Hey Thilanka, I ran into a similar problem when I only needed it to look at hexidecimal values. What I ended up doing was creating a separate "langauge" that only contained the specified characters. So you could create a langauge of numbers and a language with letters and use tesseract to read each part of your image using the appropriate language.
The web address below shows you how to train tesseract for a specific language. Hope this helps. http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract On Mar 6, 11:46 pm, Thilanka Kaushalya <lgtkausha...@gmail.com> wrote: > Hi, > > I'm using Tesseract for my letter recognition project and currently > the recognitions is quite good. > The letters are hand written.But there are some problems when I used it to > recognise the letter "O" and > number "0".
