- SHAPECLUSTERING(1)
- ==================
- :doctype: manpage
- NAME
- ----
- shapeclustering - shape clustering training for Tesseract
- SYNOPSIS
- --------
- shapeclustering -D 'output_dir'
- -U 'unicharset' -O 'mfunicharset'
- -F 'font_props' -X 'xheights'
- 'FILE'...
- DESCRIPTION
- -----------
- shapeclustering(1) takes extracted feature .tr files (generated by
- tesseract(1) run in a special mode from box files) and produces a
- file *shapetable* and an enhanced unicharset. This program is still
- experimental, and is not required (yet) for training Tesseract.
- OPTIONS
- -------
- -U 'FILE'::
- The unicharset generated by unicharset_extractor(1).
- -D 'dir'::
- Directory to write output files to.
- -F 'font_properties_file'::
- (Input) font properties file, where 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'
- -O 'FILE'::
- The output unicharset that will be given to combine_tessdata(1).
