NAME
----
mftraining - feature training for Tesseract
SYNOPSIS
--------
mftraining -U 'unicharset' -O 'lang.unicharset' 'FILE'...
DESCRIPTION
-----------
mftraining takes a list of .tr files, from which it generates the
2012-02-10 06:55:47 +08:00
files *inttemp* (the shape prototypes), *shapetable*, and *pffmtable*
(the number of expected features for each character). (A fourth file
called Microfeat is also written by this program, but it is not used.)
