*Hi All,*
*When i am trying to get information of word wise font attributes not
getting result. I choose ocr engine as a OEM_LSTM_ONLY. If i
choose OEM_TESSERACT_ONLY then getting correct result. Please suggest.
Thanks in advance. *
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
// Initialize tesseract-ocr with English, without specifying tessdata path
if(api->Init(NULL, "eng", tesseract::OEM_LSTM_ONLY)) {
fprintf(stderr, "Could not initialize tesseract.\n");
exit(1);
}
//api->SetVariable("save_blob_choices", "T");
//api->SetVariable("tessedit_char_whitelist","0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ./-");
//api->SetVariable("tessedit_ocr_engine_mode","10");
api->SetPageSegMode(tesseract::PSM_AUTO_ONLY);
api->SetVariable("chop_enable", "1");
api->SetImage((uchar*)Result.data,Result.cols,Result.rows,1,Result.cols);
time(& Start);
char* out = api->GetUTF8Text();
time(& End);
Result.release();
dif = difftime(End,Start);
printf("\nTesseract Processing Time %lf\n",dif);
// Tesseract bounding box finding Word Wise
time(& Start);
tesseract::ResultIterator* ri = api->GetIterator();
char* word;
const char *font_name;
bool bold, italic, underlined, monospace, serif, smallcaps;
int pointsize, font_id;
if(ri != 0){
do{
//tesseract::Orientation orientation;
//tesseract::WritingDirection writing_direction;
//tesseract::TextlineOrder textline_order;
//float deskew_angle;
//ri->Orientation(&orientation,&writing_direction,&textline_order,&deskew_angle);
word = ri->GetUTF8Text(tesseract::RIL_WORD);
if(word != 0 && word[0] != '\0' && word[1] != ' ' && word[0] != ' '){
float conf = ri->Confidence(tesseract::RIL_WORD);
int x1, y1, x2, y2;
if(conf > 0)
{
font_name = ri->WordFontAttributes(&bold, &italic, &underlined,
&monospace, &serif,
&smallcaps, &pointsize,
&font_id);
ri->BoundingBox(tesseract::RIL_WORD, &x1, &y1, &x2, &y2);
fprintf(fpout,"%s %d %d %d %d %d %d %d %d %d %d %d %d %s\n",word, x1, y1,
x2,
y2,pointsize,bold,italic,underlined,monospace,serif,smallcaps,font_id,font_name);
