Hi Dmitri,
here's the snipet:
//numberStrip is an opencv IplImage object
tess->SetImage((uchar*) numberStrip->imageData, numberStrip-
>width, numberStrip->height,
numberStrip->depth / 8,
numberStrip->widthStep);
text = tess->GetUTF8Text(); //text is fine, it contains digits
from the OpenCV image
Boxa* bounds = tess->GetWords(NULL);
l_int32 count = bounds->n; // count > 3 million :(
for(int i=0; i<count; i++){
Box* b = bounds->box[i];
/// coords below are all 0's, and sometimes I have bad access
int x = b->x;
int y = b->y;
int w = b->w;
int h = b->h;
}
