Disable dictionary in Tesseract

问题

How can I disable dictionary corrections when running Tesseract for English language?

I'm currently running tesseract as a child process.

回答1:

Try to set these variables (put them in a config file) to false:

load_system_dawg 
load_freq_dawg
load_punc_dawg
load_number_dawg
load_unambig_dawg
load_bigram_dawg
load_fixed_length_dawgs

Also read How to increase the trust in/strength of the dictionary? in the FAQ. From it:

For tesseract-ocr < 3.01 try upping NON_WERD and GARBAGE_STRING in dict/permute.cpp to maybe 3 or even 5.

For tesseract-ocr >= 3.01 try increasing the variables language_model_penalty_non_freq_dict_word and language_model_penalty_non_dict_word in a config file. By default they are 0.1 and 0.15 respectively.
