How do I increase/decrease the strength of the dictionary in tesseract 3 ?

在常见问题解答中说我需要更改"NON_WERD"的值，并且 "GARBAGE_STRING"，但在Tesseract 3中不存在.

In the FAQ it says I need to change the value of "NON_WERD" and "GARBAGE_STRING" but they do not exist in Tesseract 3.

推荐答案

根据 http://code.google.com/p/tesseract-ocr/wiki/常见问题解答，您可以更改以下变量:

According to http://code.google.com/p/tesseract-ocr/wiki/FAQ, you change these variables:

enable_new_segsearch    1
language_model_penalty_non_freq_dict_word 0.2
language_model_penalty_non_dict_word 0.3

增加它们的值，使Tesseract更偏向于词典单词.

Increase their values to make Tesseract more biased to dictionary words.

注意:您必须设置enable_new_segsearch，否则它们将无效

Note: You must set enable_new_segsearch, otherwise they'll have no effect.
