Hi Dimitry, with the guidelines provided from you, I prepared a strong
cup of coffee and start reading the top part of baseapi.h
Q1
Init(datapath, language, OcrEngineMode);
What is the normal setting of OcrEngineMode?
I try to use the :Recognize(ETEXT_DESC* monitor) method.
>>> There are two PARTS to the Recognize method
Part ONE:
Q2: which of the following is USED In normal running mode of
tessearct.exe to recognize text
if (tesseract_->tessedit_resegment_from_line_boxes)
page_res_ = tesseract_->ApplyBoxes(*input_file_, true,
block_list_);
else if (tesseract_->tessedit_resegment_from_boxes)
page_res_ = tesseract_->ApplyBoxes(*input_file_, false,
block_list_);
else
page_res_ = new PAGE_RES(block_list_, &tesseract_-
>prev_word_best_choice_); <<My guess>
if (tesseract_->tessedit_make_boxes_from_boxes) {
tesseract_->CorrectClassifyWords(page_res_);
return 0;
}
Part TWO:
Q3: which of the following is USED In normal running mode of
tessearct.exe to recognize text
if (tesseract_->interactive_mode) {
tesseract_->pgeditor_main(rect_width_, rect_height_, page_res_);
// The page_res is invalid after an interactive session, so
cleanup
// in a way that lets us continue to the next page without
crashing.
delete page_res_;
page_res_ = NULL;
return -1;
} else if (tesseract_->tessedit_train_from_boxes) {
tesseract_->ApplyBoxTraining(*output_file_, page_res_);
} else if (tesseract_->tessedit_ambigs_training) {
FILE *training_output_file = tesseract_-
>init_recog_training(*input_file_);
// OCR the page segmented into words by tesseract.
tesseract_->recog_training_segmented(
*input_file_, page_res_, monitor, training_output_file);
fclose(training_output_file);
} else {
// Now run the main recognition.
tesseract_->recog_all_words(page_res_, monitor, NULL, NULL, 0);
<<My guess>
}
