Installing Tesseract OCR on Ubuntu 14.04

Reference: https://github.com/tesseract-ocr/tesseract/wiki/Compiling
http://hanzratech.in/2015/01/16/ocr-using-tesseract-on-ubuntu-14-04.html

Compilation:

1. clone the package from github
   
   git clone --depth 1 https://github.com/tesseract-ocr/tesseract.git

   1	git clone --depth 1 https://github.com/tesseract-ocr/tesseract.git

2. Go to the new dir
   
   cd tesseract

   1	cd tesseract

3. autogen
   
   ./autogen.sh

   1	./autogen.sh

4. configure
   
   ./configure --enable-debug

   1	./configure --enable-debug

   
   Here i can’t configure it correctly because it always complained about leptonica 1.74
   
   checking pkg-config is at least version 0.9.0... yes checking for LEPTONICA... no configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.

   1 2 3

   checking pkg-config is at least version 0.9.0... yes checking for LEPTONICA... no configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.

   
   I already did
   
   PKG_CONFIG_PATH=/usr/local/lib/pkgconfig LIBLEPT_HEADERSDIR=/usr/local/include ./configure --with-extra-includes=/usr/local/include --with-extra-libraries=/usr/local/lib

   1	PKG_CONFIG_PATH=/usr/local/lib/pkgconfig LIBLEPT_HEADERSDIR=/usr/local/include ./configure --with-extra-includes=/usr/local/include --with-extra-libraries=/usr/local/lib

   
   But the error still persist!
   SOLUTION: I HAVE TO COMPILE AND INSTALL LEPTONICA 1.74 MANUALLY (READ: http://myprojects.advchaweb.com/index.php/2017/02/02/installing-leptonica-1-74-1-on-ubuntu-14-04/)
   NOW IT SUCCESS!

5. Since we have to compile leptonica to use version 1.74, we should use LDFLAGS=”-L/usr/local/lib” CFLAGS=”-I/usr/local/include” make instead of make for Tesseract.

   For the training tutorial, pls read: https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00 (OR https://github.com/tesseract-ocr/tesseract/wiki/Training-Tesseract for older tesseract version). It says it use neural network-based recognition engine. ALSO “Tesseract 4.00 takes a few days to a couple of weeks. Even with all this new training data, you might find it inadequate for your particular problem, and therefore you are here wanting to retrain it.”. IT’D TAKE A FEW DAYS – WEEKS??? IT SEEMS SAME WITH TRAINING OPENCV. IF I HAVE PLENTY OF TIME I CAN DO THAT. ACTUALLY IT’S INTERESTING!

11. Install Language
    For example to install english and many other files, pls see https://github.com/tesseract-ocr/tesseract/wiki/Data-Files. I downloaded english language https://sourceforge.net/projects/tesseract-ocr-alt/files/tesseract-ocr-3.02.eng.tar.gz/download.
    <OLD>Then extract the zip file ‘tesseract-ocr-3.02.eng.tar.gz’. then move all files in /tesseract-ocr/tessdata/ to /tesseract/tessdata/
    DONT FORGET TO POINT OUT ‘TESSDATA_PREFIX’!
    
    teddy@teddy-K43SJ:~/Documents/cpp/tesseract$ export TESSDATA_PREFIX='/home/teddy/Documents/cpp/tesseract/tessdata/'

    1	teddy@teddy-K43SJ:~/Documents/cpp/tesseract$ export TESSDATA_PREFIX='/home/teddy/Documents/cpp/tesseract/tessdata/'

    
    </OLD>
    <NEW>It’d be much better to copy/move the ‘tessdata’ directory into /usr/local/share/tessdata/ than copy/move them into /cpp/tesseract/tessdata/ above (the OLD> because we dont have to type ‘export TESSDATA_PREFIX…’ everytime we need to scan an image. I did this after did the old one
    
    teddy@teddy-K43SJ:~/Documents/cpp/tesseract$ sudo cp tessdata/* /usr/local/share/tessdata/

    1	teddy@teddy-K43SJ:~/Documents/cpp/tesseract$ sudo cp tessdata/* /usr/local/share/tessdata/

    
    </NEW>
    AT FIRST I FORGOT ABOUT THIS. WHEN I DID A TEST, HERE IS THE MESSAGE

    Here is the image source (‘phototest.tif’) And here is the result in /tesseract/output.txt
    
    This is a lot of 12 point text to test the ocr code and see if it works on all types of file format. The quick brown dog jumped over the lazy fox. The quick brown dog jumped over the lazy fox. The quick brown dog jumped over the lazy fox. The quick brown dog jumped over the lazy fox.

    NOTE : IT BETTER TO NOT USE FILENAME WITH HAS SPACE BECAUSE TESSERACT CAN’T FIND IT!
    ALSO USE IMAGE WITH HIGH RESOLUTION! OR WE CAN DO THE TRAINING STUFF (IF WE HAVE PLENTY OF TIME!!!)

14. Question: Can we use tesseract to read/scan pdf file?
    pls read: http://kiirani.com/2013/03/22/tesseract-pdf.html
    http://www.barryhubbard.com/linux/converting-pdf-to-text-using-tesseract/
    http://stackoverflow.com/questions/30925218/converting-a-pdf-to-text-using-tesseract-ocr
    TESSERACT CAN’T DO THIS DIRECTLY. IT SAID TO CONVERT THE PDF TO TIFF IMAGE FIRST! ALSO THE MULTI PAGE PDF NEED TO BE CONVERTED TO MULTI TIFF FILES! READ http://www.barryhubbard.com/linux/converting-pdf-to-text-using-tesseract/ TO SEE THE SCRIPT TO DO THAT!
