Hi, Can you please send a copy of all your source data files..eg font_properties, unicharset etc which version of Tesseract are you using 3.01 or 3.02 ? So I can try and compile a traineddata file. I am currently unable to do so using jTesseract or train.ps1 powershell script.
So I am looking for people with complete source data files to try and compare. Any help is always appreciated Richard On Thursday, March 29, 2012 6:31:53 AM UTC+11, nkantan r wrote: > > hi > i know there are two tamil trained data files corresponding to Latha > and Lohit fonts; going through the box and tif files i understand that > the boxes for combined consonants (உயிர்மெய்) are selected as > individual (for eg: கே is selected as individual ே and க instead of a > merged கே.
