<title>DESCRIPTION</title>
|
|
<simpara>shapeclustering(1) takes extracted feature .tr files (generated by
|
|
tesseract(1) run in a special mode from box files) and produces a
|
|
file <emphasis role="strong">shapetable</emphasis> and an enhanced unicharset. This program is still
|
|
experimental, and is not required (yet) for training Tesseract.</simpara>
