tesseract api with load_system_dawg and load_freq_dawg

Question

How to set load_system_dawg and load_freq_dawg to false ??

I need to disable the dictionary.. So I guess these are the two parameteres I need to set to false?

tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
if(api->Init(NULL, "dan+eng")){
    // error
}
api->SetImage(image);
api->Recognize(0);

Answer 1

1. In your tessdata directory create a configs directory
2. Create a file config (you will pass name of config file later in code)
3. Fill your config file with following text

load_system_dawg     F    
load_freq_dawg       F

4. Modify your code

   auto     numOfConfigs = 1;
   auto     **configs    = new char *[numOfConfigs];
   configs[i] = (char *) "name of your config file";
   
   tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
   if(api->Init(NULL, "dan+eng", tesseract::OEM_DEFAULT, configs, numOfConfigs, nullptr, nullptr, false)){
       // error
   }
   

P.S. It is also possible to do with last couple of arguments of Init function, feel free to try them out yourself.
