OCR Sensitivity

Hi, I am really new to Tesseract OCR 3.0 as a static DLL within a windows envionment and have the majority of what I want working but... Is there a way to increase the sensitivity of the OCR engine? For instance, I am passing JPG images that purely have images of registration plates (ANPR

Dimitry, I had generated traineddata(Kannada) files sucessfully from the old datafiles of 2.xx last year. There is discussion by spohorsky in the forum how to do. sriranga(78) ♫ On Thu, Mar 3, 2011 at 5:42 PM, Dmitry Silaev daemons2...@gmail.com wrote: Manuel, It's quite an interesting
