Character template libraries
Specifies a
file of character template libraries
, which is used on recognition.
Character templates are topological models of text characters (letters, special
symbols etc.), with which raster text characters are recognized.
The list contains DEFAULT.OCR and CYRILLIC.OCR files, included in the standard
shipment. Using the "default" file, the OCR module can recognize characters of the
English alphabet, digits, signs, punctuation marks and special symbols (the first half
of ASCII table). CYRILLIC file enables recognition of all the above mentioned plus
Russian characters.
*
You can also train the OCR to recognize other text characters. See “Training
OCR” below.
During the
training
process, the OCR engine creates letter templates and writes
them to the library. You can save letter templates in an existing library file or the
one created by you.
Þ
If you use your own file of character template libraries, then OCR will
recognize characters described in this file only.
*
The folder for saving files of characters templates libraries is set in the
WiseImage tab of the
Options
dialog box of the system AutoCAD, as
described in “Standard directories Section” on page 36.
To place on layer
In this list you can set the name of an AutoCAD layer, on which the texts obtained
as a result of the OCR operation will be placed.
Training OCR
Using the standard WiseImage OCR features, you can recognize the characters of
the English alphabet, digits, punctual marks and special symbols (first half of ASCII
table). These character templates (topological models) are stored in special files
called
character
template libraries
. These files are by default stored in the OCR
folder of the WiseImage root folder.
The WiseImage OCR module can be trained to recognize any character. For this
purpose you can add new character templates to one of the available libraries or
create your own library.
