如何将Tesseract 3.05.01的load_system_dawg和load_freq_dawg设为false以禁用词典？

Got it, let's get this sorted for you! For Tesseract 3.05.01, you can adjust those two parameters right after initializing your TessBaseAPI instance using the SetVariable() method. Here's how to modify your existing code:

tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
if(api->Init(NULL, "dan+eng")){
    // Handle your error logic here
}

// Add these two lines to disable dictionary loading
api->SetVariable("load_system_dawg", "false");
api->SetVariable("load_freq_dawg", "false");

api->SetImage(image);
api->Recognize(0);

Quick notes on how this works: #

• SetVariable() lets you override Tesseract's default config values post-initialization. For boolean settings, you pass "true" or "false" as string values (the API expects string inputs here, not raw booleans).
• load_system_dawg controls loading of the core system dictionary (the standard list of valid words), while load_freq_dawg handles the frequency dictionary (a list of commonly used words). Disabling both turns off dictionary-based word guessing and correction entirely.

Just make sure to call these SetVariable() lines after Init() but before SetImage() or Recognize()—that way the settings kick in during the recognition process.
