7a116ce8bb More formatting fixes from clang tidy 2017-04-28 13:38:32 -07:00

1cc511188d Added extra Init that takes a memory buffer or a filereader function pointer to enable read of traineddata from memory or foreign file systems. Updated existing readers to use TFile API instead of FILE. This does not yet add big-endian capability to LSTM, but it is very easy from here. 2017-04-27 15:48:23 -07:00

c2f5e9b849 If there is no explicit renderer(s), default to TessTextRenderer 
Revert fd429c32, 43834da7, 05de195e.

See #49, #59.

The code in this commit solves the issue in a more elegant way, IMHO.

Now you can use:
  * `tesseract eurotext.tif eurotext txt pdf`
  * `tesseract eurotext.tif eurotext txt hocr`
  * `tesseract eurotext.tif eurotext txt hocr pdf`

NOTE:
  With `tesseract eurotext.tif eurotext`
  or `tesseract eurotext.tif eurotext txt`
  the psm will be set to '3', but...
  With `tesseract eurotext.tif eurotext txt pdf`
  or `tesseract eurotext.tif eurotext txt hocr`
  the psm will be set to '1'.

0e868ef377 Major change to improve layout analysis for heavily diacritic languages: 
Tha, Vie, Kan, Tel etc.
There is a new overlap detector that detects when diacritics
cause a big increase in textline overlap. In such cases, diacritics from
overlap regions are kept separate from layout analysis completely, allowing
textline formation to happen without them. The diacritics are then assigned
to 0, 1 or 2 close words at the end of layout analysis, using and modifying
an old noise detection data path.
The stored diacritics are used or not during recognition according to the
character classifier's liking for them.
