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).
