Hi Sibi, Please see http://vietocr.sourceforge.net/training.html for details about jtessboxeditor. It requires Java Runtime Environment <http://www.oracle.com/technetwork/java/javase/downloads/index.html> 6.0 or later.
I have used it only on windows, but I guess it will run under ubuntu if you have the java environment. Please check with Quan about it. For tamil training source files sample, please download http://sourceforge.net/projects/tesseracthindi/files/Tamil%20Training%20Files/tam.zip/download Note that it is a large file (37 mb) as it has the sample tif/box pairs. You can use the files as a start for tamil training. I have not used the tamil training data provided with tesseract and cannot comment on it. Possibly it is better than the sample file provided by me because I just wanted to provide you with a framework for training with Jtessboxeditor to improve it. BTW, I noticed that new language related files have been added to the repository and you can get the tamil training text used by google at https://code.google.com/p/tesseract-ocr/source/browse/tam/tam.training_text?spec=svn.langdata.9204c02c18daedaedc8aeaab1c1dd99e544cc932&repo=langdata&r=9204c02c18daedaedc8aeaab1c1dd99e544cc932 All training related files for tamil are at https://code.google.com/p/tesseract-ocr/source/browse/tam/?repo=langdata&r=9204c02c18daedaedc8aeaab1c1dd99e544cc932 Hope this helps you.
