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:

where each line is of the following form, where each field other than the font name is 0 or 1:

-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? ]
