HI, I am trying to give a string pattern into TesseractEngine object when
it is initiated.
I am using "A .Net wrapper for tesseract-ocr" 3.0.1.0 in C#.
Here is my code:
C# code
using( TesseractEngine engine = new TesseractEngine(
@"./tessdata",
"eng",
EngineMode.Default,
"bazzar" ) ) // here load config from bazzar *important*
{
engine.SetVariable( "tessedit_char_whitelist",
"ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-" );
engine.SetVariable( "language_model_penalty_non_freq_dict_word", "1" );
engine.SetVariable( "language_model_penalty_non_dict_word", "1" );
string user_patterns_suffix;
engine.TryGetStringVariable( "user_patterns_suffix", out
user_patterns_suffix );
using( Page page = engine.Process( bitmap, PageSegMode.SingleLine ) )
{
...
}
}
tessdata/configs/bazzar
load_system_dawg F
load_freq_dawg F
user_words_suffix user-words
user_patterns_suffix user-patterns
tessdata/eng.user-patterns
25\w\w\w\d\d
tessdata/eng.user-words

Output from tesseract:
25HAR16
I have successfully inserted user-words and user-patterns into the
tesseract object.
But the tesseract doesn't seem to refer to my user-words list because it
keeps returning
HAR instead of MAR.
How can I force to read \w\w\w in the user-words list?
