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. 205
