383dcf70b5 Document some more config options for tesseract
Clarify also the name(s) of the generated OCR result file(s):
Tesseract does not create a file named outbase.txt by default.

Fix also a sentence in the language section.

Don't set page segmentation mode for unlv config
2018-10-04 22:00:40 +02:00

c6f759148b Don't set page segmentation mode for unlv config
Setting the page segmentation mode to 6 ("Assume a single uniform block
of text") typically improves the layout detection for such texts, but
should not be done in the config file.

unlvtests/runtestset.sh adds `--psm 6` explicitly, so test results
won't change when using that script.

This is similar to commit ecfee53bac.

Allow orientation detection with any traineddata

26bfd2b9d3 Allow orientation detection with any traineddata
While orientation and script detection (OSD) normally requires
osd.traineddata to detect both, it must also be possible to do
only orientation detection with eng.traineddata or any other
traineddata.

Enforce osd.traineddata only if there was no `-l` command line option.

Commit 27ce472666 was too restrictive.

Don't set page segmentation mode for hocr, pdf and tsv configs
2018-10-04 16:24:52 +02:00
Stefan Weil
ecfee53bac Don't set page segmentation mode for hocr, pdf and tsv configs
Setting the page segmentation mode in those config files gives unexpected
results: the text recognized when no config or only txt is given changes
if both txt and any of hocr, pdf or tsv is chosen.

In a test set of nearly 200 pages from historical books, using
segmentation mode 1 is typically slightly better than the default,
but there are also cases where it is much worse. Therefore the user
should be able to decide which page segmentation mode is best.

Old results for hocr, pdf or tsv now need an explicit `--psm 1` for
reproduction.

The report from Coverity Scan is a false positive.

Nevertheless the code can be rewritten and optimized
a little bit to fix that report.

9a1f14f2aa Fix CID 1395882 (Uninitialized scalar variable)
The implementation for ICOORD only allows division by scale != 0.

Do the same for FCOORD by asserting that scale != 0.0f,
so undefined program behaviour will be caught.

Only print "Merging rows..." if textord_debug_blob==true (like all the other debug messages).
Otherwise, there are a lot of "Merging rows..." messages in console output.

5338a5a8d5 Don't trigger a deliberate SIGSEGV for fatal errors in release code
The error message "segmentation fault" confuses most users,
so enforce a segmentation fault only in debug code.

Release code simply calls the abort function.
