Any help would be greatly appreciated.
I would like to do something fairly simple and that's reduce the types of
characters Tesseract looks for to be just AlphaNumeric, 0-9 a-z A-Z . I'm
using the very latest version 3.02.02. I want to do this because Tesseract
is doing things like confusing M with |'U'| . Notice the pipe and single
quotes. I'd like to remove any punctuation like that to reduce errors.
My first attempt was to
1) Edit the default eng.cub.lm and eng.cub.lm_ files in the tessdata
directory.
2) Remove the non-AlphaNumeric punctuation characters.
3) Run combine_tessdata to generate a new eng.traineddata
Unfortunately this isn't working. Here's the directory listing and the
output I get in red below.
