I have been trying to test Leadtools for handwriting recognition, but I can't seem to understand how to get started on this. We develop apps using the digital pen and paper technology. We need to recognise the text entered on handwritten forms, so we need to access the ICR functionality via VBScript and ASP.

Can anyone help me on how to do this? I've looked through the help files and see that the ICR component of LeadTools is supplied by a 3rd party company - reRecognition, but there is no mention of the way of getting this to work.

I'm not a very advanced coder, so please try make explanations simple and easy to follow.

Thanks

Zayne

Hello,

 

We support the LEADTOOLS ICR module (which is a part from the OCR engine) that converts the handwritten text and numbers into a readable strings and documents.

So, the ICR module is the OCR part that is specialized in hand printed recognition.

The ICR module is represented by two main recognition modules:

-          HNR hand-printed numeral recognition module:

This module can be used for recognition of hand-printed numerals and four additional signs. If further hand-printed characters are to be recognized, the use of the RECOGMODULE_RER_PRINTED recognition module is recommended.

-          RER hand-printed recognition module.

 

So to programming with the ICR modules, you will begin with the OCR functions, and then you can make useful from using the SetHandPrintOptions method, which sets the hand print options used by the OCR engine.

 

Also, some of the LTZoneData properties can be used when recognizing hand printed documents, such as:

-----------------------------

ZoneData As LTZoneData

.. .

ZoneData.FillMethod = FM_HANDPRINT

ZoneData.RecognizeModule = RECOGNIZE_MODULE_HAND_PRINTED_NUMERAL

ZoneData.CharacterFilter = CHAR_FILTER_DIGIT

.. .

-------------------------------

 

For more information about the ICR module, you can refer to:

you can check out the configurations below:

ZONEDATA ZoneData;
memset(&ZoneData, 0, sizeof(ZONEDATA));
ZoneData.uStructSize = sizeof(ZONEDATA);
ZoneData.FillMethod = FILL_HANDPRINT;
ZoneData.RecogModule = RECOGMODULE_AUTO;
ZoneData.Type = ZONE_FLOWTEXT;
ZoneData.uFlags = 0;
ZoneData.pfnCallback = NULL;
ZoneData.pUserData = NULL;

/* Add in the zones here*/

RECOGNIZEOPTS RecogOpts;
memset(&RecogOpts, 0, sizeof(RECOGNIZEOPTS));
RecogOpts.uStructSize         = sizeof(RECOGNIZEOPTS);
RecogOpts.nPageIndexStart     = 0;
RecogOpts.nPagesCount         = 1;
RecogOpts.bEnableSubSystem    = TRUE;
RecogOpts.bEnableCorrection   = TRUE;
RecogOpts.SpellLangId         = LANG_ID_ENGLISH;
RecogOpts.pszFileName         = _T("c:\\result.rdf");

After setting the options, you can just use L_DocRecognize() function to recognize the content in respective added zones!

Hope this will help you!
