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).
