Hello Greg, thank for your help. I have new problems, noy related with the Engine's accuracy. I attempt to explain you in my poor english.

I need to know if the LeadTools v. 15 have a training
system to send samples of handwritten characters of the user. I need to improve the accuracy of the recognized words. I have
been create a user dictionary but i can't work with this. How can i do
to work properly with a user dictionary ?. Please, send me a example about how to use user dictionary.

I need your help to tune the engine to perform recognition with much more accuracy than i get now.


I send a .rar file with sample of images and results. The images and the results have the same name. Each directory is a set of tests.

The parameters that i used are the following:

            Leadtools.Document.RasterDocumentFillMethod.Handprint
            Leadtools.Document.RasterDocumentRecognizeModule.RerPrinted
            Leadtools.Document.RasterDocumentCharacterFilter.Uppercase
            Leadtools.Document.RasterDocumentZoneType.FlowText
            EnableSubsystem = True
            EnableCorrection = True
            SpellLanguageId.Leadtools.Document.RasterDocumentLanguage.Spanish
            RasterDocumentResultOptions.Format = Leadtools.Document.RasterDocumentFormatType.RecAsciiStandard
            RasterDocumentResultOptions.FormatLevel = Leadtools.Document.RasterDocumentFormatLevel.Full


Thanks in advance for your help.

Hello,

There is no training system in the OCR engine.

The quality of some of the images you attached is very bad, and the text is not clear. In cases like this, defining a use dictionary will not help much, because the user dictionary only works if you have clear text, but the words are not part of the language. For example, if you have an English document, and you want to add the words "Maen Badwan", they will not be part of the language, so you can add them in a user dictionary.

For more information about user dictionary, including code samples, please read the following topics in the LEADTOOLS .Net documentation:
- Working With A Dictionary
- SetUserDictionary Method
- GetUserDictionarySection Method

Thanks,

Hello Maen,

Thank you for your suggestions. I improve the quality and size of the
images and the engine recognized around much better. Now my questions are two:
1) How can i distribute and install my own application without installing LeadTools 15 Main Eval?

2) My application only uses the following DLL to make ICR:
Leadtools.dll
Leadtools.Codecs.dll
Leadtools.Document.dll

I need to know what is the cost of the licenses of these libraries, which
products should to buy and know  all the different types of licencing and pricing with or without run-time. I need to know all the possible options.

Thanks in advance for your anwers.

Hello,

(1) About the files needed to deploy your application, please read the help topic "Files to be Included with Your Application" in the LEADTOOLS .Net Documentation.

(2) About the cost and the required licenses, please send your query to our sales department at sales@leadtools.com. They will provide you with detailed information about the cost and the exact product(s) that you need to purchase.

Thanks,
