I'm usuing mingw + openCV in my current project.
It has been built for work in QT IDE...
I just need to use OCR into my project and yet, could not find any
instruction on internet.
I actually need to run the code below from QT...
What are my next steps to make this happen?
#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>
using namespace std;
int main()
{
char *outText;
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
// Initialize tesseract-ocr with English, without specifying tessdata
path
if (api->Init(NULL, "eng")) {
fprintf(stderr, "Could not initialize tesseract.\n");
exit(1);
}
// Open input image with leptonica library
Pix *image = pixRead("/usr/src/tesseract/testing/phototest.tif");
api->SetImage(image);
// Get OCR result
outText = api->GetUTF8Text();
cout << ("OCR output:\n%s", outText);
// Destroy used object and release memory
api->End();
delete api;
delete [] outText;
pixDestroy(&image);
return 0;
}
