlvtests/runalltests.sh with the root ISRI data dir and testname:
unlvtests/runalltests.sh ~/ISRI-OCRtk tess4.0.0-beta.1
and go to the gym, have lunch etc.
```
git clone https://github.com/Shreeshrii/ocr-evaluation-tools.git
cd ~/ocr-evaluation-tools
sudo make install
```
Step 8: There should be a file
unlvtests/reports/tess4.0.0-beta.1.summary that contains the final summarized accuracy
### Step 4: cd back to your main tesseract-ocr dir and Build tesseract.
### Step 5: run unlvtests/runalltests.sh with the root ISRI data dir, testname, tessdata-dir and language:
```
unlvtests/runalltests.sh ~/ISRI-OCRtk 4_fast_eng ../tessdata_fast eng
```
and go to the gym, have lunch etc. It takes a while to run.
### Step 6: There should be a RELEASE.summary file
*unlvtests/reports/4-beta_fast.summary* that contains the final summarized accuracy
report and comparison with the 1995 results.
### Step 7: run the test for Spanish.
```
unlvtests/runalltests.sh ~/ISRI-OCRtk 4_fast_spa ../tessdata_fast spa
```
