This is my image
<https://lh3.googleusercontent.com/-7l8wq8oybP4/WmuBhKbYe6I/AAAAAAAAAQQ/B2dbuxEf_zcDM2LdZH3z9hUEzvmtUOTpwCLcBGAs/s1600/danger_module.png>
And this is my code
#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>
int main()
{
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
api->Init(".\\tessdata", "eng");
Pix *image = pixRead("image.png");
api->SetImage(image);
api->SetPageSegMode(tesseract::PSM_SINGLE_CHAR);
api->SetSourceResolution(300);
api->SetVariable("classify_bln_numeric_mode", "1");
//api->SetVariable("tessedit_char_whitelist", "0123456789");
api->SetRectangle(61, 4, 38, 22);
char *outText = api->GetUTF8Text();
cout << outText << endl;
api->End();
return 0;
}
I will get a character *A*. Why my *SetVariable("classify_bln_numeric_mode",
"1");* don't work normally? And even I use
*SetVariable("tessedit_char_whitelist",
"0123456789");*. The result is same still. How to read a digit from a
specify rectangle?
