MFTRAINING(1) ============= :doctype: manpage 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 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.) OPTIONS ------- -U 'FILE':: (Input) The unicharset generated by unicharset_extractor(1) -F 'font_properties_file':: (Input) font properties file, each line is of the following form, where each field other than the font name is 0 or 1: *font_name* *italic* *bold* *fixed_pitch* *serif* *fraktur* -X 'xheights_file':: (Input) x heights file, each line is of the following form, where xheight is calculated as the pixel x height of a character drawn at 32pt on 300 dpi. [ That is, if base x height + ascenders + descenders = 133, how much is x height? ] *font_name* *xheight* -D 'dir':: Directory to write output files to. -O 'FILE':: (Output) The output unicharset that will be given to combine_tessdata(1) SEE ALSO -------- tesseract(1), cntraining(1), unicharset_extractor(1), combine_tessdata(1), shapeclustering(1), unicharset(5) COPYING ------- Copyright \(C) Hewlett-Packard Company, 1988 Licensed under the Apache License, Version 2.0 AUTHOR ------ The Tesseract OCR engine was written by Ray Smith and his research groups at Hewlett Packard (1985-1995) and Google (2006-present).
