It should be possible in tesseract 3.02 (there is C++ or C API) with
something like this (c++ code snippet):
...
const char *searchForWord = "name";
api->Recognize(0);
tesseract::ResultIterator* ri = api->GetIterator();
tesseract::PageIteratorLevel level = tesseract::RIL_WORD;
if (ri != 0) {
do {
const char* text = ri->GetUTF8Text(level);
if (strcmp(text, searchForWord) == 0) {
float conf = ri->Confidence(level);
int x1, y1, x2, y2;
ri->BoundingBox(level, &x1, &y1, &x2, &y2);
printf("text: '%s''; conf: %.2f; BoundingBox: %d,%d,%d,%d;\n",
text, conf, x1, y1, x2, y2);
}
delete[] text;
} while (ri->Next(level));
}
...
Instead of printf use your highlight routine (e.g. different
highlight color based on confidence value ;-) )...
