Thanks for your answer. I managed to get the bounding boxes with an
IGrouper in the following way:
autodel<IGrouper> grouper(make_StandardGrouper());
grouper->setSegmentation(segmented);
for (int k = 0; k < grouper->length(); ++k) {
rectangle r = grouper->boundingBox(k);
}
I know that it doesn't give the unique candidates, but it tries to
group them in order to find some real character. Now I would like to
call a character classifier to find a classification to use with
grouper->setClass() function. I tried in the following way:
autodel<glinerec::IModel> classifier;
FILE * modelFile = fopen("/usr/local/share/ocropus/models/
default.model","rb");
classifier =
dynamic_cast<glinerec::IModel*>(load_component(modelFile));
but it always returns a null pointer. Am I missing something? Which is
the best way to instantiate a single character classifier and classify
a character candidate?
