CubeRecoContext * GetCubeRecoContext ()
 
init_cube_objects

Instantiates Tesseract object's CubeRecoContext and TesseractCubeCombiner. Returns false if cube context could not be created or if load_combiner is true, but the combiner could not be loaded.

bool init_cube_objects (bool load_combiner, TessdataManager *tessdata_manager)
 
run_cube_combiner

Iterates through tesseract's results and calls cube on each word, combining the results with the existing tesseract result.

void run_cube_combiner (PAGE_RES *page_res)
 
cube_word_pass1

Recognizes a single word using (only) cube. Compatible with Tesseract's classify_word_pass1/classify_word_pass2.

void cube_word_pass1 (BLOCK *block, ROW *row, WERD_RES *word)
 
cube_recognize_word

Cube recognizer to recognize a single word as with classify_word_pass1 but also returns the cube object in case the combiner is needed.

CubeObject * cube_recognize_word (BLOCK *block, WERD_RES *word)
 
cube_combine_word

Combines the cube and tesseract results for a single word, leaving the result in tess_word.

void cube_combine_word (CubeObject *cube_obj, WERD_RES *cube_word, WERD_RES *tess_word)
 
cube_recognize

Call cube on the current word, and write the result to word. Sets up a fake result and returns false if something goes wrong.

bool cube_recognize (CubeObject *cube_obj, BLOCK *block, WERD_RES *word)
 
fill_werd_res

Fill Tesseract's word result fields with cube's.

void fill_werd_res (const BoxWord &cube_box_word, const char *cube_best_str, WERD_RES *tess_werd_res)
 
extract_cube_state

Extract CharSamp objects and character bounding boxes from the CubeObject's state. The caller should free both structres.

bool extract_cube_state (CubeObject *cube_obj, int *num_chars, Boxa **char_boxes, CharSamp ***char_samples)
 
create_cube_box_word

Fill the given BoxWord with boxes from character bounding boxes. The char_boxes have local coordinates w.r.t. the word bounding box, i.e., the left-most character bbox of each word has (0,0) left-top coord, but the BoxWord must be defined in page coordinates.

bool create_cube_box_word (Boxa *char_boxes, int num_chars, TBOX word_box, BoxWord *box_word)
 
eval_word_spacing()

The basic measure is the number of characters in contextually confirmed words. (I.e the word is done) If all words are contextually confirmed the evaluation is deemed perfect.

Some fiddles are done to handle "1"s as these are VERY frequent causes of fuzzy spaces. The problem with the basic measure is that "561 63" would score the same as "56163", though given our knowledge that the space is fuzzy, and that there is a "1" next to the fuzzy space, we need to ensure that "56163" is preferred.

The solution is to NOT COUNT the score of any word which has a digit at one end and a "1Il" as the character the other side of the space.

Conversly, any character next to a "1" within a word is counted as a positive score. Thus "561 63" would score 4 (3 chars in a numeric word plus 1 side of the "1" joined). "56163" would score 7 - all chars in a numeric word + 2 sides of a "1" joined.

The joined 1 rule is applied to any word REGARDLESS of contextual confirmation. Thus "PS7a71 3/7a" scores 1 (neither word is contexutally confirmed. The only score is from the joined 1. "PS7a713/7a" scores 2.

BOOL8 digit_or_numeric_punct (WERD_RES *word, int char_position)
 
inT16 eval_word_spacing (WERD_RES_LIST &word_res_list)
 
fix_sp_fp_word()

Test the current word to see if it can be split by deleting noise blobs. If so, do the business. Return with the iterator pointing to the same place if the word is unchanged, or the last of the replacement words.

void fix_noisy_space_list (WERD_RES_LIST &best_perm, ROW *row, BLOCK *block)
 
void fix_sp_fp_word (WERD_RES_IT &word_res_it, ROW *row, BLOCK *block)

float blob_noise_score (TBLOB *blob)
 
void break_noisiest_blob_word (WERD_RES_LIST &words)
 
fix_fuzzy_spaces()

Walk over the page finding sequences of words joined by fuzzy spaces. Extract them as a sublist, process the sublist to find the optimal arrangement of spaces then replace the sublist in the ROW_RES.

Parameters
monitorprogress monitor

BLOCK_LIST *  blocks,
TO_BLOCK_LIST *  to_blocks,
BLOBNBOX_LIST *  diacritic_blobs,
Tesseract *  osd_tess,
OSResults *  osr 
)

Auto page segmentation. Divide the page image into blocks of uniform text linespacing and images.

Resolution (in ppi) is derived from the input image.

The output goes in the blocks list with corresponding TO_BLOCKs in the to_blocks list.

If !PSM_COL_FIND_ENABLED(pageseg_mode), then no attempt is made to divide the image into columns, but multiple blocks are still made if the text is of non-uniform linespacing.

If diacritic_blobs is non-null, then diacritics/noise blobs, that would confuse layout anaylsis by causing textline overlap, are placed there, with the expectation that they will be reassigned to words later and noise/diacriticness determined via classification.

If osd (orientation and script detection) is true then that is performed as well. If only_osd is true, then only orientation and script detection is performed. If osd is desired, (osd or only_osd) then osr_tess must be another Tesseract that was initialized especially for osd, and the results will be output into osr (orientation and script result).

bool tesseract::Tesseract::BelievableSuperscript ( bool  debug,
const WERD_RES &  word,
float  certainty_threshold,
int *  left_ok,
int *  right_ok 
) const

Return whether this is believable superscript or subscript text.

We insist that:

  • there are no punctuation marks.
  • there are no italics.
  • no normal-sized character is smaller than superscript_scaledown_ratio of what it ought to be, and
  • each character is at least as certain as certainty_threshold.
Parameters
[in]debugIf true, spew debug output
[in]wordThe word whose best_choice we're evaluating
[in]certainty_thresholdIf any of the characters have less certainty than this, reject.
[out]left_okHow many left-side characters were ok?
[out]right_okHow many right-side characters were ok?
Returns
Whether the complete best choice is believable as a superscript.

◆ GetSubAndSuperscriptCandidates()

void tesseract::Tesseract::GetSubAndSuperscriptCandidates ( const WERD_RES *  word,

float *  leading_certainty,
int *  num_rebuilt_trailing,
ScriptPos *  trailing_pos,
float *  trailing_certainty,
float *  avg_certainty,
float *  unlikely_threshold 
)

Determine how many characters (rebuilt blobs) on each end of a given word might plausibly be superscripts so SubAndSuperscriptFix can try to re-recognize them. Even if we find no whole blobs at either end, we will set *unlikely_threshold to a certainty that might be used to select "bad enough" outlier characters. If *unlikely_threshold is set to 0, though, there's really no hope.

Parameters
[in]wordThe word to examine.
[out]num_rebuilt_leadingthe number of rebuilt blobs at the start of the word which are all up or down and seem badly classified.
[out]leading_pos"super" or "sub" (for debugging)
[out]leading_certaintythe worst certainty in the leading blobs.
[out]num_rebuilt_trailingthe number of rebuilt blobs at the end of the word which are all up or down and seem badly classified.
[out]trailing_pos"super" or "sub" (for debugging)
[out]trailing_certaintythe worst certainty in the trailing blobs.
[out]avg_certaintythe average certainty of "normal" blobs in the word.
[out]unlikely_thresholdthe threshold (on certainty) we used to select "bad enough" outlier characters.

◆ recog_all_words()

bool tesseract::Tesseract::recog_all_words ( PAGE_RES *  page_res,
ETEXT_DESC *  monitor,
const TBOX *  target_word_box,
const char *  word_config,
int  dopasses 
)

recog_all_words()

Walk the page_res, recognizing all the words. If monitor is not null, it is used as a progress monitor/timeout/cancel. If dopasses is 0, all recognition passes are run, 1 just pass 1, 2 passes2 and higher. If target_word_box is not null, special things are done to words that overlap the target_word_box: if word_config is not null, the word config file is read for just the target word(s), otherwise, on pass 2 and beyond ONLY the target words are processed (Jetsoft modification.) Returns false if we cancelled prematurely.

Parameters
page_respage structure
monitorprogress monitor
word_configword_config file
target_word_boxspecifies just to extract a rectangle
dopasses0 - all, 1 just pass 1, 2 passes 2 and higher

◆ SetupPageSegAndDetectOrientation()

ColumnFinder * tesseract::Tesseract::SetupPageSegAndDetectOrientation ( PageSegMode  pageseg_mode,
BLOCK_LIST *  blocks,
Tesseract *  osd_tess,
OSResults *  osr,
TO_BLOCK_LIST *  to_blocks,
Pix **  photo_mask_pix,
Pix **  music_mask_pix 
)

Sets up auto page segmentation, determines the orientation, and corrects it. Somewhat arbitrary chunk of functionality, factored out of AutoPageSeg to facilitate testing. photo_mask_pix is a pointer to a NULL pointer that will be filled on return with the leptonica photo mask, which must be pixDestroyed by the caller. to_blocks is an empty list that will be filled with (usually a single) block that is used during layout analysis. This ugly API is required because of the possibility of a unlv zone file. TODO(rays) clean this up. See AutoPageSeg for other arguments. The returned ColumnFinder must be deleted after use.

Attempt to split off any high (or low) bits at the ends of the word with poor certainty and recognize them separately. If the certainty gets much better and other sanity checks pass, acccept.

This superscript fix is meant to be called in the second pass of recognition when we have tried once and already have a preliminary answer for word.

Try splitting off the given number of (chopped) blobs from the front and back of the given word and recognizing the pieces.

Parameters
[in]num_chopped_leadinghow many chopped blobs from the left end of the word to chop off and try recognizing as a superscript (or subscript)
[in]leading_certaintythe (minimum) certainty had by the characters in the original leading section.
[in]leading_pos"super" or "sub" (for debugging)
[in]num_chopped_trailinghow many chopped blobs from the right end of the word to chop off and try recognizing as a superscript (or subscript)
[in]trailing_certaintythe (minimum) certainty had by the characters in the original trailing section.
[in]trailing_pos"super" or "sub" (for debugging)
[in]wordthe word to try to chop up.
[out]is_gooddo we believe our result?
[out]retry_rebuild_leading,retry_rebuild_trailingIf non-zero, and !is_good, then the caller may have luck trying to split the returned word with this number of (rebuilt) leading and trailing blobs / unichars.
Returns
A word which is the result of re-recognizing as asked.
