tesseract create traineddata or modify the data

[Tony H]

Hi,

I think my question is not the first one in this forum, but I need the help :-)

I want to convert a PDF-file to a TXT-file. I use ghostsript and tesseract to realise this. This process works but Ithe convertation is successful for just 90%.

example: In the pdf-file is the word "NO" and in TXT-file is the word "HO".

process: PDF - TIFF - TXT

I want to upload my TIFF-file in a software and I want to set to that the "N" is a "N" and not a "H" - I hope you can understand me :-)

After that I create my traineddata-file and the convertation works fine for 99,9%.

So wich software I will need for that and how it will works?   jTessBoxEditor?

Thank you in advance
