Hello,
I want to read word by word from sub images. I use below code to get sub
> image
> int x1 = 50, y1 = 50, tempW = 100, tempH = 100;
>
>
> tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
api->Init(NULL, "eng");
Mat im = imread("1.jpg");
cv::Mat sub = im(cv::Rect(x1, y1, tempW, tempH)); // x, y, width, height
api->SetImage((uchar*)sub.data, sub.size().width, sub.size().height,
> sub.channels(), sub.step1());
Now, I want to read each word via :
tesseract::ResultIterator* ri = api->GetIterator();
tesseract::PageIteratorLevel level = tesseract::RIL_WORD;
if (ri != 0) {
do {
const char* word = ri->GetUTF8Text(level);
//float conf = ri->Confidence(level);
int x1, y1, x2, y2;
ri->BoundingBox(level, &x1, &y1, &x2, &y2);
printf("word: '%s'; \t; BoundingBox: %d,%d,%d,%d;\n",
word, x1, y1, x2, y2);
delete[] word;
} while (ri->Next(level));
}
I get error... How can I do this?
