<div class="paragraph"><p>Tesseract needs to know the set of possible characters it can output.
|
|
|
|
|
To generate the unicharset data file, use the unicharset_extractor
|
|
|
|
|
program on the same training pages bounding box files as used for
|
|
|
|
|
clustering:</p></div>

</div></div>

<div class="paragraph"><p>The unicharset will be put into the file <em>dir/unicharset</em>, or simply
|
|
|
|
|
<em>./unicharset</em> if no output directory is provided.</p></div>
|
|
|
|
|
<div class="paragraph"><p>Tesseract also needs to have access to character properties isalpha,
|
|
|
|
|
isdigit, isupper, islower, ispunctuation. all of this auxilury data
|
|
|
|
|
and more is encoded in this file. (See unicharset(5))</p></div>
|
|
|
|
|
<div class="paragraph"><p>If your system supports the wctype functions, these values will be set
|
|
|
|
|
automatically by unicharset_extractor and there is no need to edit the
|
|
|
|
|
unicharset file. On some older systems (eg Windows 95), the unicharset
|
|
|
|
|
file must be edited by hand to add these property description codes.</p></div>
|
|
|
|
|
<div class="paragraph"><p><strong>NOTE</strong> The unicharset file must be regenerated whenever inttemp, normproto
|
|
|
|
|
and pffmtable are generated (i.e. they must all be recreated when the box
|
|
|
|
|
file is changed) as they have to be in sync. This is made easier than in
|
|
|
|
|
previous versions by running unicharset_extractor before mftraining and
|
|
|
|
|
cntraining, and giving the unicharset to mftraining.</p></div>
