Mmhh.. I'm working on stable version, not SVN => no AdaptToWordStr()
in baseapi.cpp
in ccmain/tfacepp.cpp, there is:
Tesseract::recog_word_recursive(
WERD *word, // word to do
DENORM *denorm, // de-normaliser
POLY_MATCHER matcher, // matcher function
<----------
POLY_TESTER tester, // tester function
<----------
POLY_TESTER trainer, // trainer function
<----------
BOOL8 testing, // true if answer driven
<-------
WERD_CHOICE *&raw_choice, // raw result
BLOB_CHOICE_LIST_CLIST *blob_choices, // list of blob lists
WERD *&outword // bln word output
)
inside of which there is the definition for tess_tester and
tess_trainer:
tess_tester = testing ? tester : NULL;
tess_trainer = testing ? trainer : NULL;
but then, those tess_* aren't used at all. The only function I was
able to find is call_train_tester, but it's never called (and marked
as deadcode):
/
**********************************************************************
* call_train_tester
*
* Called from Tess with a blob in tess form.
* Convert the blob to editor form.
* Call the trainer setup by the segmenter in tess_trainer.
**********************************************************************/
#if 0 // dead code
void call_train_tester( //call a tester
const STRING& filename,
TBLOB *tessblob, //blob to test
BOOL8 correct_blob, //true if good
char *text, //source text
inT32 count, //chars in text
LIST result //output of matcher
) {
PBLOB *blob; //converted blob
BLOB_CHOICE_LIST ratings; //matcher result
blob = make_ed_blob (tessblob);//convert blob
if (blob == NULL)
return;
//make it right type
convert_choice_list(result, ratings);
if (tess_trainer != NULL)
(*tess_trainer) (filename, blob, tess_denorm, correct_blob, text,
count, &ratings);
delete blob; //don't need that now
}
#endif
BTW, we reach the function following those steps ("--" means unuseful
for us):
...
recog_all_words(--, --, --, --);
classify_word_pass2(--, --, --);
match_word_pass2(--,--, --, --);
correct_segment_pass2( -- , -- , &Tesseract::tess_default_matcher,
tess_training_tester, -- , -- , --);
recog_word(--, --, matcher=&Tesseract::tess_default_matcher,
tester=NULL, trainer=tester (?!), testing=TRUE, --, --, --);
recog_word_recursive(--, --,
matcher=&Tesseract::tess_default_matcher, tester=NULL, trainer=tester,
testing=TRUE, --, --, --);
Here {
tess_tester = testing ? tester : NULL; => tess_tester = NULL;
tess_trainer = testing ? trainer : NULL; => tess_trainer = tester;
(???)
}
and then, nothing happens..!! :-(
Thanks,
Davide
