-# Language tests.
-The scripts in this directory make it possible to test Accuracy of Tesseract for different languages. 
-## Setup
-### Step 1: If not already installed, download the modified ISRI toolkit, 
-make and install the tools in /usr/local/bin.
-```
-git clone https://github.com/Shreeshrii/ocr-evaluation-tools.git
-cd ~/ocr-evaluation-tools
-sudo make install
-```
-### Step 2: If not alrady built, Build tesseract.
-Use binaries from the tesseract/src/api and tesseract/src/training directory.
-### Step 3
-Download images and corresponding ground truth  text for the language to be tested.
-Each testset should have only one kind of images (eg. tif, png, jpg etc).
-The ground truth text files should have the same base filename with txt extension.
-As needed, modify the filenames and create the `pages` file for each testset.
-Instructions for testing Fraktur and Sanskrit languages are given below as an example.
-## Testing for Fraktur - frk and script/Fraktur
-### Download the images and groundtruth, modify to required format.
-```
-bash -x frk_setup.sh
-```
-### Run tests for Fraktur - frk and script/Fraktur
-```
-bash -x frk_test.sh
-```
-## Testing for Sanskrit - san and script/Devanagari
-### Download the images and groundtruth, modify to required format.
-```
-bash -x deva_setup.sh
-```
-### Run tests 
-```
-bash -x deva_test.sh
-```
-
-### Notes from Nick White regarding wordacc
-
-If you just want to remove all lines which have 100% recognition,
-you can add a 'awk' command like this:
-
-ocrevalutf8 wordacc ground.txt ocr.txt | awk '$3 != 100 {print $0}'  
-results.txt
-
-or if you've already got a results file you want to change, you can do this:
-
-awk '$3 != 100 {print $0}'  results.txt  newresults.txt
-
-If you only want the last sections where things are broken down by
-word, you can add a sed commend, like this:
-
-ocrevalutf8 wordacc ground.txt ocr.txt | sed '/^   Count   Missed %Right   $/,$ 
-!d' | awk '$3 != 100 {print $0}'  results.txt

-## 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.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 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
-mkdir -p stopwords
-cd stopwords
-wget -O spa.stopwords.txt https://raw.githubusercontent.com/stopwords-iso/stopwords-es/master/stopwords-es.txt
-```
-Edit ~/ISRI-OCRtk/stopwords/spa.stopwords.txt
-wordacc uses a space delimited stopwords file, not line delimited.
-s/\n/ /g
-
-Edit ~/ISRI-OCRtk/spn.3B/pages
-Delete the line containing the following imagename as it [crashes tesseract](https://github.com/tesseract-ocr/tesseract/issues/1647#issuecomment-395954717).
-
-7733_005.3B 3
-
-### Step 3: Download the modified ISRI toolkit, make and install the tools :
-These will be installed in /usr/local/bin.
-
-```
-git clone https://github.com/Shreeshrii/ocr-evaluation-tools.git
-cd ~/ocr-evaluation-tools
-sudo make install
-```
-
-### 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:
-
-```
-unlvtests/runalltests.sh ~/ISRI-OCRtk 4_fast_eng ../tessdata_fast
-```
-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_spa.sh ~/ISRI-OCRtk 4_fast_spa ../tessdata_fast
-```
-
-#### Notes from Nick White regarding wordacc
-
-If you just want to remove all lines which have 100% recognition,
-you can add a 'awk' command like this:
-
-ocrevalutf8 wordacc ground.txt ocr.txt | awk '$3 != 100 {print $0}'
-results.txt
-
-or if you've already got a results file you want to change, you can do this:
-
-awk '$3 != 100 {print $0}'  results.txt  newresults.txt
-
-If you only want the last sections where things are broken down by
-word, you can add a sed command, like this:
-
-ocrevalutf8 wordacc ground.txt ocr.txt | sed '/^   Count   Missed %Right   $/,$
-!d' | awk '$3 != 100 {print $0}'  results.txt
